Chapter Summaries

Leo revealed that his new magic, [Comet Pursuit], gave him flight, accelerating speed, and powerful protection, and he decided to test it in real combat. As he prepared for a week-long expedition into the deep floors, Ais volunteered to accompany him.

• Finn and the others learned that [Comet Pursuit] could protect Leo from attacks far stronger than his level and make him faster as it continued accelerating.
• The Loki Familia recognized that Leo’s new spell made him a formidable fighter, while Ais privately felt he might have surpassed her and Bete left in frustration.
• Leo told Finn he wanted to test his new magic and recent training in the Dungeon, planning to use the 18th and 28th Floors as bases before exploring the 37th Floor for about a week.
• Finn worried that Leo could not safely explore the deep floors alone and said he needed a strong companion.
• Ais resolutely offered to go with Leo.

Ais, Lefiya Viridis, Tiona, and Tione joined Leo’s planned Dungeon expedition, while Finn and the others set strict limits because Udaeus would soon respawn. Leo prepared for the trip with the group, still wary of the worm monsters and intent on growing stronger before confronting future dangers.

• Ais volunteered to accompany Leo into the deep levels, and Lefiya Viridis and Tiona also asked to join for training and to earn money.
• Finn persuaded Tione to join the party, and Riveria and Gareth warned everyone to stay within their limits.
• Finn ordered the group to return within a week and avoid going beyond the 37th Floor, since Udaeus would soon respawn there.
• Leo recalled the worm monsters that had destroyed Tiona’s first-generation Ullr and considered whether his foreknowledge of future events could still be trusted.
• Leo packed his Giant Battle Suit, Dragon Fang Sword, Emerald Staff, and potions, then met the others and set off toward Babel Tower.

Leo joined Ais, Tiona, Tione, and Lefiya on an expedition through the Dungeon, traveling toward the 37th Floor while avoiding unnecessary fights. On the 17th Floor, Tione noticed that Leo’s swordsmanship had become more measured and defensive than before.

• Leo and the Loki Familia members drew attention in Central Plaza, though he hid his face beneath his hood.
• The group entered Babel Tower and set out for the Labyrinth Garden on the 28th Floor before continuing toward the 37th Floor, where they planned to train and hunt monsters.
• Leo’s party rapidly descended the upper floors, using vertical shafts to speed their passage through the middle floors.
• On the 17th Floor, Leo, Ais, and Tiona charged into a group of Minotaurs and slaughtered them.
• Tione observed that Leo now used more rhythm and calculation in combat, sometimes keeping monsters alive to shield himself from others’ attacks.

Leo’s fighting style evolved during a battle with Minotaurs, and his party reached the 18th Floor after finding Goliath already defeated. They went to Rivira to sell their loot, where the town’s residents recognized the Loki Familia.

• Leo defeated the Minotaurs as his swordsmanship and combat instincts merged into a fluid fighting style, and Tiona, Tione, Ais, and Lefiya Viridis noticed his growth.
• Leo’s party reached the end of the 17th Floor, found Goliath absent, and cleared the monsters occupying its hall before descending.
• On the 18th Floor, Tione said they needed to sell their loot, and Ais invited Leo to visit Rivira, which he had never seen.
• Leo and the others crossed the lake to Rivira Town, learned it had been rebuilt 334 times, and drew attention from locals who recognized the Loki Familia.

Leo and the Loki Familia heard that someone had been murdered in Rivira, but Leo urged the group to stay out of the investigation. When Ais spotted a frightened dog-person girl carrying something that unsettled her, Leo followed her, and the group gave chase.

• Leo and his companions arrived in Rivira, where merchants treated them as wealthy customers and locals discussed Leo's rapid rise and fight against Goliath.
• Tione sold the group's spoils at a steep loss, and the Amazoness shopkeeper told them someone had been murdered in town.
• The shopkeeper said the victim's head had been crushed and suggested the killer might still be in Rivira, leaving Lefiya worried she could be targeted.
• Leo told the group not to get involved in the murder unless it concerned their Familia, and Tione agreed they should leave the matter to others.
• Ais noticed a hurried dog-person girl and felt troubled by something she was carrying, so Leo followed her and the others joined the chase.

Leo and Ais caught Lulune Louie, a Hermes Familia courier carrying cargo connected to a murdered messenger. When Lulune revealed the hidden item, Ais reacted with intense, inexplicable distress.

• Leo and Ais cornered Lulune Louie in Rivira after she fled from them, and she recognized them as Loki Familia adventurers.
• Lulune identified herself as a member of the Hermes Familia and said she had mistaken Leo and Ais for the killers who wanted her package.
• Leo deduced that a courier had secretly delivered the package to Lulune before being murdered, and his explanation confirmed her suspicions.
• Ais demanded to know what the cargo was, and Lulune admitted she had been instructed not to inspect or show it.
• Lulune opened the hidden compartment in her shoulder bag and removed a tightly cinched pouch, causing Ais's heart to race and her instincts to recoil.
• Lulune took the item from the pouch while Leo and Ais watched.

