[ Rin did indeed pick out the tobacco (nice but not too nice because she knows Gen likes the cheap stuff) and roll it up herself. Just one of the many miscellaneous talents of Tohsaka Rin. Maybe there's a pile of less-than-perfect practice cigarettes lying around somewhere — or maybe not, since that would be a waste of money.

Please... keep this with you, even if it's just the case.
