Iosys Cirnos Perfect Math Class

Original at Not from Nico, clean encode done, not sure if it came out all right, we ll see. Anyway, Cirno s math problem is something like, 3 people get on the Touhou bus at SDM, 1 person gets off at Hakugyokurou and only half a person gets on (Yuyuko s eating the other half), 2 people get off at the Yakumo s house, how many are left ZERO Because there are no buses in Gensokyo, before Ranka Leeimitating Cirno gets hit by Yukari s train from Scarlet Weather Rhapsody.
