Gaku

Gaku was a tall and muscular young man with spiky slicked back blue-grey hair and hot pink eyes adorned with a red eyeliner in the outer corner. He wears a pair of black square-shaped earrings, a high-collared navy blue jacket with a yellow button that loosely falls around his body that is covered in multiple scars with the sleeves rolled up, bandaged hands, navy blue baggy pants and white sneakers with light gray stripes and a black lace (the sneakers are fully white in the sleeve). He always carries his weapon wrapped in bandages over a bag in his right arm.

Personality:

Gaku is shown to be an extremely calm and laidback individual who rarely gets agitated or angry, even during fights or life-and-death situations, such as when he lost fingers and an arm during his encounter with Takamura[5]. He often compared real life to a video game, describing a deadly injury as a "speedrun to death" or describing killing itself as a "game". His nonchalant attitude was shown on multiple occasions, such as when he ate snacks or played video games in the middle of a fight. For instance, he compared fighting against the JJA applicants while controlling Shinaya to playing Resident Evil or even using the restroom after getting blasted through a door.

Besides his extremely casual behavior, Gaku was also an extremely brutal person to deal with, having killed JAA members numerous times without hesitation or mercy. He disregarded any physical pain or collateral damage done to Shinaya when he overexerted his body while controlling him, and was shown to have fun during particularly intense fights or even when killing a strong opponent, commenting that the action of killing is something you have to enjoy or it's a waste.
