During her journey to subjugate the Demon King, the hero Alicia wears a ring as a trophy.
Then, suddenly, a lewd mark is carved on her abdomen, and her body becomes so sensitive that even the friction of her clothes makes her cum.
She tried to take off the ring, but no matter what he did, she couldn't take it off.
"Maybe I should just cut off her fingers..."
"No, you can't... then I won't be able to wear my wedding ring with him."
Alicia had a fiancé whom she planned to marry once the demon king was defeated.
However, in such a state, it was no longer a matter of subjugating the Demon King.
When she asked the priest about the lewd crest at the church, she learned that the pattern carved on her abdomen was a curse called the ''climax crest''.
Alicia and the priest try to lift the curse by praying to God, but Alicia cums during the prayer and is unable to lift her curse.
Her only option left is to break the curse with holy water.
However, the holy water had been stolen by thieves just the other day.
Alicia sets out on a journey to exterminate the thieves in order to recover the stolen holy water and break the curse of her climax crest.
