We first learned about the OVA that was in the works for Eromanga sensei back in November 2017 with plans for it to see a 2018 debut. That’s now not quite happening as the OVA has now been set for a January 16th, 2019 debut in Japan. The OVA is coming out as two episodes with a nearly 50-minute running time total with stories focusing on Elf Yamada and Sagiri Izumi. It’s set for a 6,000 yen DVD release and a 7,000 yen Blu-ray release.
Check out our review of the first volume and our review of the second volume.
Ryohei Takeshita directed it while Tatsuya Takahashi handled supervision of the scripts for the series. Hiroyuki Oda served as the character designs and A-1 Pictures produced the animation for this Aniplex production.
The Japanese cast includes Yoshitsugu Matsuoka as Masamune Izumi, Akane Fujita as Sagiri Izumi, Minami Takahashi as Elf Yamada, Saori Ōnishi as Muramasa Senjyu, Ibuki Kido as Megumi Jinno, Yui Ishikawa as Tomoe Takasago. Nobunaga Shimazaki as Kunimitsu Shidou and Mikako Komatsu as Ayame Kagurazaka.
Plot concept: Masamune Izumi is a high school student who writes light novels. Sagiri Izumi is a shut-in who never leaves her room. A year ago, she became Masamune’s little sister. But one day, Masamune discovers a shocking twist- The artist “Eromanga Sensei,” who has been drawing illustrations for his novels, is none other than his little sister Sagiri! His cute little shut-in of a sister, who has been living under his roof, is using an obscene pen name and draws lewd illustrations?!
