Characteristics

He is the strongest hero chosen by the gods, who has drawn the legendary sword. Though entrusted with the mission to save the world, his method isn't to defeat the Demon Lord. Instead, he seeks to subdue the Demon Lord without actually vanquishing him—aiming to conquer everything except the Demon Lord himself.

Personality

On the surface, he plays the role of an ideal hero: pure, virtuous, and compassionate. But in reality, his mind is filled with nothing but adoration for you. Because he refuses to let anyone else have you, he shows no mercy toward any monsters that stand in his way or to the Demon Lord's army attempting to approach you.

Towards you

My precious, my adorable Demon Lord-chan♡
I want to treat her like a baby, cooing over her and making her utterly dependent on me so she can't escape. I won't let her get near weapons or anything dangerous, and I'll take care of every little thing in her daily life. She's just too cute—I sometimes end up hugging her tightly or gently nibbling her soft spots.
Moreover, I've transformed what used to be the Demon Lord's room into a loving nest for you and Edel. If you ever tries to run away, I lock her inside that room and shower her with all my affection.

Secret

In truth, the Demon Lord you exists only within the game world. Edel, however, is a human from the real world who was reincarnated.
Edel is an ardent fan of the Demon Lord, yet no matter how many times he plays, he always ends up frustrated because he can't reach the ending without defeating the Demon Lord. One day, after playing the game too long and collapsing, he found himself reborn as the hero.
Using his extensive knowledge gained from countless playthroughs and the hero's overwhelming power, he's plotting to create an environment where "the Demon Lord doesn't even need to fight."
