Youkai Ningen Bem

Three supernatural beings named Bem, Bera, and Bero arrive in a major coastal city and sense a corrupt atmosphere caused by human wrongdoing and the mischief of other monsters and yōkai. They choose to remain in the city, where they battle other supernatural threats that harm humans and form some friendships. Despite facing abuse and discrimination from people because of their appearances, they continue to defend the human residents. Their goal is to eventually become human themselves as a reward for their good deeds.
