Good and Evil are two sides of the same coin. Ones act of Kindness to someone might be an act of cruelty to another.

Ater found himself in a Novel where the protagonist destroys the world. A ray of light shines upon Ater as he gets an ability that lets him enter novel. He is able to come back with skills and items from the novels.

Ater and Ruber met and became friends and form the Black Heart and Red Fox Duo which enters novels to get skills and able to level up. The two need to get stronger in order to kill a regressor.

--------
What would happen to the Novel Worlds they left?
Will they be strong enough to kill a Regressor?
Will they be able to keep their friendship forever?

------
The MCs might seem playful and be able to outsmart opponents around the first 30 chapters.（maybe to much）
Well read until chapter 30 chapters when things starts to shift.

-----

（Warning please prepare yourself for laughing and cries.）
（there is involment of gore scenes）
（The first 30chapters are long as they have talk most of world view）
So give it a try before setting it aside
------

（I am not really an English Native so there might be a lot of errors in the first 15 chapters.）

I made this Novel out of my Love for [I Will Kill The Author] by [Night_Crawler619]. Most things might look similar. 
I even thought of naming it [We Will Kill The Protagonist]

Commercial Novel Invader

"Tsk, what the hell is this, why did that bastard Fritz destroy the World"

A 17 year old boy was sitting on the edge of single person bed at the edge of his small organized room. His dark blue eyes were staring at his cellphone.

" Whats this, living a happy life after killing everyone, those crazy girls in his herem can't even feel sad after their families were killed,"

He screached his dark blue hair and touched his earring with a short silver cross on his left ear, as he put his cellphone away and he went inside a blanket to go to sleep, but before he could go to sleep.

A piano sound came from his cell phone.

"Who is it calling at this time, its five minutes before midnight."

The boy took his cellphone but to his shock it was not a phone call but a message of a picture. When he openned the picture there was a frown on his face.

"Tsk, I know my name means black,"

Ater shock his head as he returned his phone back, those types of messages weren't something new to him. Ater just turned off the lights and went to sleep.

Ater didn't notice that he had left his cellphone on, reviewing a picture which was dull black all round. When the time on his cellphone reached 0000hrs, a black hole which come out from his phone which was in a black spiral form, started to cover his small room slowly.

When the whole room was covered black, the black spiral started coming to his phone and when the black hole was gone his cellphone had changed a little bit and it still showed the same time.

Blue holographic messages ware shown above Ater's head.

"Ater Heart what a strange guy, he is almost like me," Ater raised his back and sat on the bed and countinued, "But why can't I remember his face."

As Ater woke up, he first saw changes around his apartment room and the slight change in his cell phone.

"What the hell is this, my apartment seems a little bigger and whats with the black cover of my phone, it should be silver."
