Kaede Manyuda holds the treasurer position within the Hyakkaou Private Academy Student Council. Driven by his father's ambitions, he seeks the presidency to overthrow Kirari Momobami. Tall and slender with pale skin and dark eyes, he initially possesses well-kept black hair. After a traumatic gambling defeat, his hair turns completely white. He consistently wears black-framed glasses and the standard Hyakkaou uniform: a red blazer with black trim, white dress shirt, black tie, and plaid trousers. His personality blends cold calculation with deep-seated insecurities. He operates with ruthless observation and strategy, preferring the "high road" in gambling to minimize risk and predict opponents. He harbors intense fear of being perceived as worthless and discarded, a trait mirrored in Itsuki Sumeragi. Following his defeat, he sinks into profound apathy, viewing life as meaningless, though high-stakes games later rekindle some spirit. His story begins with manipulating council dynamics, recommending Itsuki Sumeragi for membership while privately scorning her. He engineers gambling events, including Yumemi Yumemite's match against Yumeko Jabami. Falsely accused of sabotage during Yumemi's loss, he publicly declares his presidential bid. Forced into a Choice Poker match against Yumeko, he initially dominates by exploiting her tendencies and belittling Itsuki. The climax reveals Kirari Momobami as the disguised dealer. After betting his life and losing to Yumeko's unexpected three-of-a-kind, Kirari dismisses him with "You're fired." The shock turns his hair white and lands him in the hospital. Post-defeat, Itsuki Sumeragi cares for him using the life plan relinquished by Yumeko. He remains despondent until Yumeko recruits him for the Greater Good Game. During this event, he collaborates with her to feign betrayal, forcing other players to pay maximum taxes. He deduces the true traitors (Itsuki and Miroslava) and shows concern when Miroslava attacks Itsuki. Finishing in fourth place with no net gain, he is unsettled by Itsuki's secret bet to restore his spirit, forcing him to acknowledge her conflicted feelings. Later, he expresses dismay learning of Yumeko's temporary abandonment of gambling. In the *Kakegurui (Kakkokari)* spin-off, his serious demeanor contrasts with occasional perverted thoughts, like misinterpreting Midari Ikishima's praise of Yumeko as sexual. His hair remains white after Chapter 129. Regarding relationships, he initially scorns Itsuki Sumeragi for lacking talent but develops empathy over their shared fear of failure. Despite underestimating her, he later worries for her safety during the Greater Good Game. Itsuki reciprocates with covert affection, betting to reignite his spirit. He respects Yumeko Jabami's abilities yet views her as a pawn for his ambitions; she ultimately exploits his predictable "high road" strategy to defeat him. His dynamic with Kirari Momobami is purely adversarial; he aspires to dethrone her, while she remains indifferent until decisively removing him from power.
