Chapter Summary

Key plot points and events

• Orochimaru recognizes that the map’s landmarks match the area around Daimyo Castle, despite the map seeming older than the castle itself. He concludes that the map may predate the castle and leads Yui and Nai toward the marked ruins.
• They follow the Hot Spring River, using its course, the surrounding mountain, and the map to confirm they are heading in the right direction.
• On the way, Orochimaru warns Yui and Nai to leave the Land of Hot Water after their search. According to his intelligence, Princess Hanami is attracted to women and allegedly abducts and abuses women who catch her eye.
• Yui recalls Hanami’s earlier attention and worries that the princess may have chosen her. Nai notices Yui’s unease and teases her about being afraid of women who like women.
• The group reaches a bathhouse that Orochimaru thinks is a likely location for the ruins. He admits he is not certain, so Yui suggests they search nearby hot springs systematically.

Character developments

• Yui uses the map and landscape to verify their route, but becomes anxious after hearing about Hanami—especially because she remembers the princess looking at her.
• Nai Hyuga is observant and playful, quickly spotting Yui’s discomfort and teasing her about it.
• Orochimaru acts as their guide and source of intelligence, though his confidence falters when they reach the bathhouse and he cannot confirm it is the right place.

• At the bathhouse, Yui questions Orochimaru’s certainty and ultimately proposes searching the area.

Key plot points and events

• Orochimaru believes the entrance to some ruins may be hidden in the women’s hot spring. To investigate without drawing attention, he changes into a kimono and enters the women’s section with Yui and Nai Hyuga.
• At the reception desk, he poses as one of three “sisters.” The proprietor accepts the disguise and directs them to the largest natural pool, a communal bath that is empty because the establishment has just opened.
• After paying the deposit, the group reaches the pool. Yui reimburses Orochimaru, while Nai checks the map and finds no visible sign of ruins.
• Orochimaru reasons that the ruins may lie beneath the spring, perhaps near the underground channel feeding its water. He proposes sending Shadow Clones to trace the water’s flow, then digging an entrance.

Character developments and interactions

• Orochimaru is briefly embarrassed about entering the women’s bath, but quickly commits to the disguise. His unexpectedly convincing appearance in women’s clothing astonishes both Yui and Nai; Nai especially struggles to reconcile his natural look with the absence of breasts.
• Yui is amused by the contrast between this seemingly innocent Orochimaru and the more brazen person she expects him to become. She follows his lead and pays him back for her share.
• Nai reacts with open surprise to Orochimaru’s appearance, then focuses on examining the map and questioning whether the ruins are really there.
• The three cooperate in the investigation, though Yui and Nai are initially skeptical of Orochimaru’s theory.

Significant themes

• Appearance and identity: Orochimaru’s disguise is so convincing that it unsettles his companions, highlighting how easily outward appearance can blur expectations.
• Practical investigation and speculation: The group moves from a map search to Orochimaru’s logical—but unconfirmed—theory about the spring’s underground source.
• Humor through contrast: The awkwardness of Orochimaru’s disguise and his companions’ reactions provide comedy amid the mystery of the ruins.

Key plot points and events

• Yui uses her Byakugan to trace warm water beneath the bathhouse’s hot spring, helping Orochimaru’s Shadow Clones locate a crack between the stone tiles.
• Though the crack looks too small to lead anywhere, Orochimaru trusts the map’s directions. Yui investigates underwater and discovers that a large passage lies beyond it.
• Yui warns that breaking the opening too widely could unleash water into the bathhouse. She proposes making a controlled gap and sealing it again with Earth Release once they are through.
• Yui cuts the opening with her sword, but the rush of water nearly sweeps her away. Orochimaru and Nai enter first; Yui follows and gets briefly stuck before forcing her way through.
• Orochimaru seals the entrance behind them. Meanwhile, a bathhouse attendant investigates the sudden eruption of water, finds the visitors gone, and returns to her work.
• Inside the passage, Yui reopens the sealed entrance to restore the original crack.

