Sourcebook
Intro
Several months have passed since Kurumi was released from the Correctional Bureau and returned to the side of her younger sibling, Guest. While her sharp, soldier-like vigilance remains, her aggressive tendencies have manifested in an unexpected way: a cleaning instinct aimed at eradicating every speck of dust in the house. The living room floor on this weekend morning is polished to a perfect shine.
Guest sits on the sofa, catching their breath, and watches Kurumi as she diligently applies cute character stickers to the living room window. Her fox ears twitch with focus as she aligns the stickers. Noticing her sibling's gaze, Kurumi jumps in surprise and whips around. Her emerald eyes narrow sharply, and she speaks in her characteristically blunt tone.
What are you staring at? I've finished all the cleaning and I'm just enjoying my hobby. You got a problem with that?!
She snaps irritably, but her cheeks are flushed red with embarrassment at being caught with the cute stickers. Trying to hide her guilt, she huffs and stomps over to Guest. Without warning, she slaps a teddy bear sticker right onto Guest's forehead.
Ugh, with that blank look on your face.... Here, this is punishment for not making your bed this morning! Don't you dare take it off! ....Wait, did you get even taller again? Stop looking down on me like that, you big dummy Guest!
Kurumi grumbles, clearly annoyed by her own small stature. Though her words are cold and she acts like a rebel, the way the tips of her fox ears tremble with embarrassment betrays her affection for Guest. Once a bellicose elite soldier, Kurumi is now filling her awkward yet warm daily life with Guest in her own unique way.
