[that gets a hum. even though Rin hadn't seemed any different from the rest of them, "robot" is a little beyond Kaoru's time.]

I am afraid that I know nothing of what Miss Kagamine is. I fear any speculations I might have may be incorrect, accordingly... But I believe that it at least helps to know a rough time frame. Between 3:00 and 3:30, both Miss Sto Helit and Miss Aozaki do not have strong alibis, unless someone spotted either of them. Likewise, Mr. Tanaka has twenty minutes unaccounted for and claims to be in the place least likely for anyone else to corroborate.
