Seeker_of_Chaos

[WSA 2025]
After dying while trying to save his childhood friend, Tyler finds himself in a world he knew all too well, but there are some very big problems. No, it wasn’t the fact that he was an extra; in this world, it didn’t matter if you reincarnated as the main character or an insignificant extra.

Steal the opportunities of the main characters and their companions? Nope, not possible.

Everyone in the world ends up dying except for the two main characters, and it's unavoidable. He literally doomed. 

So, what can he do?

There was only one narrow path open for him to become the only other strong character that could survive the calamity, the only one greatest nemesis of the main character, 
"The Demon King."

Extra's Path To Demon King

Axel appeared right above his head, and swung down the sword on the barrier using all of his physical strength, using his runic eyes and spotting the loopholes and weak points in all the magic artifacts and spells. But still the barrier did not break, so he simply continued to hack away at it, with his full physical might as his crystal mana empowered his mana circuit.

Cedric continued to speak one rune after another,

"Seal"

"Amplification."

"Chaos"

"Death"

"Reflect"
