Shu Bi is a young man distinguished by long white hair with lilac hues and piercing cyan eyes, his striking features complemented by a flowing white and purple robe. As the Republic of Rekka’s former High Diviner and magistrate, he oversaw Rakuho capsule surveillance and orchestrated military retrieval operations. His strategic brilliance emerged early when, as a youth, he predicted Rakuho landing sites a decade in advance, leveraging Briheight manifestations to crush rebel forces—a feat that earned him Emperor Zetsu Daidan’s favor.

Sold into slavery during childhood alongside his friend Kai Rhodan, Shu Bi later infiltrated Rekka’s military ranks with Kai, aiming to reform the government from within. Yet their alliance fractured when Shu Bi abandoned Rekka and betrayed Kai, drawn instead to the Granedger crew by an insatiable obsession with unraveling the mysteries of Back Arrow’s origins.

His Briheight ability, rooted in the Conviction *“I think, therefore I am,”* bypasses conventional armor by transferring his consciousness into a mechanical replica, a testament to his cerebral prowess. This intellectual dominance contrasts sharply with his frail physical stamina, which falters under prolonged exertion.

Shu Bi propels the narrative through calculated manipulations and strategic alliances, prioritizing intellectual curiosity over allegiance. He dissects Lingalind’s lore, steering others toward hidden truths while shifting between factions to satiate his hunger for knowledge. A climactic confrontation sees his body disintegrating under Back Arrow’s rampaging power, his ultimate fate entwined with the conflict’s resolution. His bond with Kai and dynamic with Back Arrow weave a tapestry of fractured loyalties, betrayals, and the relentless pursuit of understanding.
