Spoiler for chap 4:
WTH? JTouma CAN'T be THAT physically strong to knock him down in one blow, could he? Of course they left it off on a cliffhanger, but from how the enemy was looking, he's seriously hurt, if not knocked out already:
I guess he wasn't BS'ing about NOT beating those guys up earlier.
I re-read the chaps again, and a question came to mind(particularly aimed at s_b since s/he read the Railgun manga). Why would Mikoto attack Touma(ch 1), even though he was running away from those thugs? Initially, he shows no abilities whatsoever, i would think she sees him as some coward, and not worth her time, yet she uses a powerful move on him right off the bat. Doesn't make any sense to me.
