During the demon-summoning ceremony, Aiwass finally recalled his past life's memories.This should be an online game that his family's company had released and operated for six years. Now, his foster father was the leader of the latest version's antagonist organization.He would expose his identity six years later, hesitate and then defect from the protagonist's side. Ultimately, because he decided to take a fatal strike meant for the player character, he was killed by his upright older brother in a transitional CG without even a chance to enter the main content.——But the problem was not too significant. Aiwass also knew many secret advancement routes exclusive to the player character, as well as the Nurturing Secret Sequel regulations of the various Paths. He believed he could reverse his unfortunate fate……So now there was only one issue left.“According to the original plot, shouldn't I have been rescued by the protagonist before this lousy ceremony even began?”Tied to the ceremonial altar as a sacrifice, Aiwass fell into contemplation.

Kevin Lannister was offered the chance to reincarnate by the goddess of Happiness for unknown reasons.

He finally got to live a life of luxury in his new life but something totally unexpected occurred.

His mother was kidnapped and his father fell into a coma.

Now, it’s been three years and a twenty year old Kevin wanted to visit his dad in the hospital but a cannibal suddenly appears before him, killing him before he could see his dad.

Was his life finally going to end without even finding out if his mother was still alive or not?

But before he could release his last breath, a system notification sounded in his mind.

[I am called Evil Stepson System. The goddess created and named me and my only purpose is to help you in seeking revenge, In other words, I’m here to make you the ultimate bad guy,]

[But I didn’t expect to see a weak human. Aside from your physique, your strength and agility are average and not fitting of someone called my host,]

“Parasite,” Kevin mutters. He has had enough of the system’s rudeness.

It might have evil in its name but that doesn’t mean the system should act so rude to him.

[Huh?] The system was shocked.

“What’s wrong? Cat got your tongue?” An evil grin appeared on his face. Finally, the system was flabbergasted this time around.

“You dwell in my head and you call me your host,”

“ This means you need me to survive and that makes you a parasite cause I ain’t your damn Uber,”

“You know what? I’m going to call you parasite as from now on,”

[You wouldn’t dare,]

“ I just did and I would again, a thousand times,”

[Why you little!!]

[Fine you win. What do I have to do to make you stop calling me that?]

“Hmm, If you help me accomplish my mission of ending every single one of those who captured my mother. Maybe then, I’ll acknowledge the fact that you aren’t a parasite,”

[Then I’ll definitely help you succeed,]

[As a matter of fact, your first mission is ready. Would you like to see it?]

“Yes,”

[First Mission: Pop your cherry,]

Kevin smirks and says. “You know what parasite, I think I’m beginning to like you,”

[Hehe...me too,]

“ You say what?”

[Nothing,]

Join Kevin as he tries to right the wrong of his previous world by making his family (especially mom) happy again.
