Moe Shishigawara

A high school boy with a delinquent appearance, attending Miyashita Commercial High School.

He refers to himself as "I" and considers himself a subordinate to Tsukishima, motivated by inexplicable but unfaltering loyalty—a true delinquent's temperament.

He confronts Orihime before Tsukishima can make his move, but is utterly overwhelmed by Orihime's cuteness, known to her (and by Chad in the anime version) as "Mr. Shishigawara."

Ginjo has been wary of his abilities long before his true nature was revealed, and even after joining the same side, Ginjo warned Tsukishima about Shishigawara with instructions not to share the Fullbring techniques with Ichigo and to stay cautious of him. Furthermore, Shishigawara was unaware of the weakness in his Fullbring abilities that drew too many hits early in the fight, leading to a diminished effectiveness as the fight went on.

In the final battle with the Shinigami, he fights Ikkaku and initially overwhelms him with his Fullbring powers. However, the flaws in his abilities eventually surface, leading to a bare-knuckle brawl with Ikkaku, and ultimately his defeat. Despite this, he attempts to continue fighting for Tsukishima, but is stopped by Ikkaku questioning if Tsukishima is truly worth dying for, and is sharply rebuked.

After his defeat, he meets with Tsukishima and, realizing he's been treated merely as a tool, he carries Tsukishima and walks with him to help, admiring him to the end (Tsukishima dies peacefully, saved by this gesture).

In the final arc, like Jackie, he does not appear much unlike the other members.

In the novel, it's mentioned by Yukio that he built a grave for Tsukishima and visited it.

Fullbring: "Jackpot Knuckle"

Activated with a knuckleduster featuring the design of triple sevens on his right hand, this ability manipulates "probability" to force out jackpot results immediately, effectively harnessing luck. This turns even low-power strikes into critical hits capable of causing massive damage due to "lucky" coincidences, potentially making any hit lethal.

However, the manipulation only skews the probabilities, not increasing the frequency of hits—the inevitable jackpots are merely pulled forward, which does not increase their number. Thus, in prolonged fights or with excessive use, the ability inevitably struggles to pull jackpots later on.
