The ComicFesta Anime brand announced that its newest television anime is based on the JimiHen—!! ~Jimiko o Kaechaū Jun Isei Kōyū~ (Pure Heterosexual Intercourse That Transforms a Plain Girl) manga by Iburō. The anime will premiere on Tokyo MX on January 3.
The story follows the relationship between two co-workers, office worker Rena Yukuhashi and businessman Ryōhei Hachiya. Yukuhashi seems like the plainest woman at her company, but she transforms into a stunning beauty when she dresses up outside the office. Flustered upon seeing Yukuhashi transformed, Hachiya inadvertently utters what sounds like an invitation to get to know each other better — without realizing they are standing in front of a love hotel.
The cast includes:
Kazane as Yukuhashi Rena
Kawamura Mahito as Hachiya Ryōhei
Fujisaki Usa as Sekiguchi Rie, a co-worker
Nanashino Hibiki as Buchō (Manager), Boss
Ishikura Rei is directing the anime at Studio Hōkiboshi and co-writing the scripts with Kurosaki Eeyo. Kuroda Kazuya designing the characters and is also serving with Kakuto Gai as chief animation directors. Takahiro Enomoto is directing the sound at Studio Mausu.
The “premium edition” of the anime with adult scenes will stream on the ComicFesta Anime website on January 3 at 24:00 (effectively, January 4 at midnight). The “on-air edition” of the anime will premiere on the Tokyo MX channel on January 3 at 25:00 (January 4 at 1:00 a.m.) A special about the new program will air on December 27 at 25:00 (December 28 at 1:00 a.m.) on Tokyo MX.
