Lucifera, an E-rank Hunter, is betrayed by her guild members and left trapped in a dungeon.

By a miracle, she meets Ivan, an S-rank Hunter, and the two manage to escape together.

Fatefully, they fall in love.

“I’ll devote everything I have to make you the happiest wife in the world.”

Their honeymoon is as sweet as a dream, until Ivan disappears during a dungeon raid.

Determined to find her beloved husband, Lucifera enters the dungeon once more.

But what she discovers there is…

“Why are you running away, honey?”

“…”

“Are you scared of me?”

Now the master of the dungeon, Ivan begins to ensnare Lucifera with a darkness she’s never seen in him before.

“Lu— honey… Where did you think you were going with that body of yours?”

The man standing before her feels like a stranger. Is he truly the gentle husband she once knew, or a monster who’s lost his humanity?
