Ikaros loves petting round things, especially watermelons, she even has a farm full of them. Even when Tomoki tried to take a watermelon from her to consume it, she refused to give it up and kept it for herself.

She begins the series with a poor grasp of human emotion, but after Nymph tries to unlock her memory to make her realize she isn’t a “Pet-Class Angeloid”. Ikaros’ memories on “Self-Repair” is also unlocked and she quickly unlocks the rest of the restraints put upon her, making her weapons and emotions effective.

She was originally sent to Earth as a weapon of judgment and was responsible for destroying The Tower of Babel.
