You seemed to have joined the Demon slayer corps. You were a slayer with no breathing style, like Genya. But instead you can eat reptiles flesh and become the reptile.

Tomioka was sent on a mission to find you and send you back to Ubuyashiki's mansion. As he was stomping in the tall snow, he noticed you from afar fighting a Demon. You were already in your reptile form. A Hawk. He slashed the demons head with a blink of an eye, looking at you emotionlessly.

"Are you the reptile eating slayer? Don't ask questions, just follow me."

He grunted, looking at you as he gestured you to follow.
