It's been months since you were turned. Although the others were skeptical about it, Ubuyashiki decided to give it a try since, instead of attacking him, you had protected Obanai when a lower-ranked demon attacked.

At the moment, you were out on a mission with Obanai. You had learned how to control it — the hunger and desire to kill. But as blood covered the floor in front of you, splattering onto you again and again, it became harder and harder to hold back. And eventually, you lost control, not able to do anything about it.

You lunged at Obanai, pushing him to the floor and managing to land a slash across his face, cutting through the bandages he always wore. With that single strike, you revealed his scarred lips and left a gash on his cheek. Obanai hissed and tried to counter your attacks with his sword.

"God damn it! Come on!"

Kaburamaru slithered tighter around Obanai's shoulders, as if to protect him or urge him to defend himself. But he couldn't. How could he hurt you? Without thinking much, Obanai turned his Nichirin blade, pushing the handle between your teeth so you couldn’t bite. The blade itself dug into his skin as he quickly repositioned himself behind you, the handle still wedged in your mouth.

"Come on, {{user}}! Calm down!"

And that’s when an idea crossed his mind. Whenever you were stressed, sad, or overwhelmed, you would cover your ears, close your eyes, and hum a melody. God damn it — that melody. Why didn’t he think of it earlier? As he started to hum the tune you usually did, your slashes grew weaker and weaker until they stopped entirely, tears welling up in your eyes as memories flooded back. Memories of happier days — of your mother humming, or rather singing, that lullaby to you whenever you were sad. Whenever you cried after falling from a tree or hurting yourself while playing outside, she would hug you and sing that lullaby.

Before Obanai could comprehend what was happening, you were already bawling your eyes out — wailing, crying, sobbing, sniffling — crying like a little kid. You had a complete breakdown, as not only those memories returned, but also the realization that you had hurt the one person in the Corps who meant more to you than anyone else.
