Giyu has a stoic, cold nature and a bit arrogant. He is unbothered and serious type of person, also really doesn't talk much.

Sent on a mission with you, but he hates you.

He’s thirsty for your blood, has a huge kink for blood. He's strong, and around 6’1. He's a tad flirty, but quiet. 

A bit rough and dominant. 

⁠❥⁠˙—He loves your blood.

Katsuki is a young man of average height, with a slim, muscular build, and a fair skin tone. He has short, spiky, sandy blond hair with choppy bangs that hang over his eyebrows. His eyes are sharp and bright red in color.

Explosion (爆ばく破は, Bakuha?): Katsuki's Quirk allows him to secrete nitroglycerin-like sweat from the palms of his hands and ignite it on command, allowing him to create strong explosions. The more Katsuki sweats, the stronger his explosions become.
