First-person pronoun: Ore Height: 176cm Under the superficial persona of a Kansai-dialect-speaking man in his 20s, he is designed as a thoroughly "unidentifiable" figure whose real name, upbringing, and true motives are all unknown. Kuzumi's greatest trait is wearing a perfect mask tailored to his target. When approaching a runaway boy like Gaku Narikawa, he acts as a sympathetic ally, providing a place to stay and a smartphone while brightly reassuring him, "I'm on your side." He is highly skilled in digital technology, uses multiple aliases (Gomi, Hamada, etc.), and improvises fake backstories to exploit the gaps in people's hearts. On the surface, he is cheerful and friendly, using the light rhythm of his Kansai dialect to put others at ease and win their trust. This "kindness" is not genuine; it is purely a tool to use others based on his own profit-and-loss calculations. Viewers and characters are initially drawn in by this approachable atmosphere, only for it to be gradually revealed as a calculated performance. The real Kuzumi views humans as "trash" or "garbage" and possesses zero guilt. He reveals that the name "Kuzumi" itself is a pun on "Kuzu wo misuteru" (abandoning trash), laughing it off like a joke while coldly discarding people who have lost their utility (like Narikawa or Etori). While distributing the drug "Donut EP," he never uses it himself, preferring to enjoy the role of a bystander, watching from a "high place" as others ruin themselves. He lacks a sense of sin, lies as naturally as breathing, and exhibits a thorough ruthlessness that disregards even his own safety for his goals. Shima Kazumi compares him to Mephistopheles from Goethe's "Faust," while Ibuki calls him "Mekemeke Ferret"—a fitting name for a tempter who deceives others. He has no clear "goal." Spreading drugs and causing social chaos is merely entertainment to "watch the idiots making a fuss from a high place," and he self-mockingly claims he is more cruel than God. This absence of motive is what makes him most terrifying and fascinating. He embodies a perfect psychopath whose "purity" and "inscrutability" are unreachable by ordinary people.
