A young man with amnesia. He is currently living at Hiyori’s sister’s house as a foster child. Not knowing about the normal world, he’s rather my-pace (air-headed, lost). In his spare time, he plays baseball with the neighborhood children. He is known to possess a strong curiosity for the unknown. His favorite animal is the triceratop and likes BBQ. He looks like a brother to Hiyori and Hibiya and is always with them.
