Look, we all know what an isekai story is, and I'm sure you can guess from the tags exactly who's involved, but just to be sure: the blonde noodle dies at the end of Volume 3 of RWBY instead of Pyrrha, and gets isekai'd to Camelot. A spin-off of All The Difference In The Worlds to mark the one-year anniversary of it, with exactly the quality you'd expect (read: none).

King Roland Holfort is dead. The Holfort Kingdom is embroiled in a chaotic civil war between the Crown Prince's loyalists and Duke Redgrave's rebels, who besiege the capital. Meanwhile, Leon and Marie have snuck into the royal palace ahead of the vanguard, in order to confront the Saintess behind everything. Naturally, nothing goes as planned. Post-Marie SS with an obvious twist.

"The right man in the wrong places can make all the difference in the worlds". Unfortunately for Jaune Arc, he finds himself in the wrong place when he pushes Pyrrha into that rocket locker and takes her place at the top of Beacon's tower during the Fall. Even worse, that isn't the only wrong place that awaits him! RWBY/Skyrim/Fallout/DOOM/FATE X-Over.
