Arc was an ordinary young woman from Earth when she was summoned to an icy hell where she fought for her survival in the name of training to become a hero. Now, after defeating the Overlord itself and achieving the status of hero, she leaves with the goal of enjoying her freedom. She arrives at Arlas, a fantasy world with magic and monsters, a world with numbers, tiers, and classes, a world governed by the System that summoned her.

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.

The world is changing, and it needs a new Alpha. It needs me. I was doing well enough before the Apocalypse, but fast cars and penthouses mean nothing when the world changes into a wasteland filled with parasite-infested mutants. Now, the iron will that made me king of the boardroom is going to make me king of this new world. I am going to unlock my true power, I’m going to cultivate it, and I am going to dominate!

When a God of War barged into his apartment, Jake had no idea what to expect... but it wasn't being forced into a never-ending war against evil invaders, or that the battle would strangely resemble the MMORPG games he loved. Working hard and building himself up from almost nothing, Jake would need every bit of knowledge and preparation to master his new class of Summoner. Joined by a sly Demoness with an ancient past and a shy Valkyrie hoping to prove herself in battle, they'll find excitement and enjoyment as they level and grow in power.

Growing up, she was the girl down the street. Even then, I knew she was different. She was tough, rough, and had the strength to stop a speeding car with her bare hands. We were as thick as thieves, sharing every adventure. Then one day she revealed a secret. She wasn't from Earth. She was from a distant place called the Arcadia Multiverse. Her people lived under the rule of a god-like entity known as the System. That System had its gaze fixed on Earth. And it was only a matter of time before it came for us.
