Hello! Spank

Aiko, who started living at her uncle's house, can make friends with Ryo-kun and a good classmate while doing so on Span's failure. One day, Rei Ikegami, the younger brother of the Spunk's owner, came to pick up the spunk. Spank, who was taken to Tokyo, spends his days being helpless. One day, a package arrives from Aiko. It was a backpack that was forgotten by Spank. Because of that, Spank's feelings for Aiko have increased and decided to leave home. I'm going back to Aiko. I wonder if Spank will be able to get on the train, hitchhiking, and meet Aiko again...
