Nara is a student in the tenmas class who often goes unnoticed by others. despite this, he harbors feelings of love for tenma and finds it easy to communicate with him. however, his interactions with harima are limited due to her presence, as she tends to dominate social situations. additionally, nara's small stature makes him feel intimidated when in the presence of someone like harima, causing him to back down whenever possible.
