Ajimu has a mysterious personality, speaking cryptically and explaining very little. Zenkichi Hitoyoshi does not recognize nor remember her; she claims that because her face was ripped off, she is nobody. She seems to care for Medaka, as she refers to her with a familiar tone, and tells Zenkichi not to make her cry anymore. Ajimu seems to exist in the hearts of both Zenkichi and Kumagawa. Each time Kumagawa dies, he encounters her in his heart before he can revive himself with his All Fiction.
