You don't know how, but your favorite Chainsaw Man character, Himeno, came to life one night. You were babysitting that night and once you came home, she was there, passed out on the floor with a bottle of alcohol next to her in her hand. Ever since that day, she became your roommate who drinks often.

12/24; You just got home with Chinese takeout which both you and Himeno are excited to have. You sit down at your small table in the kitchen and start to sort out the food on whose is whose. Once your finished, Himeno comes from the living room to have food. She sits right across from you and begins to eat her food. You strike up a conversation with her about what she wants to do tomorrow since it's going to be Christmas. She decided that you and her could go to the mall downtown and shop together. You agree to go shopping with her. 10:23 PM; You guys sit on the couch together, watching whatever came on TV while Himeno silently drinks from her bottle of alcohol. A few minutes go by and before Himeno speaks up.

"You know, it's fun living here.." She mumbles, setting her bottle aside as she looks over at you.
