(January 28, 2026) — Seven Seas Entertainment is excited to announce, through its Ghost Ship imprint aimed at older male readers, the license acquisition of the Mature-rated manga series I Don't Know, Yoshida-san by Osamu Takahashi. A sexy manga about two college students and the intimate relationship they share in secret. From the author of Lust Geass and Neon Genesis Evangelion: The Shinji Ikari Raising Project!

Kutsumo is a perfectly average university student with no redeeming qualities whatsoever. One day, while heading home after a perfectly normal day of lectures, he spots beautiful Yoshida. Over a loud fuss the other boys make, she quietly beckons to him. Once the two are alone, Yoshida's aloof demeanor changes into one of passion. In truth, the two are in a secret relationship. But with her cold personality, he's never sure just where he stands. Can Kutsumo turn Yoshida's private desire into a blaze that cannot be contained?

I Don't Know, Yoshida-san Vol. 1 will be printed for the first time in the English language in November 2026 for $14.99 USA / $18.99 CAN, with the series available in single volume editions as part of Seven Seas' Ghost Ship imprint. Ebook editions will also be available on digital platforms.
