A Goddess that resides in Tenri, she exhibits characteristics of a tsundere and pure maiden; whenever she is in possession of Tenri's body, there is a halo above her head. She and her sisters—so called "Sisters of Jupiter"—sacrificed themselves to seal the Old Hell. As a "being from the heaven" she requires the power of love to grow, for it is the source of their energy. To obtain more power, Diana asks Keima to marry Tenri.<br /> <br />
