Naoki, Miki

直樹美紀

Miki is a second-year student at Megurigaoka High School. She is often seen with her best friend Kei, and the two take shelter in a mall for a while when the outbreak occurs. Eventually, Kei grows tired of waiting and leaves. Miki remains alone for some time until she hears the School Life Club girls on a supply run, prompting her to leave her shelter as well.
Initially, Miki dislikes how Kurumi and Yuuri simply accept Yuki's illusions, but she later understands their reasoning and warms up to Yuki. Unlike her passive time in the mall, Miki becomes very proactive after joining the School Life Club, frequently going on solo missions and fighting the infected like Kurumi.
