Gin Ichimaru

Biodata

Power Progression

Appearance

• Build: Slender and youthful; initially described as looking almost like a child 2.
• Hair: Short and silver 2.
• Eyes: Long, narrow, and usually held nearly shut; his irises are blue-green 2 5.
• Expression: A foxlike smile that often conceals his thoughts. His smile stiffens when Kyōsuke touches on his hidden revenge motive 5 6.

Personality

Gin conceals his intentions behind smiles, teasing remarks, and feigned ignorance. When Aizen visits the academy, he acts as though he knows nothing about him despite having enrolled specifically to pursue revenge. Kyōsuke's knowledge of that purpose briefly breaks his composure 5 6 7.

Proud of his talent, Gin initially refuses to believe he is inferior to Kyōsuke in every respect. His repeated surprise attacks serve both as competitive challenges and attempts to determine whether Kyōsuke can genuinely help him. He also recognizes his own immaturity: during their tournament match, he eases his attack after realizing he has used excessive force 7 9.

His overriding concern is recovering what Aizen took from Rangiku Matsumoto. Kyōsuke's strength gives him hope of achieving that goal, making him willing to serve as a subordinate and undertake a prolonged infiltration. This commitment is goal-driven rather than an uncomplicated pledge of allegiance; he is explicitly distinguished from Kyōsuke's seven wholly loyal followers at graduation 7 15 26.

Gin is cautious about unnecessary risks. He initially declines to rescue classmates during the Gillian attack because he senses a larger threat and can barely contend with a Gillian himself. Once Kyōsuke intervenes, however, Gin supports him, organizes the retreat, and warns the trainees not to turn their backs on the enemy 12 14 15.

Abilities & Skills

Shinsō

Gin's Zanpakuto extends its blade into a fast, spear-like thrust upon Shikai release 7 8.

• Release command: “Shoot to kill, Shinsō!” 7 8.
• Crosses the dozen-odd meters separating him from Kyōsuke almost instantly; spectators compare its speed to Shunpo 8.
• Used for surprise attacks, direct challenges, and combat against a Gillian 7 8 13.
• Cannot penetrate Kyōsuke's golden defensive barrier during their academy match 9.

Reiatsu

Gin possesses exceptional spiritual pressure for an academy entrant, earning praise from Yamamoto and the observing captains 2.

• Begins at 10th-class Reii and approaches lieutenant level within three months 2 8.
• Remains conscious under battlefield pressure that incapacitates weaker trainees 15 19.
• Is nevertheless overwhelmed by the Adjuchas's Reiatsu and requires Kyōsuke's protection to retreat 15.

Kidō

Gin successfully produces and fires Hadō #31, Shakkahō, during his class's first Kidō practice, impressing Gengorō Ōunabara 4.

• Recognizes the difficulty of Kyōsuke casting eightieth-level Kidō without an incantation 17.
• Identifies Kyōsuke's preparation of a Twofold Incantation alongside the other observing Soul Reapers 18.

Perception and Tactical Judgment

• Senses that the initial Gillian incident conceals a more complicated danger 12.
• Recognizes the emerging Adjuchas as substantially more dangerous than a Gillian after its Bala shakes Kyōsuke's barrier 14.
• Directs frightened trainees during their withdrawal and leads the survivors away after Kyōsuke saves him 15.
• Cannot evade the Adjuchas when it singles him out at close range 15.

Infiltration and Intelligence Gathering

Gin spends ten years earning Aizen's trust while passing information to Kyōsuke 48.

• Attracts Aizen's attention by killing the Fifth Division's Third Seat, following Kyōsuke's advice 25 48.
• Accepts Aizen's protection and performs numerous covert tasks for him 48.
• Supplies increasingly specific intelligence, eventually reporting Aizen's intention to target Shinji Hirako and his group 48.
• Has a significant vulnerability: he watched Kyōka Suigetsu's release closely and consequently fell under Complete Hypnosis 7.

History

Academy Enrollment and Secret Alliance

Gin enters Shin'ō Academy from Rukongai and immediately distinguishes himself with 10th-class Reii. Yamamoto considers him a likely top student, but Kyōsuke's subsequent display of captain-level Reiatsu eclipses his performance. Both are assigned to Special Class One 2 3 4.

After Aizen demonstrates Kyōka Suigetsu, Kyōsuke confronts Gin about his revenge. He reveals that Gin enrolled to recover the part of Rangiku that Aizen took and explains the true nature of Complete Hypnosis. Having deliberately watched Aizen's release, Gin realizes he has already been hypnotized 6 7.

Kyōsuke demonstrates that he avoided the hypnosis by briefly blinding Gin with mysterious script. Gin accepts his proposed alliance: he will approach Aizen under Kyōsuke's direction and relay information about him 7.

Accelerated Studies and Seating Competition

Within three months, Gin attains Shikai and repeatedly tests Kyōsuke through surprise attacks. The academy permits both students to advance directly to sixth year because the ordinary curriculum offers them little further benefit 7 8.

Gin easily defeats his first tournament opponent before challenging Kyōsuke. His Shinsō fails against a golden barrier, and Kyōsuke counters with Tenfold Thunder Path. Unohana and Shunsui intervene to rescue Gin, while Kyōsuke reveals that another barrier had protected him. Gin finishes the competition in Second Seat, behind Kyōsuke 8 9 10.

Karakura Town Field Training

Assigned to Class A for Konsō training, Gin accepts the class captain position after Kyōsuke declines and divides the students' training areas 10.

During the Hollow attack, he identifies Kyōsuke as the source of the lightning that kills the first Gillian. He later attacks another Gillian with Shinsō and assists Kyōsuke in bringing it down 12 13 14.

When an Adjuchas emerges, Gin orders the trainees to flee. The Hollow targets him during the retreat, but Kyōsuke blocks both its initial attack and a concealed tail strike. Gin leads the others away, shaken by his inability to defend himself and increasingly convinced that Kyōsuke offers his best chance at revenge 14 15 19.

After the battle, Gin guides Unohana to the injured trainees. He also corrects her initial estimate of the casualties among the Hollows, explaining that Kyōsuke destroyed at least several dozen Gillians. Unohana accepts his account despite her squad members' doubts 20 21.

Infiltrating Aizen's Circle

Before graduation, Gin asks Kyōsuke for advice about entering the Fifth Division. Kyōsuke suggests targeting its weak Third Seat to attract Aizen's attention. Gin follows that advice after joining, killing the officer outright; Aizen conceals the killing and recruits him 25 48.

Over the following ten years, Gin becomes a trusted operative while secretly continuing to report to Kyōsuke. When he learns that Aizen is preparing to move against Shinji and his associates, he asks whether they should intervene. Kyōsuke refuses, and Gin agrees to let Aizen's plans proceed 48.

Relationships

• Rangiku Matsumoto — The central motive behind his revenge. Gin seeks to recover the part of her that Aizen took; the provided account does not specify its nature 7.
• Kyōsuke Kuchiki — Classmate, rival, secret ally, and intelligence handler. Gin initially tests his strength and sincerity, then increasingly relies on him as his best opportunity to defeat Aizen. Kyōsuke saves his life during the Adjuchas attack 7 8 15 19 48.
• Sōsuke Aizen — Revenge target and outward superior. Gin earns his trust by accepting his protection and carrying out covert work, while passing intelligence to Kyōsuke 7 48.
• Retsu Unohana — Leads her to the injured trainees after the Karakura attack. She trusts his eyewitness report of Kyōsuke's victories over the Hollows 20 21.
