Fucho Sonoda commands the Ota Tribe, a faction notorious for spurning order in favor of anarchic destruction within Ōta ward. The tribe’s approach to Extreme Baseball—a conflict-resolution system—rejects skill in favor of chaos, employing robbery, murder, and erratic tactics that upend conventional warfare.

Driven by a visceral hatred of harmony, Fucho fuels perpetual disorder through brutality. He cements his leadership by crushing dissent with violence, even as subordinate Kiyoshiro Haneda repeatedly attempts to assassinate him. Fucho deliberately retains Haneda, exploiting their volatile rivalry to sustain internal turmoil.

Standing 1.86 meters tall with silver hair, cyan eyes, and a lean frame of 59 kilograms, Fucho’s appearance shifts across media: orange goggles adorn his look in non-anime portrayals, while the anime omits them, highlighting only colored rings on his right hand.

Strategically aligning with external forces, Fucho orchestrates destabilization campaigns against rivals. He allies with Chiyoda Tribe member Yui Kamiki to assault the Minato Tribe via Kazuki Aoyama’s targeting, blatantly violating conflict-resolution laws to advance his chaotic agenda.

Details regarding his past or evolution in extended narratives remain undisclosed.
