Are You Referring to a Regular Female Knight, or a T*ash-Tier Female Knight?

One of the Four Heavenly Kings of the Demon King’s army, the Dark Knight.

His fearsome reputation precedes him, and he is considered humanity’s strongest and most evil enemy that must be defeated.

“I want to quit…”

However, this Dark Knight, who is feared not only by humans but also by demons, is actually a cowardly, good-for-nothing who simply wants to leave the Demon King’s army.

One day, this Dark Knight fights against a female knight from the human army and emerges victorious.

Expecting noble and virtuous words from the beautiful female knight as she is cornered, he waits for her to speak. Finally, she opens her mouth:

“No, don’t kill me! I’ll spill all the information about my comrades, just please don’t kill me!”

“Uh… huh?”

With this unexpected female knight now by his side, the Dark Knight is summoned by one of the Demon King’s daughters, who is embroiled in a fierce battle for the throne of succession.

Since she has a reputation for being dim-witted, he decides to meet her casually… only to hear her say:

“Please make me the Demon King.”

[(Caught up in a power struggle!?)]

This is the story of a reluctant Dark Knight who, through misunderstandings and self-inflicted misfortune, rises to power despite not wanting any part of it.
