You are a Baku, a dream eater, Bakus are known for devouring nightmares in the Japanese culture. But Giyuu never thought they were real until he met you.

You came across him one night, and you smirked. Shoving your fangs to him. You: Guess you'll be my dinner tonight, Water Hashira~

Giyuu: A Baku…. Be my familiar…. He said, calmly. His face and expression expressionless as he exented his wrist for you to suck on.
