Power Day occurs every year on September 15th. Across the world, formerly regular people awaken with superhuman abilities—and labels to go with them. They become the next generation of Heroes...and Villains. September 15th is also Emily Wright’s first day on campus. While everyone else is out celebrating the start of their college career, Emily’s hiding in her dorm room. She wonders if it’s possible to earn a degree while completely avoiding eye contact with anyone. All she wants is to learn a little. Instead, she’s granted a superpower and categorized as villainous.

Elaine is ripped from this world to Pallos, a land of unlimited possibilities made real by a grand system governing classes, skills, and magic. Join Elaine as she travels around Pallos, discovering all the wonders and mysteries of the world, trying to find a place where she belongs, hunting those elusive mangos, all while the ominous Dragoneye Moons watch her every move.

Catherine "Cat" Leblanc is an orphan that is about as far from super-rich as one can be. When the Incursion alarms start blaring and the sky starts raining hungry xenos, it's just another blemish on an already piss-poor afternoon.

The world called out for a hero to purge it of a great evil. It received Broccoli Bunch: explorer, expert cleaner, occasional ghost-buster, and full-time Cinnamon Bun.

Nature is dying. Perhaps before the world is turned into an industrious machine, nature itself can play one final trump card to save itself. Summoned to a new world, a mushroom-loving mycologist needs to grow up and grow stronger in order to accomplish the goal that brought them to this new place: to save nature from the system that the sentient races have created. Stats, levels, classes, and skills are all well and good, but when you're a Child of Poverty in the slums of City Nineteen, there's little you can do to change the world. Not unless you're willing to think outside the box!

Magic is fading, and humanity is at the brink of extinction. Sybil lived and breathed the life of a miner, delving deep into monster-infested caverns and perilous shafts, risking her life to unearth Relics of an ancient past for food and shelter. That is until one day, she discovers a Relic that would change her fate from a simple miner to an Ascended—a Relic that connected her to the magic that was once lost.

The usual result of a human taking a runaway semitruck head-on is a very sudden, very fast track to the pearly gates. But for one newly noncorporeal man, there's another option: become a dungeon. Feeling sorry for the desperate angel assigned to him, the man relents. Heck, if it doesn't work out, he can always chat with Saint Peter about it later. Next thing you know, he's a dungeon. Admittedly, a small run-down, somewhat unimpressive dungeon (more of a house, actually), but you gotta start somewhere, right?

She wanted to be a Necromancer, but awakened as a Saint! Somehow her summoned heroes are all undead? How will the church react when their Saintess summons a skeleton in place of a mighty hero? Sofia isn’t too keen on finding out. In this world, Gods choose [Saints], and [Saints] summon [Heroes] from other worlds; everyone knows that. But Sofia had a thing for bones ever since she was a child; there’s only one [Class] she wants: [Necromancer]! When, by the whims of fate, she gets both classes at the same time, the system breaks.

Davi has done this all before. She’s tried to be the hero and take down the all-powerful Dark Lord. A hundred times she’s rallied humanity and made the final charge. But the time loop always gets her in the end. Sometimes she’s killed quickly. Sometimes it takes a while. But she’s been defeated every time. This time? She’s done being the hero and done being stuck in this endless time loop. If the Dark Lord always wins, then maybe that’s who she needs to be. It’s Davi’s turn to play on the winning side.

In the distant past, a time of magic and swordplay, there lived Harold, the mightiest lich of all, a master of arcane sciences, and a challenger of gods. After reaching the pinnacle of his power and finding it surprisingly bland, Harold waged a cataclysmic war against the gods, aiming to shatter the very system that confined him.

When Alice Verianna went to sleep, she was just another teen from the Denver suburbs. She definitely didn't expect to be transported to a magical alternate dimension, inhabited by monsters and presided over by a mysterious System. Here, people resemble RPG characters and everyone has access to their own status screens. Grappling with the mechanics of the elusive System isn't the only challenge Alice faces. It seems an underground organization known as the Society of Starry Eyes has taken a particular interest in other dimensions.

Anya Nowicki, along with thousands of people around the globe, has found herself a host for alien technology known as the Archive. The Archive allows its hosts to alter their minds and bodies in an instant through holographic menu systems. With the touch of a button, anyone can become super strong, gain magical abilities, purchase a giant robot, or become a master in an almost infinite number of skills ranging from advanced combat techniques to fidget-spinning.

Awakening in a world of myth and magic known as Vularia, Amara has been reborn as a Trickster Cleric, an avatar of the goddess Melischar. She has been tasked with rallying the Forces of Order against the legions of the Chaos Gods, who want to bring about an apocalypse. Amara is the first avatar to appear in a millennium, and Melischar is a deity of mischief, mistrusted by the other gods. The servants of the god Sirveig believe Amara to be a false prophet sent to sow discord across the land, an enemy they cannot allow to live.

Alexandra Rousseau, an engineer from the European Federation Star Navy with a past darker than the void between the stars, is unexpectedly launched into hyperspace when an FTL jump goes horribly wrong. She wakes in a world of magic and monsters, encountering a mysterious Order with plans millennia in the making. When the Order makes a catastrophic mistake, transforming Alexandra into a dungeon core, they inadvertently give her the power to bring back technology long since thought lost in this world.

Ten years ago, Amelia woke up alone and lost in a broken world where she had to fight for her survival. Now, after reaching the pinnacle of power, defeating the Void itself, and escaping the abyss, she has finally found her way back into the real world. But instead of returning to Earth, she arrives in the land of Vacuos. A fantasy world with magic, monsters, Classes, and Levels. A world that is governed by a System like it were a video game.
