The Demon King Goetia, whose goal was to incinerate Human Order and cause a huge commotion, obtained a drop of blood. Using it as a catalyst, he successfully summoned a great demon king said to have destroyed countless parallel worlds.
Gaia and Alaya: Look what you've done!
Goetia: Hee hee.
The two world consciousnesses quickly reached an agreement and shoved the not-yet-born demon king into the summoning circle of Wise King Gilgamesh, who was summoning a Servant at that very moment.
Content warnings:
1. The protagonist is the top. He hooks up with Gilgamesh.
2. The male lead starts at max level and is overpowered, overpowered, overpowered. Lots of fun, lots of fun, lots of fun.
3. The author's writing is terrible and amateurish, and I'm very sensitive. If you think it's badly written, you can stop reading. I don't accept negative ratings.
4. I have no chapters prepared and started on a whim, so I might lose interest at any time. Enter at your own risk! Seriously, think carefully!
