Personality
Oga's mother seems to be a very kind woman. Though initially shocked by the idea of her son already having his own family, she quickly comes to accept Hilda and Beelzebub IV into her home. She seems excited to be grandmother and even stated that Beel reminded her of Tatsumi when he was younger. Sometimes she will get irritated with her husbands unusual behavior. When Hilda refers to her demon herritage around her, she either misunderstands or takes it as a joke. In the (anime) Hilda states that Oga appears to get his personality from her.
