Atsumi is an energetic girl who loves the female body. She enjoys foods like soft buns and has become an idol to make friends with other girls. While she's not shy about what she likes, she controls herself enough not to grab her companions without consent. When describing other women, Atsumi can be quite perverse and often stares at the bodies of other idols. Her attention span decreases as the number of beautiful females around her increases. During the Hawaiian Beach event, Atsumi brought a camera and was part of an idol group. She often comes up with ideas to touch other idols' breasts, although she has gone overboard on occasion. Some idols have used this against her, such as Helen and Manami Kiba. In Cinderella Girls Theater skits, Atsumi promotes skinship with her fellow idols. During a daydreaming frenzy, Manami Kiba drew Atsumi out of it by placing her on her lap and under her own cleavage. Atsumi tries to get other idols' permission to touch their breasts using tactics like acting like a little sister and bribery. She can be easily distracted by breasts, using other objects like food to satisfy her desires.
