Premieres October 2025. The new PV is here. Check out the ANN article for additional information. Synopsis from AniList:
When Akira’s class is magically summoned to another world, he and his classmates are awarded fantastical powers–but while one of them is lucky enough to become a true Hero, Akira becomes a mere Assassin. However, against all odds, the Assassin just might be the most powerful role of all! Harboring doubts about the intentions of the king, Akira uses his newfound strength as a master of the shadows to uncover the secrets and conspiracies of the crown.
First, I was like, “wow, that title sounds stupid.”
Then I was like, “Hold up, the PV actually looks pretty cool with nice style.”
Finally I was, “But now the summary makes it sound stupid again…”
What a rollercoaster.
I’m pretty sure I read this one (not 100% because there are like 3 that have the exact same premise). And if its the one I read its pretty good for being a standard isikai.
Have not read any of this novel / manga but it probably won the production Gacha by having Sunrise produce it.
