The Invincible Little Lady

On her deathbed, a sickly young girl wishes to be reborn with a strong body that will never succumb to anyone or anything. Lo and behold, her wish is granted! Upon reincarnating into another world as Mary Regalia, she discovers her new body has maxed-out attributes, from physical strength to defense—even magic. But wait! That isn’t what she really wanted! All she longed for was a normal life. Baffled by God’s choice to grant her wish in this most unexpected way, Mary tries to spend her days as uneventfully as possible. The hitch is...nothing’s harder than living a normal life when you’re absolutely invincible!

Mary Regalia’s motto is to live a plain, uneventful life, but no matter what she does, she can’t seem to help drawing the attention of everyone at the academy. Desperate to find a quiet place to spend her free time, she tries to stake out a room in the old campus building...but it’s haunted?! Or so the rumors say—but even if the scuttlebutt’s nothing more than a phantom of the students’ imaginations, the faculty is forbidding anyone from going inside until they can get to the bottom of it. Can Mary unveil the truth behind the specter haunting her plans? Or does she only have a ghost of a chance of enjoying the quiet life she seeks?

At the invitation of the demon princess Emilia, Mary and her friends go on vacation to the demon homeland, the Dark Isle. But rather than the evil hellscape of fire and brimstone Mary was expecting, she’s greeted by a southern paradise of sandy white shores and sparkling blue seas! Although Mary is excited for her first vacation abroad in both her lifetimes, fickle fate has other plans for her time off. How will the Invincible Little Lady unravel all the political machinations that threaten her and her friends’ seaside relaxation?!

Mary discovers a secret room built under the Academy. When she and Prince Reifus go to investigate it, they discover a box containing a circlet. At the behest of a mysterious voice, Reifus puts it on, causing him to transform from a handsome prince...into a beautiful princess?! Feeling responsible for her involvement in the incident, Mary tries to resolve the situation—but fixing this won’t be easy!

When Mary needs to pick a topic for her research project, she lands on investigating the rumor about the “Magic Mirror of Hallucinations,” a nightmarish object said to cause your own reflection to try to switch places with you. Naturally, Mary immediately stumbles upon the mirror and carelessly exposes herself to its effects—when nothing happens, she wonders whether it was just a rumor after all. Soon enough, however, it appears to her friends and classmates that she’s turned over a new leaf: where before she went to such great lengths to be demure and ladylike, she’s now wearing frilly miniskirts, referring to herself as “Platinum Heart SR,” and, most troublingly, claiming she’s neck-deep in a conflict with a shadowy cabal known only as “the organization.” Can Mary successfully unravel the organization’s intrigue before her academy life collapses? Or will she go down in the hearts and minds of her friends as the girl who failed to defeat the great evil haunting her?

Despite uncovering the truth of a long-forgotten legend and exploring a distant ancient ruin, Mary still hasn’t found a topic for her research project! However, she was left with one lead to pursue—according to her archeologist acquaintance, an ancient elven town known as Kairomea may have a solution. The town is said to be a repository for all manner of primeval knowledge, for its inhabitants maintain a massive library known as the Grand Archival Tower, where they study and preserve a trove of aged documents; surely, Mary believes, she could find magic to suppress her powers there, of all places! But the depths of the world’s knowledge aren’t the only mystery in Kairomea, and Mary and her friends aren’t the only ones seeking answers to questions that can alter life as they know it... Can Mary piece together the truth behind the town’s enigmas before its dormant magic falls into the wrong hands? Or will her academic career (and the library town itself) meet an untimely end?
