Reincarnated as the Strongest Demon King, Yet Forced to Marry the Hero

Ugh! I actually became the Demon King!

What?! The hero has absolute power over the Demon King?

To stay alive, I can only become a good Demon King.

Why are you still here, Hero? I haven't done anything bad!

"What? You want me to be your wife? Aren't we both girls?"

"Hey, hey, hey! I haven't agreed yet. What do you think you're doing? You know this is illegal, right?"

"Waaah! Someone's forcing themselves on an innocent Demon King!"