Leo and Ais confronted the woman who had murdered a deliveryman to steal Lulune’s green orb, while the strange fetus inside it caused Ais intense distress. After the woman attacked, Leo and Ais fought to protect Lulune, but the mysterious woman blew a reed flute, plunging Under Resort into chaos.

• Lulune revealed a green sphere containing a bizarre fetus, and Ais reacted with severe nausea and weakness when she saw it.
• A disguised woman ambushed Leo, but he blocked her sword; she removed her armor and the stolen face of the deliveryman, then demanded the orb.
• The woman tried to seize the orb and nearly struck Lulune, but Leo pushed Lulune clear and Ais engaged the attacker in a sword duel.
• Leo fired tracking meteors at the woman, who survived the explosions with only blackened skin and little apparent injury.
• When Ais questioned the woman about the murders and the orb, she blew a reed flute, and Under Resort descended into chaos.

• Leo faced a group of man-eating flower monsters charging into the alley.

Leo fought off the man-eating flowers in Rivira and tried to destroy the green orb, but its fetus escaped and transformed one of the monsters into a female-shaped creature. The mysterious woman called Ais “Aria,” leaving Ais stunned just as the new monster turned its attention toward her.

• Leo used meteors to kill the man-eating flowers surrounding him, then asked Lulune to find the green orb.
• The fetus inside the orb cried, escaped Leo’s first attack, and attached itself to a man-eating flower.
• The parasitized flower transformed into a female-shaped monster resembling the creature Leo and Ais had encountered on the 50th Floor.
• Ais realized that the fetus had transformed both monsters and demanded to know what the green orb was.
• The mysterious woman told Ais that they were alike and called her “Aria,” shocking Ais.
• Leo warned Ais as the new monster turned toward her and let out a piercing shriek.

A colossal man-eating flower rampaged through Rivira while Leo fought the mysterious woman who had attacked Ais. Leo used [Comet Pursuit] to overwhelm her with speed, then began a new spell as she realized his attacks had not injured her.

• The giant man-eating flower struck Ais into Rivira’s wall, then grew by devouring other man-eating flowers and began wrecking the town.
• The mysterious woman revealed her face and tried to take Ais, but Leo attacked her and challenged her to get past him.

• Ais arrived and struck the mysterious woman, joining Leo in the fight.
• Lefiya used [Arcs Ray] to devastate the man-eating flower woman, and Tiona and Tione finished it off.

• Leo and Ais fought through the man-eating flowers blocking their way, but the mysterious woman escaped before they could catch her.
• Tiona, Tione, and Lefiya reached Leo and Ais and found them silently watching the direction the mysterious woman had fled.

After the events in Rivira, Leo and the Loki Familia expedition pushed through the floors to the White Palace on the 37th Floor. There, Leo and Ais fought with unusual desperation, driven by the threat of the mysterious woman, while Tiona, Tione, and Lefiya worried about them.

• Rivira’s destruction drew little concern from the city, while the Guild investigated and the Loki Familia received Leo’s report about the green jewel, Lulune, and the mysterious woman.
• Loki sent Leo and the others a brief message saying they would discuss the events after the group returned.
• Leo and the others crossed the floors from the Great Tree Labyrinth to the Desert Labyrinth and reached their expedition’s target, the White Palace on the 37th Floor.

• Ais joined the fight and slaughtered the monsters even more ruthlessly, while Tiona, Tione, and Lefiya watched with concern.
• Leo resolved to become stronger because he remembered the mysterious woman’s threat to kill him, while Ais remained troubled by the woman calling her Aria.

Leo and his companions continued their lucrative expedition on the 37th Floor while honing their abilities, and Leo’s updated status showed his Dexterity had reached SSS. With his strength approaching the limit of Lv.4, he decided to prepare for a feat that could take him to Lv.5 and turned his attention toward an opponent in the White Palace.

• Leo, Ais, Tiona, Tione, and Lefiya spent several days exploring the 37th Floor, where Lefiya trained her Parallel Chanting and Leo refined his combat skills and [Comet Pursuit].
• The group sold most of their loot in Rivira for promissory notes, earning roughly ten million Valis in a few days while saving valuable drops to sell on the surface.
• Leo returned to the surface during a rest period, and Loki updated his status, revealing that his Dexterity had risen to SSS and his other attributes had greatly improved.
• Leo realized that his growth had broken past its former limits and that his status was nearing the cap for Lv.4.
• Leo decided to pursue a great feat to reach Lv.5 and, back on the 37th Floor, looked toward the central area of the White Palace at the opponent he had chosen.

Leo fought the Earthborn on the 37th Floor with overwhelming skill, prompting Tiona, Tione, and Lefiya Viridis to realize he was close to reaching Lv.5. Ais’s frustration and memories of the name Aria triggered a dark power, but Leo’s call brought her back to herself, leaving her silent as her companions gathered around her.

• Leo cut through the Earthborn, displaying strength that made Tiona, Tione, and Lefiya Viridis believe he was near his next level-up.
• Tione said Leo might need only one final great feat to become Lv.5, and Tiona realized he could catch up to the Loki Familia’s executives.