Character developments and interactions

• Yui takes charge of the search and shows practical judgment, cautioning Orochimaru about the risk of flooding the bathhouse. She also reveals an unusual ability to communicate underwater by sending sound through the water. Her confidence about fitting through the opening proves misplaced.
• Orochimaru is initially uncertain when the crack seems implausibly small, but the map convinces him to persist. He is astonished by Yui’s underwater communication and accepts her safer plan.
• Nai Hyuga stays nearby and follows the others through the passage without much comment.
• The trio cooperate closely: Yui locates and opens the entrance, Orochimaru and Nai pass through first, and Orochimaru seals it behind them.

Significant themes

• Teamwork and complementary skills: Yui’s Byakugan and judgment combine with Orochimaru’s map-reading and Earth Release.
• Caution versus haste: Yui prevents a reckless opening that could have flooded the bathhouse.
• Comedic mishaps amid adventure: The dramatic water eruption, the attendant’s confusion, and Yui getting stuck provide humor alongside the discovery of the passage.

Yui, Nai Hyuga, and Orochimaru search the hot spring for the entrance to the ruins. Orochimaru discovers a deep, widening passage and swims down; Yui and Nai follow, holding hands as the current grows stronger and the pressure builds. Nai struggles to hold her breath, making Yui regret bringing her, but they press on.
Orochimaru spots a narrow crack in the rock. Yui enlarges it with her sword, and the three enter a cooler, illuminated chamber. They swim upward and emerge beside glowing stones and carved murals, confirming they have found the ruins. Nai recovers her breath and realizes she needs to train her underwater endurance. Orochimaru surfaces exhausted, changes out of his soaked disguise, and complains that the others did not wait for him.
Orochimaru asks how Yui spoke underwater. She explains that she has just devised a way to use chakra to create sound waves, allowing speech beneath the water.
Character developments and interactions: Yui shows quick thinking and concern for Nai, while Nai recognizes a weakness and resolves to improve. Orochimaru remains inquisitive, impressed by Yui’s ingenuity, and the group shares lighthearted amusement over his return to his usual appearance.
Themes: Resourcefulness under pressure, the limits of preparation, and learning from hardship. Yui’s improvised technique also highlights experimentation as a path to discovery.

Key events

• The three search for the Ruin’s entrance, but neither Yui’s Byakugan nor Orochimaru’s inspection reveals anything unusual.
• They split up to search the cavern. Nai notices that the fluorescent rock is the only feature that stands out and discovers that the eye-like murals all face toward it.
• Nai and Yui fly up to inspect the rock. Nai strikes and shatters it, revealing no immediate mechanism; moments later, she spots what appears to be a door in the ceiling where the rock had hung.

Character developments and interactions

• Orochimaru is impressed by Yui’s quick ingenuity, then proposes a systematic search when his own investigation fails.
• Nai shifts from initially lingering in place to making the key discovery by studying the murals. Her impulsive decision to smash the rock alarms Yui, and Nai recognizes the danger and accepts the warning.
• Yui verifies Nai’s deduction and cautions her to be more careful. Their cooperation turns Nai’s observation into a promising lead.

Significant themes

• Observation and inference: Careful attention to the murals reveals a clue that direct searching missed.
• Ingenuity and experimentation: Yui’s underwater sound-wave idea and the group’s investigation reflect practical curiosity.
• Recklessness and responsibility: Nai’s bold action may have advanced the search, but it also teaches her to consider the risks to herself and others.

Plot points and events

• Yui and Nai Hyuga discover an ornate stone door embedded in the cave ceiling and wonder whether the ruin has been turned upside down.
• Orochimaru recognizes the site from fluorescent ore like that found near the ruin where he discovered the Kusanagi Sword. He explains that the ore concealed the entrance, though he cannot say whether opening the door is dangerous.
• Yui and Nai fly back up to open it, leaving Orochimaru behind. He uses Earth Release to raise himself on a stone pillar.
• Nai offers to open the door, but Yui refuses so she can take responsibility for any danger. After a strenuous effort, she pushes it open and quickly moves away in case of traps.
• Nai checks that Yui is unharmed. Orochimaru arrives on his pillar, dusty from being knocked off balance by Yui’s powerful winds.

