“Big Brother Clyde, don’t be so dejected. You are now a well-known Suzerain, a hero of the entire continent, the Human Race’s Savior!”

“Lucifer, enough. I just want to return to my quiet life.” Clyde, an Evil God, had yearned for a quiet life, but by chance— or fate— he had met a young a mysterious Bloodkin Lolita named “Lucifer.” Under her guidance, Clyde embarked on his destiny, rising from the unknown as a nameless wanderer to become a Suzerain of a fief before taking the throne of the entire Ximengsi Continent.

Then let’s go together and find light together.

The moon is gone
And how silly cats were, always chasing after their tails
The childhood memories are priceless.”
