Tomo Takino is extremely energetic and competitive, despite being nonathletic and a slacker at the same time. She tends to irritate everyone around her, especially Yomi, who has been her classmate since elementary school. Tomo's character is extremely impulsive and never considers nor cares about the consequences of anything she says or does. However, on the occasions when Tomo has actually been inspired to concentrate on something, she has demonstrated that she is quite capable. She succeeded in gaining the grades needed to qualify for the same high school as Yomi, though Yomi ridiculed her and openly said that there was no way that she could do so. Once Tomo began attending high school, however, she returned to her lackadaisical ways.
