I'm Not the Hero! - if you like From Villainess to Healer this has some of the same "using game knowledge" feel as FVtH volume 1, but in a darker setting. What we have is worth reading and hopefully we'll get another volume someday.

I'm always bothered by the apostrophe in Knight's and's Magic's and I bounced off of volume 1, but I did enjoy the anime so I might try again on catch-up

Private Tutor has a cute cast, interesting magic and some good stories, but it's hard for me to overlook the abusive relationship of the main couple.
