Reborn to Master the Blade: FrHero-King to Extraordinary Squire ?, Vol. 5 (manga)

Reincarnated as a girl far in the future, former Hero-King Inglis has the chance to hone her fighting skills. The now fifteen-year-old Inglis, her cousin Rafinha, and their new friend Leone have just enrolled in the Chiral Knights’ Academy. Their school days are off to a roaring start as the girls face golems in a high-gravity arena, where Inglis stuns the school and shows them that she’s no normal squire! Next up? Flygear piloting lessons with a special guest: an underwater magicite beast! When the girls are recruited to offer protection for a trade deal, the principal agrees to sign off on their extracurricular activities...under one condition: the girls must brave the Labyrinth of Ordeals, where they’ll come face-to-face with demons from their pasts.
