Maou-sama no Machizukuri! ~Saikyou no Danjon wa Kindai Toshi~ - Volume 8 Chapter 1

I was a 28-year-old researcher in Japan, and before I knew it, I have been reincarnated in a fantasy world.

Furthermore, I had a half-spirit father and a spirit mother.

An aunt who is deeply attached to father, cousins who are problem children. Girls who cause awkward situations as in an otome.

Furthermore, in order to gain the affection of a love interest, a cousin even had a word battle with a king!

I am very busy helping humans as well as spirits!

And when I find people who are targeting my father,

「I’ll crush you.」

The cheat protagonist deters those who aim at her family. This is such a story.

Majiatisi Lei En, the sole Descendant of the Heroes is the nightmare of his entire town.

The apprentice of a proud Warlock, Lei En works hard to learn his trade unknowingly causing mayhem for those around him.

So when he stood on the tower of the Supreme Wizard, shouting with a heroic flair:

”I want to be the greatest of the alchemist of the Shenji Continent!”

A resounding roar of, “Boos” from the townspeople was the only response he got.

A person's perspective plays a vital role in developing one's personality. What happens when you realize the world you live in is the same as a Novel.

Zero Elea gets a Skill called Parallel Memory which allowed him to get the memory of his alternative self of a different universe.

He realizes that the world he lives in is similar to the novel he used to read in his alternative world. The world will face catastrophe in the future but there is no need to worry as there is a main character working hard to save the world.

And what about me? I am but a mob character.
