Zanmu is described as the perfect oni according to Suika. She has both the strength and intelligence that an oni should be portraying. That said she is also seen to have a sense of grace, seeking a (relatively) peaceful resolution to the beast wars and to protect Gensokyo from destruction. In this sense, she shares much in common with Reimu, feeling a sense of communality. Zanmu is not easily upset. She frequently forgives her bumbling assistant, Hisami.
