- Description from novelbuddy

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

PS. Cover not mine, I just found it on google.

The Strongest Magic meets the Mightiest Mecha.

I have stolen Golden Mechas from the deepest vaults of the most tightly guarded fortresses in the world.

I have personally destroyed more armies than the top three superpowers have in the span of the Absolute War - combined.

I burned down the terrorist megacity of Habon.

I was expelled from the Union of Heroes at a younger age than people are allowed in.

I have talked to Ancient Gods, loved women, and devoured mechas that would make superpowers cringe in fear.

I have faced demons head on in moonless nights others fear to speak of during the day.

I am deified in a thousand cultures, and labelled as the devil incarnate in the rest.

I am the Mecha Emperor.

You may have heard of me.

Excerpt from Chapter 1

This is where it all began.

A junkyard.

Oh no, this isn't your clean, mechas-only junkyard that was the 'starting point' of many mecha geniuses out there.

I have seen and heard my share of rags-to-riches stories, and many of them claimed that they had started from 'junkyards' and slowly grew to be where they were right now.

From Zero to Hero, they declared.

You can do it too, they said.

As long as you work hard, everything is possible, they claimed.

I call bullshit.

Life doesn't work like that.

After her death, a young woman is reborn in the world of Young Justice.But wait…why am I in jail?! Why am I Gwen Stacy, and what the hell is a Street level system?!___________________________________________Additional Tags - Harem, Yuri, Lesbian, Decent Harem, GxG, Young Justice, Love, Action, Romance, Multiverse, System, Smut, Lemons, R18, Cartoons, Anime, Live Action.
