Reborn to Master the Blade: From Hero-King to Extraordinary Squire ♀

Having devoted his entire life to ruling and protecting his kingdom, a legendary Hero-King never gets the chance to just focus on getting good with a sword. When a goddess offers him one wish on his deathbed, he doesn't ask for paradise or power, but he asks to be reborn so he can finally train. The catch? He comes back as a girl named Inglis Eucus, born into a noble family in the far future. And to make things worse, she's Runeless, meaning she can't use the magical system that basically everyone in this world needs to become a knight. Instead of moping about it, Inglis decides to become a squire for her cousin Rafinha and use the position to obsessively pursue martial combat on her own terms. This 12-episode TV series from Studio Comet leans hard into the action side of isekai-adjacent fantasy. Where a lot of reincarnation shows hand the protagonist a broken magic system, Inglis is specifically locked out of magic and has to rely on raw physical skill and centuries of combat knowledge trapped in a kid's body. The gender-bending angle isn't played for cheap jokes, but it's more of a background detail while the real focus stays on fights and Inglis being quietly overpowered in a way that's fun to watch rather than obnoxious. If you liked the reincarnation setup of Mushoku Tensei or the calculated protagonist energy of The World's Finest Assassin, this one scratches a similar itch with a more straightforward action tone. Worth the time if you're into martial arts mastery stories with a fantasy coat of paint.