Character developments and interactions

• Nai supports and worries about Yui, offering to take the risk herself and checking on her afterward.
• Orochimaru provides the key clue linking the entrance to his earlier discovery, while maintaining his sardonic humor. He complains when the others leave him behind, but proves resourceful by using Earth Release to ascend.

Plot points and events

• Yui, Nai Hyuga, and Orochimaru investigate a ruin that appears to be standing on end. They enter through a stone doorway, using chakra to keep their footing despite the strange gravity.
• Yui’s Byakugan reveals a dark passage inside. Orochimaru insists the ruin resembles one where he previously found a Kusanagi Sword, and says the sword should be in the main chamber.
• As they proceed, the entrance abruptly closes behind them. Orochimaru remains confident that they can find another way out, while Yui is uneasy.
• They reach a second stone door. Orochimaru forces it open; a cold draft extinguishes their torch. When he relights it and sees what is beyond, he recoils and warns that they are in danger.

Character developments and interactions

• Yui is capable and observant, using her Byakugan and Wind Release to navigate the ruin, but she grows increasingly wary—especially of Orochimaru’s motives and the unexplained closing door.
• Orochimaru is confident and determined to reach the Kusanagi Sword. He takes the lead and brushes off setbacks, though the sight beyond the second door visibly frightens him.
• Nai Hyuga follows Yui’s lead and remains remarkably composed, even when the entrance shuts unexpectedly.
• Yui questions Orochimaru’s certainty and his calm attitude; he reassures her about the ruin’s layout and possible exits, but his final reaction suggests the danger is greater than he expected.

Key plot points and events

• Inside the Kusanagi Sword Ruin, Orochimaru discovers a huge, expanding vortex in a mass of black mist. His instincts warn that it is dangerous, so he urges Yui and Nai to retreat.
• The stone door behind them is shut, and the passage begins to crumble beneath Nai. The three fall as the corridor collapses, dodging the shower of stone.
• Orochimaru grabs Nai’s foot for help, but she resists his touch. Before she can shake him off, the vortex’s suction seizes all three.
• Yui pulls Nai close and tells her to hold on. The vortex swallows them along with the falling rubble.
• Yui experiences intense cold and loses consciousness. She later wakes alone in a stone chamber, with Xiao You on her shoulder. Her Byakugan detects no sign of Nai or Orochimaru.

Character developments

• Yui reacts quickly under pressure, using Wind Release and Hakutaku to defend herself. She shows protectiveness toward Nai, and her distress at waking alone reveals how strongly she fears losing her.
• Nai Hyuga is wary and physically guarded, resisting Orochimaru’s attempt to grab her. In the vortex, however, she accepts Yui’s embrace and holds on.
• Orochimaru is unusually shaken by the ruin and admits he does not understand what is happening. His composure gives way to visible fear.
• Xiao You is relieved and emotional when Yui wakes, having feared she was dead.

Significant themes

• After waking, Yui reunites with Xiao You, then urgently searches for Nai and Orochimaru.

Key plot points and events

• Yui wakes in a sealed stone chamber with Xiao You, separated from Nai Hyuga and Orochimaru after a black-mist vortex apparently scattered them. Xiao You says Yui woke within six hours of them.
• Worried about Nai but unable to help from inside the chamber, Yui searches for an exit. Her Byakugan finds no mechanism, so she tests the walls with her sword and discovers one sounds hollow.
• Yui’s Sword Aura dents the unusually hard wall but does not break through immediately. Meanwhile, the opposite wall develops countless tiny holes and begins leaking fast-rising water.
• The water burns Yui’s feet: it is acid. She protects her legs with Earth Release and strikes the weakened, gouged wall again, finally opening a narrow passage.
• Yui and Xiao You squeeze through into a candle-lined corridor decorated with relief carvings. Rather than rush blindly ahead, Yui decides to block the acid water with Earth Release and inspect the corridor first.

Character developments

• Yui moves from anxiety and frustration to decisive action. She prioritizes escape and survival, using observation, swordsmanship, and ninjutsu under pressure. Her curiosity about the carvings briefly distracts her, but she quickly returns to the danger at hand.
• Xiao You remains supportive and alert, suggesting that Yui break through the wall and warning her as the acid water rises. Their concern helps keep Yui focused.

