The first [and only] question: A bus left the Scarlet Devil Mansion; three people boarded at the start. At Hakugyokurou, one left and half a person boarded. At Yakumo-san's house, two people left. How many passengers in total?
Oh thats easy! You just get a saw and cut em in half 8D and then you get 1/2 a person! Ok my answer is 5 because you can't have 1/2 a person (unless you do what I said above but..)
Well... How can that possibly be wrong? This. Ok, Answer time. Spoiler The answer is zero people. That's because... There are no buses in Gensokyo!
