Hiromi Takashima’s Kase-san and Apron (Apron to Kase-san) was released on 25 July 2017.

Kase-san is a series which was first serialized in the Pure Yuri Anthropology Hirari and is currently being serialized in the Web Magazine Wings (both from Shinshokan). Until today, three volumes have been released of the manga and in early May an animation clip called Kimi no Hikari, directed by Takuya Sato, was uploaded on YouTube.

Kase-san and Apron will be released in two versions, one containing a Blu-ray and booklet with the anime clip. In this volume, the two girls will experience their last culture festival in high school, while they harbor the dream that they might be able to live together if they make it into a university in Tokyo.
