"Um..." Keiichi looked somewhere between confused and even more confused than usual. "Sonozaki-san and I probably haven't spoken more than a few sentences to each other here and there until the past few days."
And then, he remembered something.
"Oh, that's right. I didn't tell you quite how I ended up in Paradise, did I??" Pausing a moment, Keiichi frowned. "She hadn't been around at all for days. Usually I at least see her in the cafeteria in the dorms. So I decided to go see if I could find her. It...ended up being her shadow. I meant to call you all, but I left my phone in the room. I attempted to get it to tell me where Renju was, and it, well, showed me. After kicking me in the groin and knocking me out."
Damned cowardly shadow (that could have exploded him into a frozen pile of organs and skin).
