Naoki Kawarazaki is Keita's senpai at school and a dedicated otaku. He pursues Yoko as he wants to use her as a model for a dōjinshi character, but unfortunately makes the mistake of complimenting her tail for its plumpness and comparing it to a tanuki's. Apparently, Inukami admire thin tails. He is a cosplay maniac, who enjoys seeing both men and women of any age dressed in "moe" female clothing. Kawarazaki is the first to name and organize the citizens of the darkness in the battle against Sekidōsai. He sometimes comes off as a pervert or psycho, (such as when he chases Tomohane around the entire city to use her as a model), but his intentions are always good, earning him respect from Keita and Yoko.
