Mecha: The Knight at the Top of the Empire!

He is the Empire's most powerful mecha knight, Langya.

He left the military without a word and returned alone to the imperial capital, Dragon City. No one knows why he came back.

From that day on, the Empire's most notorious intelligence agency gained a new member: an unorthodox King of Hell who plays by no rules, whether dealing with insiders or outsiders!

Young Lord: "Damn it, run! Don't let that guy see you!"

The Duke's second son: "Father, you have to stand up for me! He only ever hits people in the face!"

The Duke lowered his eyes. "You little wretch, you know that King of Hell only hits people in the face, and you still expect me to stand up for you? Do you think I don't care about my own face?"

The unruly princess: "You're avoiding me? Fine! All of you, go cause trouble outside the imperial city and draw him out for me!"

The palace maids and guards trembled. "Have mercy, Your Highness! We humble servants can't afford to provoke that King of Hell!"
