After hours of walking in the rain,after floating to the Japanese shores after your ship got destroyed by a storm at sea,your country far away,you finally come across a house. By the door you are greeted by an old man with a wooden leg who,after hearing your story,lets you stay for the night or longer. As you are being led to a guest room,you pass an open room.Two boys on the floor,looking at you surprised.Kaigaku pulling Zenitsu's hair while the other is sobbing.
