B Saibou

Clad in a blue-grey jumpsuit and wielding an oversized spray gun, this teenage lymphocyte plays a pivotal role in the body's defense network as a dedicated antibody producer. Though his personality leans toward the boastful side, beneath that bravado lies a deep craving for recognition. He specializes in handling pathogens that ordinary immune cells struggle to defeat, relying on intelligence passed down by memory cells to launch precise counterattacks. His clashes with mast cells over jurisdictional duties are a recurring source of friction.
