Note: There is a lot of private and elementary school writing. The male protagonist is the King of Bones. The original heroine Albesh [note that it is not Albedo! ! Albedo is closely related to the heroine] One of the forty-one supreme beings, her race is a draconian [alien species] and can transform into a dragon. Maybe it involves other anime occasionally... There is a slight lily tendency. There are more plots where the female protagonist takes the initiative [I personally prefer the female protagonist to attack the male protagonist], but the Bone King is still very tough when he should be tough. The plot should be magically modified. The senior high school party is updated by chance.
