Kingdom of the Cursed

I've always enjoyed reading books related to the seven sins. I Had high expectations for this and was quite annoying that most demon sin effect on Emilia was linked to sex.
Lust: She has uncontrollable urge to have sex with Wrath
Greed: She is greedy to have sex with Wrath
Envy: She is envious of Wrath past lovers
Gluttony: She want a lot of touching and sex from Wrath
Wrath: An aphrodisiac.

It would have been cooler if Emilia had indulged in other Sinful acts apart from Sex.
