I'm The Lord of Heroes

They left me for dead. Rotting forever after being betrayed by those I trusted most, who am I?

The Sword Saint; The epitome of justice.

It was who I used to be. What I used to be.

[Do you want a second chance?]
[Y/N]

Now reincarnated once more, with this system given to me by that mysterious creature, I will make the world tremble upon hearing my name.

This is the ascent story of a miserable commoner whose life is about to change. Warn all kings, villains, gods and heroes: true calamity will at last arise.

And this is Kailan Rhaast -- me.
