• Vice-Captain Ashido remains alone in the air, fighting the endless stream of Hollows emerging from two rifts. Although he continues defeating them efficiently, exhaustion is clearly setting in.
• Yan Si urges Ashido to retreat and join the others, but Ashido refuses because he senses something deeply wrong with the rifts.
• Ashido suspects Yan Si may be concealing his true strength. Yan Si hides his unease and pretends to be an ordinary Fifth Seat, though his advanced Kidō spells suggest otherwise.
• Yan Si notices that Captain Kurayashiki Kenpachi is surrounded by an unusually concentrated swarm of Hollows. Ashido explains that Kurayashiki has cast Spirit Bait, making himself an irresistible target and drawing the Hollows away from the rest of the battlefield.
• Because Kurayashiki’s Spirit Bait is attracting the Hollows, he cannot leave the ground or approach the rifts without potentially causing an uncontrollable reaction. He functions as the battlefield’s primary shield and anchor.
• Yan Si uses Chain Lightning Pattern to destroy several Hollows, but realizes the spell has consumed nearly a tenth of his Spiritual Power. Fighting in the Human World, where spiritual energy is scarce, is rapidly becoming unsustainable.
• Yan Si asks whether the Shinigami’s Reiatsu Restriction Seals have been lifted. Ashido reveals that they were never imposed because the battlefield has already suffered catastrophic destruction, making concern for environmental damage irrelevant.
• This revelation means Ashido and Kurayashiki can fight at full strength—but it also leaves open the possibility that stronger enemies may now emerge.
• Without warning, a cracking sound echoes through the battlefield. A massive and malignant Reiatsu descends from above, overwhelming Ashido and disrupting his control of Reishi. Yan Si catches and steadies him.
• The separate crescent-shaped rifts begin merging into one another. They fuse into a gigantic black passage in the sky, radiating purple-black Reishi.

• Ashido is portrayed as determined and self-sacrificing. Despite exhaustion, he refuses to abandon the rifts because he senses an approaching threat. His willingness to endure the assault highlights his role as a defensive barrier.
• Kurayashiki Kenpachi is established as the battlefield’s strongest combatant and central protector. By using Spirit Bait, he deliberately exposes himself to overwhelming danger so the other Shinigami can survive.
• Ashido’s physical decline and Yan Si’s growing concern suggest that both are nearing their limits just as a far greater enemy appears.

Chapter Summary: The Demon Still Lost

Key Plot Points and Events

• Aizen approaches Yan Si during Kuchiki Kyōka’s banquet and asks for guidance in unlocking and training his Shikai.
• Aizen claims that his Zanpakutō is a “flowing-water type,” making it similar to Yan Si’s supposed ice- and snow-based Shikai, Scroll of Wind and Snow. He says Hirako Shinji was unable to advise him because his own Zanpakutō differs too much.
• Yan Si immediately suspects that Aizen’s request is not innocent. He considers whether Aizen has already realized that Scroll of Wind and Snow is a false or incomplete Shikai, and whether the request is intended to test Yan Si’s knowledge or reactions.
• Rather than refuse outright, Yan Si delays the matter by claiming that he must concentrate on writing Lord Kuchiki Kyōka’s story. He promises to discuss Zanpakutō training at a later time.
• Aizen accepts the postponement without visible displeasure, leaving Yan Si uncertain whether he has successfully avoided the trap.
• Back at the banquet, Yan Si is too preoccupied to enjoy the food or drink. Kensei Muguruma prevents Hirako and Kyōraku from pressuring him into drinking.
• After returning to his room, Yan Si analyzes the danger posed by Aizen’s Kyōka Suigetsu. He recognizes that seeing its Shikai release would allow Aizen to control all five senses through complete hypnosis.
• Since Aizen will likely demonstrate his Shikai if they train together, Yan Si begins searching for a way to witness the release without becoming hypnotized.
• In a separate scene in Rukongai, Gremmy and Yachiru become lost while trying to reach the Seireitei. Gremmy seriously considers whether they could simply cross the sea, while Yachiru angrily takes command of navigation.

