This may suggest that they were intended to be befriendable, and the idea was scrapped and reused in Yo-kai Watch 2: Psychic Specters.

Anyway here’s my take on the 4 oni siblings design! Yeah Orcanos is a tall buff woman, you’re welcome!

Osomatsu was growing fond of this lday~ she didn’t say very long but when she dropped by his den it was always a good time. He growled low in his throat as he trailed down Ellie’s pale skin, leaving little hickys with his sharp teeth.

Oso has only seen one female oni in his life; his mother. She-oni’s are very hard to come by.
