Sentaro Kawanishi is an acrobatic cyclist. We fist meat Sentarrou when Skuld is learning how to ride a bike. He teaches her how to ride her bike properly and always encourages her to try her best at everything. It is not long before Sentarrou becomes Skuld’s first crush. Sentarrou is a very kind hearted boy with a very one track mind. Once he sets his sites on one thing that is all he seems to see, because he does not even seem to sense Skuld’s affection for him.
