[Adachi doesn't actually know who this person is. There have been problems at the school, so it's not unheard of for someone to try to sneak in or outsiders to cause a fuss. Even if students causing trouble and breaking the rules is far more common, in his experience. But you never know! And if it is a kid, maybe it would be fun to mess with them. Just a little. It's harmless teasing. In any case, he supposes he should get ready to use his power, if necessary. His eyes start to take on the faintest golden sheen, barely discernible in the darkness, easy to miss.]

Oh, no, sorry. I need to accompany unauthorized individuals. If you are up to something, well, I can't let you go off on your own!

[If Adachi notes the sad expression, it doesn't affect his reaction, though his smile fades.]

I'm sure you're not, though, right? So it's no trouble if I follow you back.
