Ten years ago, mana descended upon Earth in the form of Gates that opened into other worlds. These Gates contained Magical Beasts of unfathomable strength and power that preyed upon humans and sought the destruction of everything around them.
But along with the Gates, humans gained the power of Gifts—super abilities that allowed them to fight back against the monsters and take back their world.
Now, the Superhumans with Gifts are tasked with defending the people and ensuring that the Gates, which open all over the world, do not bring about the end of them all.
...
Jason Marc was just your regular seventeen-year-old high school student whose father abandoned him ten years ago. He worked two part-time jobs while also helping his mom with her diner to aid with the finances, but he could have never guessed that his entire world would change on the eve of his eighteenth birthday.
Now, with more power than any one man should possess and an army at his beck and call, Jason works toward protecting those close to him while finding out the truth behind the emergence of the Gates—and preventing the end of the world.

Strongest Necromancer System

Strangers and other people weren't important enough for Jason to tell them anything about his abilities, and he didn't trust anyone enough to expose his system. But his family was important enough, and he trusted them enough to tell them about the Legion.

Jason sighed and spoke up calmly while standing.

"Okay, I need to show you something. You need to promise me you won't freak out, and you can't tell anyone what you're about to see here."

Gina's brow furrowed in surprise. She pulled her shirt down and sat up, placing her hands between her closed legs. She wondered what Jason could possibly be planning to tell her, and she couldn't even try to hide her curiosity when she spoke.

"What's going on? You sound like you're about to tell me something crazy, like you murdered someone or something… Wait. Y-You're not a murderer, are you? Because if you are, we need to figure out how to hide the body."
