A trailer for this month's OVA adaptation Yuri Seijin Naoko-san, releasing in Japan on February 15. The anime is created by studio ufotable, based on a surreal gag comedy manga authored by kashmir. The story follows a timid girl named Misuzu, whose older sister Naoko is returning from studying aboard. However, when she hurries home to meet her sister, Misuzu instead encounters Naoko-san, the strange alien from Yuri-sei (Yuri Planet) who is obsessed with yuri (lesbianism) and little girls, and is plotting to conquer the Earth by "yuri-nization". The first OVA short (of only 6 minutes) was bundled with the manga's limited edition Volume 3, at the end of 2010, and now this proper OVA episode is about to be released on Blu-ray and DVD.
