After waiting a lifetime and then some, Mary finally gets to try something she’s always wanted to do—go to school! She enters the storied Altolia Academy with her friends, where she lands a spot in the Solos class, whose students study the ways of combat. There, she meets a shy girl named Safina, and they become fast friends. However, it turns out that this could be Safina’s last year at the academy... She’s betrothed to an absolute cretin, and if he beats her in the upcoming martial arts tournament, she’ll have to drop out! Can Mary save her friend from this predicament? And can she do it without accidentally winning the whole thing and standing out even more? Join the invincible little lady and her friends on the next chapter of her adventure as the academy arc begins!

Mary’s not-so-peaceful school life enters its second year! She and her friends try to secure a hangout spot in an unused building, but they uncover a heinous plot to turn the academy into a haven for the undead! Later, a splash of mandrake sap imbues Mary with a constant mesmerizing charm that captivates anyone who sees her. It sounds swell—except it means being stalked by swarms of drooling fans! Also, one of the slime research society’s experiments gets loose, growing so enormous as to threaten the safety of the school itself! Can Mary cleanse the unused building of its undying spooky spirits, herself of the mandrake’s unrelenting aroma, and the campus of its unceasing ooze growth without drawing too much attention? Or will the legend of the White Princess prove as immortal as the forces throwing wrenches in her plans?

Mary’s now a third-year at school, which means she’ll finally get to settle down and relax, right? Wrong! She comes up with the bright idea of turning the school’s martial arts tournament into an academy festival, then His Highness Prince Reifus ropes her into running security for the event. That wouldn’t be so bad, except that Her Majesty the Queen decides to visit the festival—which leads to Her Majesty’s mischievous childhood friend, Princess Emilia from the demon kingdom, showing up to fly around and cause all sorts of mischief! And if that weren’t enough, mysterious intruders are spotted among the crowds... How will Mary get out of this little pickle? Follow the invincible little lady as she dons her silver armor and fights for her friends, but just remember—she’s definitely not the Argent Knight!

The demon princess Emilia invites Mary and her friends to the island kingdom of Relirex for a much-needed summer vacation! However, on the way, their ship runs into some trouble with pirates...ghostly ones, at that! Once they finish braving the troubled waters and reach their destination, Relirex turns out to be a beautiful island getaway. However, it’s not all rest and relaxation: the port town’s mayor, Dabzal, has political aspirations that may have more to do with the invincible little lady and her friends than they anticipated... On top of that, Mary has caught the attention of a talking leopard—yet, according to everyone she asks, anyone who hears leopards talk is either delusional or a powerful holy woman! How will Mary and her friends react to Dabzal’s movements? And can she convince them that she’s not a walking saint, she’s just really good with cats? Find out in this first installment of Mary’s adventures in the demon kingdom!

Despite her best efforts to become a footnote, Mary has discovered Mayor Dabzal’s secret base of operations, blowing the conspiracy that threatened her and her friends wide open! While there, she confronts the famous magus smith Girtz, who is integral to the mayor’s dastardly plot...only to learn there’s a cat in the pan! Or one in the storage room, at least. Meanwhile, several of Mary’s friends are attending Dabzal’s dinner party, patiently keeping watch over him to see which way the cat jumps—and once he ducks into a secret passage, they know it’s time to pounce. With the ball of yarn he worked so hard to wind coming loose at both ends, can Dabzal claw out a victory? Or will Mary and her friends make him face the mewsic?

When Mary and her friends try to take stock of all the academy’s derelict unapproved research projects, they stumble upon an underground room housing a small box. Surely, whoever went to the trouble of putting this box so far out of the way must’ve thought no one should ever open it under any circumstances...a fact that becomes all too apparent after the prince dons the magic tiara inside and finds it impossible to remove! Far from merely being a very persistent accessory, the prince’s new headgear is an ensemble piece, lengthening his hair and granting him a feminine physique—as best as anyone besides Mary and co. can tell, he’s now a beautiful young girl. Fearing for her behind if word should get out about what befell the prince under her watch, Mary gets on the case to find a way to peel the tiara off his noggin. Will the invincible little lady manage to lift the prince’s curse before it’s too late? And all the while, the world’s oldest, strongest vampire begins to make her move...

Now that the vampire Victorica Bloodrain has given Mary a bead on elven magus smith Shelly’s whereabouts, it’s looking like her journey to take off Lady Rain’s tiara is reaching its end. With her friends and Victorica in tow, Mary heads for the elf village to meet Shelly and get her help undoing the fairy’s mischief...but are things ever so easy? It turns out Victorica is, unbeknownst to her, a longstanding enemy of the village! Meanwhile, once the gang meets Shelly, she reveals the tiara won’t be coming off for at least another decade—that is, unless Reifus is willing to risk losing his soul negotiating with the fairies dwelling in his tiara! Lastly, as her allies grapple with these life-altering ordeals, one thing weighs on Mary’s mind before all others: is she managing to act like a normal village girl? With their paths before them, can Reifus, Mary, and Victorica surmount the crucible of the elf village? Or have the invincible little lady and her friends finally met their match?

For her graduation research paper, Mary decides to try investigating the Magic Mirror of Hallucinations, which people say makes a killer copy of yourself when you see your reflection. When Mary and Magiluka find it to confirm the truth, it’s a dud, so they figure the rumors must be nothing but smoke and mirrors...but soon enough, the girls start feeling like they’ve stepped through the looking glass! The next time Magiluka meets Mary, she claims to be the target of a villainous secret society known as the Org—and to stop them, she’s unleashed the magical girl power within herself, transforming into Platinum Heart SR! Meanwhile, the next time Mary meets Magiluka, she’s totally abandoned her classy bearing and wants nothing more than to hug and squeeze Mary at all costs! Will the girls be able to handle each other’s stunning reversals? Or will their treacherous images get the best of them?

With the Org cornered, Magiluka braces herself for a grueling confrontation with their massive chimera...only for mirror Mary to instantly take it out with her Galactica Eccentric Kick?! Seeing her friend’s (exact copy’s) flying kick send a two-story-tall monster tumbling across a courtyard suddenly puts many of Magiluka’s past experiences in a new light—just who is Lady Mary, really, and why has she kept her actual power secret for so long? Can the two of them truly be friends now that Magiluka knows the part of her she keeps hidden? Magiluka will surely get answers if they can just talk it out...but once she’s forced to face the Org’s ultimate weapon by herself, will she survive to have the chance?

After Mary put Magiluka through a hall of mirrors with the whole clone situation, she feels obligated to treat Magiluka to a relaxing hot spring getaway to aid her recovery. Of course, when she takes Magiluka, Safina, and Victorica to one that’s apparently near Castle Bloodrain, she inevitably drags the girls into yet another adventure! As it turns out, the hot spring they’d sought is home to a dungeon-themed spa resort, complete with lethal traps and hidden switches to really get you in the rest-and-run-from-peril mood. The girls, along with a profusely muscled archaeologist they meet at the entrance, venture further inside in an attempt to locate and enjoy the baths...but the traps end up eliminating their way out, and then their group gets split up to boot! Will the gang manage to reunite and spring themselves from the labyrinthine spa resort? Or has Mary’s ability to keep her friends safe at last run out of steam?
