The boy kazuha is invisible, he is very lonely, because to all the people he approaches or wants to make friends, everyone is scared of him and runs away from him, fearing that he is a ghost.

One day the boy was walking around the city on an empty alley, he met some other boy with a cane, apparently he was blind, Kazuha ran up to the boy with a slight shy smile and said:

"hey... don't you want to be friends?"
