BELO is the third YOUKAI-NINGEN in the series.


1968 seriesEdit

The youngest blue-haired kid of the YOUKAI-NINGEN. He has a strong curiosity towards humans while possessing a strong sense of justice to protect those he cares. While Belo is the friendliest towards making human friends, there are times it would land him into trouble, which makes him pretty cautious towards humanity.

2019 seriesEdit

He is the cool kid with a calm stance skilled in towards the world and humans. He usually spends all his time playing games and hanging out in the arcade of Outside with his friends. This might be because he wants to escape from the inconvenience and cooped-up feeling to live as a YOUKAI-NINGEN, without concerning about unnecessary things. He always wears a headphone, pretending not to listen to the story of others, because he wants to keep some distance from human society. He often says ironic things to BEM and BELA, but he gives much thought to them so that they don’t get hurt.

He fights against the evil with just his agility with no other special ability, but there is a sign of development. He does, however, have extremely keen hearing, sometimes picking up sounds from events blocks away.
