Despite not being athletic or a hard worker, Tomo Takino is very energetic and competitive. She often irritates those around her, particularly Yomi, who has known her since elementary school. Tomos behavior is impulsive, and she doesn't consider the consequences of her actions. However, when motivated, Tomo has shown that she can be quite capable. Despite Yomis initial skepticism, Tomo managed to gain the necessary grades to attend the same high school as Yomi. After starting high school, however, Tomos returned to her lazy habits.
