He has a cheerful personality at first glance but is actually someone who has a very deep obsession over his daughter's well being. He has sharp insight on the flow of battle and is not afraid to take immediate actions for situations he thinks to be appropriate.
Atui - His daughter whom he loves very much. He is very overprotective of her, especially when it comes to finding a suitable partner.
Haku - He didn't quite like the young man at first glance, coupled with misunderstanding that stems from misinformation and would be seen chasing him everywhere just to squeeze as much information about his relationship with Atui. When he meets Haku again when he is impersonating Oshutoru, Soyankekuru actually believes that Oshutoru is a good match for his lovely daughter without ever realizing the man in front of him is the same man he had terrorized in the past.
