|Nickname:||Alpha, Uranus Queen|
Since she began living with Tomoki, she has become somewhat of a live-in maid where she is the one that cooks breakfast, lunch, dinner, wakes up Tomoki in the morning, and otherwise takes care of the house. While she begins the series with a poor grasp of human emotion, she eventually begins to acquire emotions and begins to fall in love with Tomoki. The reason for this is because she has high battle and processing capability, but has low emotional control as a result. She has been shown to be willing to sacrifice herself if it means ensuring the safety of Tomoki.
Ikaros is also shown to do anything that will gain Tomoki's approval, even if it's a questionable act (normally involving Tomoki's perverted schemes) on Tomoki's part; she admits that as long as Tomoki is happy, she will also be happy as well. In one chapter, she became extremely depressed when Tomoki broke the imprinting between them and finds it difficult to express her feelings (Mikako notes that Ikaros has difficulty being open with her emotions involving Tomoki unless his life is in danger) until she was ordered to throw Tomoki into the ocean. This puts enough emotional stress on her that she tearfully begs Tomoki not to throw her away.[volume & issue needed] She loves when Tomoki pats her on the head, and even becomes depressed when he is unable to do it. She is noticeably the only girl in the series that Tomoki does not sexually harass in any way.