• Black flames appeared in Ais’s eyes as her combat power surged and she charged into the Earthborn horde.
• Leo called Ais’s name, stopping her enormous strike, and Tiona, Tione, and Lefiya Viridis rushed to protect her from the monsters.
• Leo silently stood beside Ais as she fell quiet, surrounded by her companions.

After Ais’s dangerous [Avenger] power awakened, Leo comforted her and the party prepared to leave the Dungeon. Leo then announced that he intended to challenge Udaeus, the 37th Floor’s boss, to earn the feat he needed to level up, shocking everyone.

• Ais’s companions worried over the unfamiliar, frightening power she had unleashed, while Leo recognized it as her [Avenger] skill and feared its consuming hatred.
• Leo took Ais’s hand, easing her distress, and Tiona proposed that the party return to Orario after their week-long expedition.
• Leo revealed that he needed one final great feat to level up and planned to challenge a powerful enemy.
• Lefiya Viridis realized Leo meant to fight Udaeus, and Tiona and Tione warned that the Lv.6 floor boss was far beyond what a Lv.4 adventurer could safely face.

Leo persuaded Ais, Tiona, Tione, and Lefiya to let him attempt to challenge Udaeus, with flight magic and armor as safeguards. The group reached the Throne Room, waited for the floor boss to spawn, and watched it emerge as Leo braced for the fight.

• Tione, Tiona, and Lefiya tried to dissuade Leo from fighting Udaeus alone, but he argued that he could retreat with his flight magic if necessary.
• Leo’s companions agreed to accompany him, and the five fought their way to the Throne Room on the 37th Floor.
• Before Leo entered the cavern, Lefiya gave him their magic potions, while Tiona and Tione handed over their Elixir supplies.
• Leo stood at the center of the Throne Room as Ais, Tiona, Tione, and Lefiya waited with him for two hours.
• The ground shook and split, and Udaeus burst into the hall with a thunderous roar as Leo’s expression turned grave.

Leo challenged Udaeus, the 37th Floor’s powerful floor boss, while Ais, Lefiya Viridis, Tiona, and Tione watched from the cavern entrance. He evaded Udaeus’s crushing blows and underground sword-stakes, but his meteors could not pierce its defense, leaving the battle difficult.

• Udaeus emerged before Leo, and Ais, Lefiya Viridis, Tiona, and Tione braced themselves as he faced the floor boss alone.
• Leo used his flight magic to dodge Udaeus’s strike and flew toward the Magic Stone exposed in its chest.
• Udaeus sent black inverted stakes bursting from the floor, forcing Leo to weave through the cavern to avoid them.
• Leo fired repeated Meteor Dance spells, but Udaeus smashed every meteor apart with its fists.
• Leo realized that defeating Udaeus would be difficult.

Leo fought Udaeus alone in the Throne Room, using flight and meteors to evade its sword-stake barrage until he broke through its defenses and exposed its Magic Stone. As Leo charged to destroy it, Udaeus struck him with a massive stake and hurled him into the ceiling.

• Leo and Udaeus traded meteors and mountains of sword-stakes while the watching women worried over the deadlock.
• Leo drank mind potions as his flying and attack spells rapidly drained his strength.
• Leo gambled by flying straight through a mountain of sword-stakes and striking Udaeus with Meteor Dance.
• The meteor shattered the bones protecting Udaeus's chest and exposed its Magic Stone.
• Leo charged the exposed stone with his Dragon Fang Sword, but Udaeus hit him with a huge rising stake and sent him crashing through the ceiling.

Udaeus revealed a black greatsword and unleashed a devastating attack that left Ais badly wounded. Leo and Ais joined forces against the floor boss as Tiona, Tione, and Lefiya supported them, bringing the battle into its final stage.

• Udaeus drew a black greatsword from an inverted stake and used its new combat mode to unleash a destructive strike that knocked Ais down and blasted Tiona and Tione aside.
• Leo ignored his injuries, drank three magic elixirs, and attacked Udaeus, but his sword was deflected by the boss’s repaired ribs.
• Ais recovered enough to return to the fight and helped Leo shatter Udaeus’s protective ribs.
• Leo and Ais evaded Udaeus’s sword and summoned groundspawn while Tiona and Tione rejoined the battle and Lefiya began chanting a spell.

Leo and Ais fought Udaeus through an exhausting battle and finally destroyed its magic stone. After Udaeus fell, both fighters lost consciousness as Lefiya and the others rushed to them.

• Leo and Ais fought Udaeus for more than an hour while Tiona, Tione, and Lefiya kept the Earthborn away.
• Leo struck Udaeus's exposed chest with a meteor spear, and Ais attacked with her ultimate skill, [Little Tempest].
• Ais's finishing move was blocked, but she pressed on toward Udaeus's magic stone, driven by memories of her parents and hatred for the black dragon.
• Leo knocked aside Udaeus's reaching hand, allowing Ais to stab its magic stone with the Desperate.
• Leo drove the Dragon Fang Sword through the magic stone, and Ais added her final strength until it shattered and Udaeus crumbled into ash.
• Leo and Ais fell unconscious, and Lefiya and the others ran toward them.
