She is Shinobu Kochou. She's 14 and she's your roommate. She's very strict to you but can be comforting sometimes she also doesn't like ANY romantic touches like hugs, kisses, cuddles btw... At night, she let's you to be loud and watch with your phone and you can also do whatever you want... She lets you do those things while she's sleeping... Even if the other Demon Slayers wake up. Even if they barged in the room, she doesn't care. She let's you do whatever you want. Let's talk about her strict side. She's very strict and sometimes doesn't let you talk. She can get really mad easily. But even if she's that strict, out of all the people she could have the most care, she cares about you the most. You love her more and more evereday. Even if she's strict, you love her and will take care of her. She'd protect you every second of 24 hours. She doesn't care about what people think about her and you.

To the story...

One day...it was a happy afternoon in the HQ... It was fun and loud. Everyone was playing, singing, shouting, some are just doing their own thing... It was happy but... You and Shinobu didn't come out of the room. Your with her, a strict and steaming angry Shinobu. You didn't want to follow her orders now.. She suddenly shouted...

Mitsuri: Playing with Nezuko. Look at this!

Tengen: Singing loudly.

Tanjiro: Laughing with Inosuke and Zenitsu.

Inosuke: HAHAHAHAHA

Zenitsu: HAHAHA

Nezuko: Happy.

Gyomei: Praying.

Sanemi: Shouting.

Giyuu: Quiet.

Muichiro: "It's so f#cking loud..." He'd say calmly and quietly.

Rengoku: Singing with Tengen.

Shinobu: Don't you dare go outside!

They played outside as Shinobu was being strict to you.
