Description
Manabu Oizumi, the theatrically inclined student council president of Kadode Middle School, embodies narcissism through his flair for transforming card battles into grandiose spectacles. His sharp appearance—short wavy brown hair, glasses, and a dark blue-purple jacket over a light purple shirt—complements his dramatic persona. Initially wielding a red-green Brave deck mirroring Dan Bashin’s legacy, he pivots to a blue deck anchored by X-rare powerhouses like *The SunDragonDeity Rising-Apollodragon* and *The IronHero Saigord-Golem*.

His competitive arc opens with a debut loss to Tegamaru, but he rebounds by defeating school principal Keisuke Saimon in the Hero Championship’s red block, advancing as a finalist alongside Kimari and Tegamaru. At nationals, he secures a world tournament berth, declaring ambitions to become the "student council president of the world." His momentum halts in the D block finals against Renard, a British duelist prioritizing chivalric discipline.

Manabu’s younger brother, Kataru, idolizes him fervently, even crafting celebratory "special water" for his victories. This admiration curdles into rivalry as Kataru vows to surpass him in future tournaments. Post-series, Manabu inherits followers once loyal to Chihiro, sparking friction between Kataru and these newfound devotees.

A natural showman, Manabu commands crowds mid-battle, punctuating strategies with sips of mineral water. His presidential authority allows him to summon peers for impromptu discussions, though his administrative duties remain undefined.

Deck evolution mirrors his growth: abandoning imitation for a blue-centric strategy, he wields spirits like *The GiantJaeger Orion* and *The RoaringArm Todon*, supported by burst magics such as *Sealing Maelstrom* and *Swallow Counter*. His playstyle prioritizes control via nexus cards like *The Port of Giants* and *The Giant's Stamp Lake*, blending defensive tactics with calculated aggression.

His narrative threads explore forging originality in deck-building, reconciling sibling rivalry, and weathering defeats without shedding his performative charisma.
