Second-year classmate of Mitsumi Iwakura and a member of the Drama Club. He's very strong-willed and passionate about his interests, especially acting. He has shown to be very willing to put in lots of time and work into what he loves, and doesn't hesitate to drag others into it. His love for acting, and his will to share it with everyone does somewhat blind him from seeing other's emotions on the other hand. Despite being somewhat oblivious to emotions at times, he always helps others and cares about their wellbeing. Narumi dreams of becoming a playwright in the future.
