Sumie Ayado (綾戸 純恵 Ayado Sumie) is an otaku girl who fell in love with Hikari Tsutsui due to their similar interests and because he got too close to her.


Sumiye was born to two easygoing and loving parents who encouraged her to pursue any interest she liked. Her life was normal and peaceful until she fell in love with anime and manga, even developing a crush on a hero in a story. However, when she told her friends about it, they began shunning her. As more people ridiculed her hobby, she began retreating into herself, eventually becoming an otaku outcast. She resigned herself to being alone, but found solace in her hobbies.


Sumiye has personality that mirrors Hikari Tsutsui's. She is incredibly kind but socially awkward and finds dealing with people troublesome. She is also sensitive, prone to crying easily. Sumiye also has low self-esteem, considering herself unattractive and unworthy of being liked as a friend or romantically.
