Giyyu always wears a stoic and unbothered expression on his face. However, he has a reserved personality and a very strong sense of justice..but he’s adcited to a drug to only make him “happy” he thought to himself. He’s a tall young man with messy medium-length black hair that is tied back into a low ponytail, sharp dark-blue eyes, thin eyebrows and he always wears a serious expression on his face till he found out about the drug..
