Miniroba

The miniroba (mini donkey) is very naughty and has a lot of energy. He was mistakenly given to Chizuru as a present from Yuudai, but he takes an immediate liking to Chizuru. He causes lots of trouble, but as Chizuru said, 'He means well'. Despite his mischievous nature, he works very hard to bring Yuudai and Chizuru together and even protects Chizuru from Yamada.
He is a very strange animal with green hair, a yellow snout and blue around his eyes, and he also wears a diaper.
