Chocolat and Vanilla are asked to take the day's homework to their classmate Akira, who's off with a cold. When they get there they discover he's not ill, but skipped school to search for his missing dog Hiroshi. Chocolat organizes a search party, and,with the help of some magic, eventually locates Hiroshi, who was waiting at the harbour for Akira's father's boat to come in. Akira thanks Chocolat for her help, and his heart turns Green with friendship. Chocolat takes it, and muses that she appreciates it more than any other heart she's collected so far.
