Komaru

The sister of the Ultimate Lucky Students had felt a bit insecure at times. Because of Makoto being an Ultimate, she often would hang out with them too and being one of the only two people there without an Ultimate Talent made her feel a bit insecure...

Though the more time she spent with them, the less insecure she felt. They even started joking around and calling her the Ultimate Sister. Things especially got better after she started dating Toko Fukawa.
