It’s really an egg! Damn it, what kind of monster have I become? Did I fall into Hell instead of making it to Heaven??
Join Roy as he ventures through various worlds with the Custom Made Demon King System—a system that allows Roy to draw anything he can imagine and create it through exchanging souls!

A pair of young girls that appear to be the same age act like a mother and a daughter. They are on a journey for one reason: to obtain a medicine that will stave off the daughter’s disease. Killing demons, deceiving people, and giving her everything in hope that there’s a way of rescuing her daughter. This is the story of their fragile hope and overwhelming despair.

This legend tells the tale of the protagonist, Kuroki summoned to protect the demon king from the hero.

Kuroki, unbeknownst to him, suddenly came to another world. He was summoned by the demon king, Modes. The territory which the demon king overrules was in the midst of being destroyed because of the hero. He had no choice but to bow before Kuroki.

“Please save us, Savior Dono!”

Kuroki nodded, deciding to save the demon king due to an unexpected turn of event.

Jian Chen, the publicly recognized number one expert of the Jianghu. His skill with the sword went beyond perfection and was undefeatable in battle, After a battle with the exceptional expert Dugu Qiubai who had gone missing over a hundred years ago, Jian Chen succumbed to his injuries and died.

After death, Jian Chen’s spirit was transmigrated into a completely foreign world. Following an extremely fast growth, his enemies piled up one after another before becoming gravely injured once more.

On the gates of death, his spirit had mutated, and from that moment henceforth, he would tread on a completely different path of the art of the sword to become the sword god of his generation.
