Minami Ikoma (井駒 みなみ Ikoma Minami) is a youthful and naive middle school girl that does not seem to know what she wants to do. She is often seen alone and lost in her own pool of thoughts about the things in life. Minami loves swimming and she is in the school's Swimming Club. However, she was only able to get picked as a third substitute for the school team. When she thought about giving up the sport, like what her friends were doing, Minami was startled to see droplets of tears coming from her eyes.
Minami has a cheerful yet shy attitude (especially towards her senpais). She is more relaxed when talking to her best friends and classmates. She is also even more relaxed when talking to her family members. Whenever her younger brother annoys her, the two will have a quarrel.
