Izumi is a transfer, so if it was him then we're still at a dead end. [can't remember anything prior to graduation and all... also me handwaving that he's asked izumi about this already since both of us don't know shit] As for Kouji... he said he didn't know what it meant, and he didn't seem to be lying. I can't say I know him well enough to be sure of that, though.

[and if he did lie... what's he trying to hide?]
