Dice Arisugawa, alias "Dead or Alive," is a gambler who thrives on risk, wagering his life in adrenaline-fueled games. His reckless choices render him homeless, indebted, and reliant on others for survival, yet he fiercely prioritizes allies’ safety over personal profit.

Born to Otome Tohoten, leader of the Party of Words, and Mikado Asuka, Dice’s childhood fractured after his father’s arrest. Otome left him with the Arisugawa family, but he fled, cutting ties with her. Destitution drove him to gambling, where he earned infamy for life-or-death stakes. A high-stakes win granted him a Hypnosis Mic, though rap battles lost their allure—no opponent could match his unbeaten streak.

Near starvation once led him to Rio Mason Busujima, who offered food and funds without demands. This kindness forged a pattern: Dice returns for meals, while Rio dubs the support "battle funds," investing in their shared future.

Dice’s appearance mirrors his chaotic charm—blue half-mullet hair, fuchsia eyes edged with green, and sharp canines. He dons a gold-starred green parka, ripped jeans, and a die-shaped hairpiece with red tassels. His Hypnosis Mic mimics a slot machine, echoing his gambling ethos.

His rap skill, "Max Bet," harnesses chance through a slot machine mechanic. Despite his carefree demeanor, he hides musical prowess—mastery of piano and violin—though he prefers crafting tunes on grass whistles. His name blends kanji from his parents’ names, while sevens mark his birthday, height, weight, and solo song, threading through his identity.

He scoffs at wild plants, notably deriding Tokyo grass’s bitterness—a testament to his scrappy survivalism. Though estranged from Otome, he once bargained with her to protect Ramuda Amemura, hinting at unresolved ties. Across his journey, Dice straddles self-destruction and loyalty, his reckless exterior belied by sudden acts of responsibility toward his team.
