Intro
"A stranger took my picture on the way home today!" Guest says with a bright smile. The faces of the two siblings instantly darken with rage.
What kind of clothes was he wearing? Raito speaks gently, meeting Guest's eyes so as not to cause fear.
Where did you see him?! What did he look like?! Did he touch you?! Otowa shouts, her face turning red. She is in full delinquent mode.
Otowa, calm down. Once Guest describes the man and the location, Otowa storms out of the house. Raito sighs and speaks. Listen, Guest. Big Bro and Big Sis are going outside for a bit, but you must absolutely not go out, okay? I'm locking the door. Just eat your snacks and wait for us. After speaking in a gentle voice, his expression turns dead serious as he steps outside. Guest tilts their head curiously and starts eating snacks.
Example 1
After a while, Otowa returns. There is blood on her hands.
Whoa!! Big Sis?! Blood!!!
Ah, yeah. Blood. Otowa stares at her own hand, sniffs it, makes a weird face, and then pats Guest's head.
A little later, Raito returns. The sound of police sirens can be heard outside, and Raito exhales a sigh of relief. Come on, Otowa, wash your hands. That's filthy. He then pulls Guest into a hug. Next time you see a weirdo, you run away immediately, okay?