Significant themes

• Resourcefulness under pressure: Yui adapts when no obvious escape route exists, testing the walls and combining her abilities to overcome the obstacle.
• Danger concealed beneath appearances: The chamber’s water initially seems harmless, but it is corrosive acid; the stone walls also prove tougher than expected.
• Caution versus urgency: Though escape is urgent, Yui recognizes that the corridor may hold further dangers and chooses to assess it rather than charge ahead.

Character interactions

• Yui questions Xiao You about how long they were separated from her, seeking reassurance about the time elapsed.
• Xiao You offers practical advice and alerts Yui to both the wall’s hollow section and the rising acid.
• Yui relies on Xiao You’s warnings while taking charge of the escape, then agrees that they should secure the chamber before exploring further.

Key plot points and events

• After sealing the crack that released highly corrosive acid water, Yui heals her badly injured heels. She and Xiao You suspect the acid appeared because they damaged the Stone Chamber.
• To test the corridor, Yui sends a shadow clone ahead. Xiao You warns that traps might be waiting at the far end, so Yui waits rather than following immediately.
• The warning proves right: the corridor’s far section traps the clone in a spongy floor while saw blades and spikes attack, destroying her. Yui learns the corridor’s hidden mechanism through the clone’s memories.
• Yui decides to destroy the traps instead of trying to evade them. She uses another clone to trigger them, then cuts down the spikes with sword aura.
• Acid begins leaking from tiny holes in the walls whenever Yui destroys something, confirming her suspicion that damage triggers the acid as punishment. As the liquid spreads, Yui armors her legs with rock and charges into the corridor. The chapter ends as she attacks the saw blades.

Character developments and interactions

• Yui shifts from cautious testing to bold, improvisational problem-solving. She protects Xiao You, trusts its warning, and then embraces destruction as a practical way forward.
• Xiao You is frightened by the acid and traps but contributes an important insight: the danger may be at the corridor’s end. Yui listens to its caution, while Xiao You hides in her sleeve once the acid returns.
• Their relationship is cooperative: Xiao You advises and warns; Yui takes its concerns seriously while keeping it out of harm’s way.

Significant themes

• Caution and ingenuity: Careful observation prevents Yui from walking into the trap, while shadow clones let her gather information at a distance.
• Destruction as a tool: Yui turns force into a deliberate strategy, calling it an art when ordinary passage seems impossible.
• Escalating consequences: Each attempt to alter the dangerous environment triggers another threat, forcing Yui to act quickly and adapt.

Plot points and events

• Yui defeats the corridor’s spinning saw blades with Sword Aura, then clears a sticky stretch of flooring by leaping over it.
• At the corridor’s end, she encounters the same black mist that brought her into the Ruin. As acid water rises, she chooses to enter it, hoping it is safer than staying behind.
• The mist transports her to a dark, dusty wooden room. Disoriented and severely thirsty, she uses Water Release to fill a carved gourd and drink.
• Once she has recovered, Yui worries the gourd may be poisoned because it is an artifact from the Ruin. Xiao You senses faint sealing power in it and suggests it is a tool used in sealing rituals.

Character developments

• Yui shows resourcefulness under pressure, using her Byakugan, ninjutsu, and quick judgment to escape immediate dangers.
• Her exhaustion and thirst leave her briefly confused and careless, but she regains her composure and reflects on the risks of acting without caution.

Key plot points and events

• Yui examines a cracked, dried-out gourd and finds that it holds fresh water and traces of sealing power. She decides to keep it.
• The gourd repeatedly pops out when Yui tries to seal it in a scroll. Xiao You theorizes that its sealing power is stronger than the scroll’s, so Yui hangs it at her waist instead.
• The pair realize they are still inside the ruin. Yui sets out to find Nai Hyuga, who was pulled into the ruin with her, while warning Xiao You that the acid water may not have been the only danger.
• They leave a dusty wooden house and enter a vast, dark cavern containing a towering dead tree hung with extinguished candles.
• When Yui looks back, the wooden house has vanished. Xiao You then spots a fast-moving dark shape in the cavern and urges Yui to use her Byakugan to investigate.

