MegaGamers is in Akihabira. Thats a long walk from Kichioji. Piro needed a rail pass so he can get to work on time (remember, he had been wandering around tokyo when he ran into Yuki again)
actually, he ripped a pocket off - the dashed lines where his left pocket used to be didnt come out very well, unless you look close.
FYI, this is a spoof on something that actually did happen to me around the time i met seraphim - i stood up and caught the my pocket on the edge of something and rippoed the pocket half off. ^_^
