I'm a villain within the hero's party - Chapter 30: Kael Caskore, 7th Rank

Shaman, a normal teenage girl falls asleep on the eve of her 18th birthday like any other night. She awakens to find herself in an unknown place in an unfamiliar body with an unhelpful voice in her head.

On top of that, she has gained fox ears and a tail, she also seems to have memories of this new world and the body she finds herself in. Unfortunately not all of the memories are clear and she must rely on this rpg like system in her head to both unlock these memories and guide her on a path home.

As she explores the world she finds that it is somehow both modern and old, with magic permeating every day life. Architecture reminiscent of the 1700s clashes with modern day conveniences enabled through magic.

Will Shaman be able to make use of her knowledge of video games and novels to take advantage of her rpg system in this new world? Or will she be dragged down and entangled by the darkness of the world around her as she searches for the truth behind her circumstances? Many eyes are upon her as she takes center stage in this new world.

A modern-day antihero, who was infamous for his devious acts, dies in an explosion meant to take down a powerful criminal syndicate. Waking up in a world of sword and sorcery, he finds himself possessing a fragile, powerless body with a strange “System” that seems broken. Initially thinking he's doomed, he learns that by pretending to be weak, he can manipulate others into revealing their secrets, granting him abilities they possess. As he rises in power, he discovers that the System was intentionally sabotaged—by none other than his own future self.

As the mad researcher in a tattered white coat activated the self-destruction device, Qin Luo knew that this time, there was no escape.

He was well aware of the destructive power of the self-destruction device.
Even if he is genetically inborn with an independent space, it is impossible to use the power of his space to resolve against such a terrible explosion.

His only end would be a torn space and the crushed bones.

On an unrecognizable earth rampant with zombies and mutant creatures, this end is good.

Death is far better than living…

With a skull splitting headache he opened his eyes to find himself reborn in the year before the apocalypse happened.

Is this a joke!!!
Is this a chance for him to be prepared to combat the apocalypse?
Is God not satisfied with all the bitterness he had went through and would enjoy watching him suffer once more?
