System Wars: Here Comes the Heroes! - Chapter 8: Gotta love Butterflies...

It begins on the mountain.

With the glint of a knife, a flash of steel in the hands of a sworn brother. A betrayal.

This is where it begins; he is given life by lightning,
baptized by thunder.

Those who had once betrayed him should all suffer in his cruel revenge.

Have you ever seen exposing holy vein?

“You are mine, and I am yours…”

The world cannot be saved by the victory of a single man. This book begins at the point where the climax should occur; the battle between a Demon Queen who is a little strange and a Hero who is a little curious.

However, not only do these two give up the battle, instead, they join hands to directly challenge the complicated social structure which dictates that humans and demons must forever be in conflict.

This is too reckless right? How can this be done? Undoubtedly, you are thinking that.

Come, please turn the page. You are about to read a story that has never been told before; the story of the Hero… and the Demon Queen.

In the world of dragons and snakes, the talented but congenitally sick martial arts master was reborn as the sole heir of the 19th-century Canadian manor owner. He thought he would make money by practicing boxing, but he took advantage of the industrial revolution to become a giant of the times. The opened template.

In the end, the original owner was a hopelessly sick and consumptive ghost! I am still a bastard having an affair with a gardener…

Wait, what’s up with the claw?

James Howlett looked at the bone claws protruding from between his fingers, and became more and more worried about his future.
