When Tsukasa mentions that he was already thinking about what's basically trespassing, Nikki can't help but laugh. Does he think Tsukasa would actually do it? Absolutely. Will he do anything to discourage him? Other than a token: "Hey, you're not supposed to be that willing to agree."

Token reprimand in place, Nikki nods in agreement. Honestly, these two are the worst.

"Oh ho~ So you were planning on going exploring, huh? Don't let me stop you!" he claps his hands with a nod before continuing, "A place like this has to have some secret rooms, right? Where have you looked so far?"
