A girl who lived a frail, sickly life and died young is reincarnated into another world, beginning her second life as Fiana—a girl blessed with an ultra-healthy constitution!! She grows up in “Lunamilia,” a village situated in an extremely dangerous territory where battle-hardened warriors and veterans gather. Raised in this harsh environment, Fiana grows so healthy and vigorous that by the time she’s older, she can knock out a dragon with a single punch! When she turns 13, she sets off for the magic academy in the royal capital. However, her excessively healthy physique means her punches and magical power are completely off the charts compared to normal standards…!?
