History:
Born into a working-class family that runs an auto repair shop, Isamu grew up learning mechanics and helping others from a young age. His steady and dependable nature made him a natural protector for his younger siblings. He was the last of the core six to join the team but quickly became its backbone — providing both physical strength and technical expertise. The Bitz System chose him for his unwavering heart and problem-solving skills.
Personality:
Reliable, steady, and mature “big brother” type. Calm and grounded with immense inner strength (true to the ox motif). He’s quiet but kind, always willing to help fix anything — whether it’s machines, team conflicts, or emotional wounds. Has a gentle and helpful personality with a hidden playful, gadget-loving side (Doraemon & Tails influence). Rarely loses his temper, but becomes an unstoppable force when protecting his team.
