As mentioned by her sister, Akine, Manatsu loves making other people below her. Growing up, Manatsu enjoyed comparing herself to her sister who was unattractive in the eyes of people. Seeing Koyuki being loved by the captain despite being a beginner in basketball in middle school, she grew jealousy. The moment the captain graduated, she started backstabbing and bullying Koyuki to the point of her leaving the team.
Manatsu also looks up to her upper classmen, Tatsu, who was one of the bullies of Koyuki.
