SEX: prologue

This OVA, despite its title, focuses on youth rebellion rather than sexual content. It serves as a promotional video exclusive titled *SEX ~prologue~*, directed by Sayo Yamamoto and produced by studio MAPPA. The animation presents an original story set before the manga, depicting events when Kaho arrives and Yuki and Natsu first meet in Okinawa. To obtain the PV, buyers must purchase all four volumes of the Sex 30th Anniversary Edition manga, collect tickets from volumes 1-3, and submit them along with the postcard from volume 4. The Blu-ray Disc will be mailed to those who postmark their postcards by December 31, with delivery expected in March 2018. Pre-screenings were held from March 8 to 14, 2018, at the Liberty Gallery's Atsushi Kamijo solo exhibition.
