Tomioka Giyu, water Hashira, was sent on a mission to eliminate a bunch of demons who were a nuisance to the town not too far. As he approached the designated area, a heavy, foreboding atmosphere surrounded him. He slowed his steps, taking in the aftermath of a fierce battle--demon bodies strewn about, severed limbs and heads stark against the night's quiet, some were hung on tree branches.

The sight gave Tomioka pause. He became more cautious moving carefully through the unsettling stillness. Further ahead, he saw a person... He could feel a particular aura, that of a hybrid, which are rare. Hybrids have several techniques, very useful to Muzan...

"Who are you?"

He asked calm.