Character Developments

• Yan Si: Becomes increasingly cautious and suspicious of Aizen. His ability to analyze hidden motives improves, but his paranoia also intensifies as he considers the many ways his response might expose him. He chooses strategic postponement rather than direct refusal and begins planning how to counter Kyōka Suigetsu.
• Aizen: Displays his usual politeness and apparent sincerity while carefully probing Yan Si. His request may be a test of Yan Si’s knowledge, his false Shikai, or his attitude toward Aizen. His calm acceptance of Yan Si’s delay keeps his true intentions ambiguous.
• Hirako Shinji: Is revealed to have already heard or observed Aizen’s claimed Shikai and accepted that it was too different from his own to advise on. This suggests Aizen has successfully presented a convincing false explanation of his ability.
• Kensei Muguruma: Shows consideration for Yan Si by stopping Hirako and Kyōraku from pressuring him to drink.
• Gremmy and Yachiru: Their relationship is portrayed comedically. Gremmy is quiet, literal, and willing to entertain impractical solutions, while Yachiru is energetic, bossy, and convinced she should direct their journey.

Significant Themes

• Deception and hidden motives: Aizen’s polite request may conceal an attempt to test Yan Si, reflecting the broader danger of trusting appearances.
• The limits of perception: Kyōka Suigetsu’s complete hypnosis makes sight itself dangerous and raises the problem of distinguishing reality from illusion.
• Strategic restraint: Yan Si survives the encounter by refusing neither too quickly nor too openly. Delaying action becomes a form of self-defense.
• Identity and false appearances: Yan Si’s fabricated Shikai and Aizen’s misleading description of his own ability show how both characters conceal their true natures.
• Comedic contrast: The tense psychological conflict between Yan Si and Aizen is contrasted with the absurd, lighthearted scene of Gremmy and Yachiru getting lost.

Important Character Interactions

• Yan Si and Aizen: Their conversation is outwardly courteous but functions as a subtle contest of suspicion and manipulation. Aizen presses for access to Yan Si’s knowledge, while Yan Si carefully avoids revealing his awareness of Aizen’s danger.
• Yan Si, Hirako, and Kyōraku: At the banquet, the two captains tease Yan Si and try to make him drink, highlighting his discomfort and his need to maintain his controlled public persona.
• Yan Si and Kensei: Kensei intervenes on Yan Si’s behalf, providing unexpected support.
• Gremmy and Yachiru: Their argument over directions emphasizes Yachiru’s forceful personality and Gremmy’s detached, almost childlike logic.

Chapter Summary: “Delivery of the Underground Secret Base”

Key Plot Points and Events

• Siwei Yan returns to the Second Division’s laboratory after the recent Human World battle, where a Great Hollow had appeared.
• Urahara Kisuke greets him with exaggerated concern, claiming he had been worried about Yan’s safety. Yan immediately sees through the act, correctly guessing that Urahara was mainly worried about losing his financial sponsor.
• Yan gives Urahara 120,000 in royalties—forty percent of the agreed payment—and promises to provide the remainder with the following month’s income. Urahara becomes enthusiastic and begins planning which spiritual research materials and equipment to purchase.
• Yan asks about the secret location Urahara was preparing for him. Urahara reveals that its structure and spiritual-pressure concealment systems are complete.
• The two travel through secluded routes in Seireitei to a hidden cavern beneath the Hill of the Twin Executions.
• Urahara explains that the underground base is protected by:
  • Sealing mechanisms that isolate it from the outside world.
  • Walls treated with modified Killing intent stone to block spiritual power.
  • The natural Reiatsu field of the Hill of the Twin Executions, which further conceals activity.
• Yan inspects the cavern and confirms that it is spacious, well-lit, secure, and suitable for writing, training, and spiritual experimentation.

• Yan’s growing unease about Soul Society’s instability becomes clearer. He recognizes that recent events—including Aizen’s advancement, the Great Hollow incident, and noble conflicts—signal an approaching crisis. This motivates him to accelerate his training and strengthen his spiritual abilities.
• Urahara Kisuke is shown as both comically money-driven and highly capable. His excitement over the funding contrasts with his genuine—or at least partly genuine—concern for Yan. He demonstrates impressive technical skill by creating an advanced concealment facility and using political connections to obtain restricted materials.
• Urahara’s caution is emphasized: even after leaving, Yan suspects that he may have hidden surveillance or backup measures inside the cavern.

Significant Themes

• Trust and suspicion: Yan and Urahara cooperate closely, but their relationship is based on calculated, limited trust rather than complete confidence.
