Dxd: A demon Among Devils - Chapter 29: []:

Molitia Clemence was born sickly.

She forgot to cover herself with a blanket and caught a cold. She woke up next to her husband after 10 days just because of a slight cold.

Molitia barely survived between the thin threads of life and death. When she opened her eyes, she noticed that her husband was somehow acting differently than usual…?!

***

“Have you eaten?” (Husband)

“Yes.” (Molitia)

“This is the belly of a person who ate?” (Husband)

He frowned as he stroked her flat lower abdomen. He held her wrist carefully, as if it would break. His voice rose.

“Why is your wrist so thin? Are you even human?” (Husband)

“That’s…” (Molitia)

“Butler!” (Husband)

The butler rushed to his angry voice, fidgeting with his wrists.

“Get me food for my wife to eat. Something that will help her stay healthy. Anything is fine.” (Husband)

Molitia’s mouth opened at her husband’s words, but no sound came out. ‘I just had a meal?’

A normal office worker, Toru Minasuki, was swallowed up by a dimensional fissure and reincarnated into a different world. Upon reincarnation, Toru was given a [skill board] by God. Make the most of it to acquire all the necessary skills! Even though he is an “inferior person,” he’ll make his way to the top!

“A qualified gunner should have enough firepower coverage.”

“So my battery has a diameter of three thousand meters, which is very reasonable.”

After a grand fireworks, Chen Jiang looked at the shocked eyes of the passers-by around him and said seriously.

When all races were thrown into a world and started to fight, a world with the theme of survival began.

- Description from novelbuddy

Cliche. Another monster progression story. That was probably what you thought when you read the title of my story. And, I can't lie, for the most part, it probably is.But, what else am I supposed to do when I've been thrusted into a world that could kill me in an instant? There's nothing to do but to progress, to devour and evolve. You would do the same too.Such is the basis of a monster.Such is the right of any living being.So that's what I did. I ate, I killed and I hoarded anything I could get my big limbs on. Friendship, allies and love? There used to be a little god calling himself “Heaven's Equal” who spouted of such things, before I ate him. The world went pretty quiet after that.Follow my story. Read for yourself how I evolved from a little monster in a lake I thought was the ocean, all the way into the Titan Of Destruction.What To Expect:- A relatively quick progression story- Ruthless, I mean - Fang Yuag levels - of ruthless protagonist.- A system? that grows stronger along with the protagonist- Big Monsters Duking It Out, with minimal humans/beastmen/elves, etc. . .focus. Basically, monsterverse without annoying ass humans ruining the show.- Did I mention that the protagonist was pretty evil?