Character developments

• Yui is curious and practical: she recognizes the gourd’s potential, keeps it despite its odd behavior, and stays composed when the house disappears. She remains focused on finding Nai.
• Xiao You is observant and helps explain the gourd’s sealing properties, but the eerie events frighten her, making her seek Yui’s protection.

Significant themes

• Mystery and supernatural danger: The gourd’s unusual power, the vanished house, and the shadowy presence suggest the ruin operates by strange rules.
• Caution amid exploration: Yui proceeds carefully, aware that the dangers may be worse than what they have already encountered.
• Discovery and uncertainty: Both the object and the cavern raise questions that neither character can yet answer.

Character interactions

• Yui relies on Xiao You’s knowledge to understand why the gourd cannot be sealed in a scroll, then carries it openly.
• Xiao You voices her fear and asks Yui to use her Byakugan on the dark shape; Yui’s calm resolve contrasts with Xiao You’s anxiety.

Plot points and events

• After the shadow vanishes from view, Yui prepares to punish Xiao You for supposedly lying. Xiao You spots it again and insists it is approaching, but Yui still cannot see it.
• An unseen voice addresses Yui by name and mocks her. Realizing Xiao You was telling the truth, Yui puts her away for safety and draws Hakutaku.
• Xiao You warns that Yui’s Byakugan cannot detect the figure and tells her to switch it off. Though this leaves Yui effectively blind, Xiao You guides her toward the attacker.
• Yui fires a small fireball, briefly revealing a child-sized figure in tight black clothing. The blast appears to kill it, leaving a tar-like puddle.
• When Yui approaches to inspect the remains, a grotesque, plastic-bag-like shape springs out and startles her.

Character developments and interactions

• Yui moves from skepticism and irritation to alertness once the voice confirms Xiao You’s warning. She acts quickly to protect Xiao You, but remains confident enough to approach the apparent remains.
• Xiao You is frightened yet persistent: she repeatedly warns Yui, then proves useful by identifying the figure’s direction when Yui cannot see it. Her desire to stay hidden in Yui’s clothing also fuels Yui’s suspicion.
• Their relationship combines teasing and trust. Yui threatens to punish Xiao You, while Xiao You pleads for belief; in the danger, Yui protects her and relies on her guidance.

Significant themes

• Limits of perception: Yui’s powerful Byakugan cannot detect the creature, while Xiao You can see it.
• Trust under uncertainty: Yui initially dismisses Xiao You, but must accept her account when the danger becomes undeniable.
• False reassurance and suspense: The creature seems defeated with ease, only for its remains to spring back into action.

Key plot points and events

• Yui confronts a floating, transparent figure that Xiao You mistakes for a ghost. Her sword passes harmlessly through it.
• The figure recognizes Yui and makes lecherous advances, repeatedly attempting to touch her. Yui evades its first approach, then deliberately lets it pass through her to test her theory.
• Concluding that it is a “soul body,” Yui questions the creature, which bristles at being told it does not look human and boasts that she cannot harm it.
• When the figure drifts toward a giant dead tree, Yui uses the Spirit Transformation Technique to project a white spirit form. She catches the figure from behind and immobilizes it.

Character developments

• Yui stays composed and observant, using her Byakugan to see the figure after Fire Release removes the black substance that concealed it. She reasons through its nature and finds a way to engage it despite its apparent intangibility.
• Xiao You is terrified and hides in Yui’s sleeve, but still warns her to be careful.
• The transparent figure shifts from smug and predatory to startled and helpless once Yui demonstrates that she can affect it.

Significant themes

• Observation and adaptation: Yui turns failed attacks into clues and adjusts her approach.
• Appearance and identity: The creature takes offense when Yui questions whether it is human.
• Power and overconfidence: The figure assumes intangibility makes it untouchable, only to be caught by Yui’s unexpected technique.

Character interactions

• Xiao You panics and warns Yui, while Yui reassures it by hiding it in her sleeve.
• The figure taunts and threatens Yui; she remains calm, identifies it as a soul body, and challenges its confidence.
• Yui’s final move reverses their dynamic: the figure’s attempt to leave ends with it captured and face-to-face with her.
