The Demon King Who Guards the Witch Prison

[Western Fantasy] [Laid-back] [Gourmet] [Invincible] [Easygoing] [Multiple heroines] [Character growth]

(Mainly everyday leisure and food, with a little fighting and education on the side~)

After transmigrating into the youngest Demon King on the continent of Sere, Iso only wanted to keep his identity hidden and enjoy a quiet life as the warden of Black Rose Witch Prison. He could also spend his days admiring the prison's most extraordinary inmates:

Witches, elves, succubi, mermaids, dragon girls, beast-eared girls...

“What? You want to know what daily life in the witch prison is like?”

“Of course, it's all about using a heart full of love and justice to have deep conversations with the girls from all those different races, and offering them counseling and educational training~”

That was what Iso would later say with a smile, entirely without remorse.

Then one day, a cataclysm struck, and the old world's order fell apart. The witches under his command simply draped an elegant robe over his shoulders:

“Demon God, it's cold. Put on another layer~”

Wait a minute...

I just wanted to lie flat. How did I become the strongest Demon God?
