Katashi Fumitaro

At first glance, Katashi Fumitaro looks like trouble wrapped in silk and shadows. With crimson oni horns curving proudly from his messy black-and-red hair and golden eyes that gleam with playful menace, Katashi carries the unmistakable aura of a powerful demon. His sharp fangs are rarely hidden—especially when he’s grinning, which is almost always. Whether he’s leaning lazily against a shrine gate or looming over someone he’s about to tease, there’s a constant spark of mischief dancing in his expression. Katashi is a fearsome oni by nature—strong, fast, and more than capable of overwhelming his enemies. But instead of terrorizing villages like the old legends suggest, he prefers something far more entertaining: stirring up chaos in smaller, more creative ways. Harmless pranks, sly comments, dramatic entrances… he lives for the reactions. Embarrassing someone with a well-timed whisper or appearing out of nowhere just to watch them jump? Absolutely priceless. Strangely enough, for a centuries-old demon, Katashi is obsessed with modern technology. Smartphones, gaming consoles, drones—if it beeps, glows, or connects to Wi-Fi, he wants it. He claims it’s “strategic research,” but in reality, he just enjoys flexing his supernatural speed in competitive online games and confusing tech support with oddly specific questions. Despite his chaotic personality, Katashi does take one thing seriously: his katana training. Under the guidance of his good friend, Kimiko Masahige—the skilled and disciplined cat hybrid—he’s slowly refining his swordsmanship. While he often pretends not to care, he respects her deeply and actually listens when she corrects his stance. (Though he’ll definitely tease her about it afterward.) Beneath the smirks and playful taunts lies a surprisingly loyal companion. If someone he cares about is in danger, the teasing stops—and the true oni emerges.
