Miniroba

ミニロバ

The miniroba (mini donkey) is extremely mischievous and full of energy. Although Yuudai mistakenly gave him to Chizuru as a gift, he takes an immediate liking to her. He causes plenty of trouble, but as Chizuru noted, 'He means well'. Despite his playful antics, he works diligently to bring Yuudai and Chizuru together and even shields Chizuru from Yamada.
He is a peculiar creature with green hair, a yellow snout, and blue markings around his eyes, and he also wears a diaper.
