One day, I reincarnated as Asta Crawford, a game character.

Asta is the infamous villainous noble from the game [Astral Frontier], a despicable pig of a man who makes the commoner protagonist his sworn enemy and tries to steal the heroines away.

Furthermore, he never becomes an ally in any route, and in the end, he is brutally murdered by the protagonist, the Demon Lord, or others.

Yes, my future was already utterly hopeless.

However... this Asta, one of only a handful of characters in [Astral Frontier], possessed what internal analysis showed to be an incredibly overpowered ability called [Elemental Magic].

"The Asta in the main story slacked off his training... What would happen if I seriously trained?"

I began my efforts to avert the flags of ruin.

As a result... I became capable of one-shotting enemy characters and ferocious monsters, and eventually, the heroines from the main story started gathering around me.

"Huh? This is going to break the scenario, isn't it... Well, whatever!"

――This is the story of a villainous noble who, using his overpowered lightning magic, came to be known as the [Thunder Emperor].
