Fantasy Assassin in a modern world - Chapter 9

She was a medical expert, talented and beautiful. She was reborn as his little wife. Her in-laws did not like her, her husband did not love her, and she was as timid as a mouse. She was weak and easy to bully.

Lucas is a homeless teenager who had everything taken away from him— his family, his home, his childhood. Even worse, he was born without any abilities in a world where humans with superpowers dominate.

All of that would change when a new dungeon appears before Lucas.

Thinking that it was a sign the gods have given him— that he should just give up and end himself, Lucas enters this dungeon without hesitation while expecting death.

However, inside the dungeon was not the end like Lucas had expected.

Instead, it was the beginning of his life of carnage.

Wielding the power of a «Hero», Lucas begins his journey of vengeance on the world that stole everything from him.

The story begins with the last day of Yggdrasil, a popular online game which is being quietly shut down. Our protagonist Momonga decides to stay in his beloved game until the last moment, so waits for the forced logout. Unexpectedly, the server does not shut down and Momonga is stuck in a skeleton avatar in another world. “The powerful Overlord” needs now to discover the new world and face the continuous challenges that arise.

Nagasawa crossed to Naruto Universe and was bound to Konohagakure.

If Konoha is severely damaged and destroyed, Nagasawa’s lifespan will be reduced.

He panicked at the thought of the upcoming Nine-Tailed Demon Fox’s attack , and the thought of Konoha getting destroyed left him in despair.

Fortunately, while bound to Konoha, he can obtain templates of powerful characters.

At the beginning, He got the Whitebeard template! Since it’s the Whitebeard from the Summit War of Marineford, he can use Tremor-Tremor Fruit’s ability and Haki.

Facing the Tailed Beast Ball, which terrorized Konoha Shinobi, Nagasawa leaped and shattered the Tailed Beast Ball with one punch!
