"...I... ...I... love you... Aijou... I didn't know... love... could be so warm..." Kogoe is extremely sensitive to cold, to the point of being barely able to function if she feels chilly. Due to her sanpaku eyes, most people believe that she is unfriendly, and she was a loner throughout most of middle school into her first year at Ohananomitsu High. However, Kogoe is actually very kind and sociable, albeit somewhat reserved. Since speaking up causes her to lose body heat through her mouth, and she is not very good at explaining that she was born with sanpaku eyes, Kogoe does not talk loudly or often. She was able to mix in well with the other members of the Rentaro Family after being introduced to them. Kogoe has dark gray eyes, and long gray hair which reaches her mid-back. She is slightly shorter than Rentarou, and has a slim figure. Her most distinctive features are her sanpaku[1] eyes. These gave her a piercing gaze, which caused many people to feel uncomfortable when making eye contact with her. Kogoe initially grew her bangs longer, in order to conceal her eyes and avoid intimidating people. After meeting Rentarou and becoming his girlfriend, Kogoe trimmed her bangs to reveal both of her eyes.
