It would be interesting, a protagonist who is corrupted by that force he tried to stop (like Anakin Skywalker lol), What do you think of a sequel where the antagonists defeat Kurt, the harem is totally corrupted? A few weeks later, "The Imperial Kingdom" sends a team of adventurers to investigate a possible demonic outbreak. We would see the now "harem of evil" try to corrupt the adventurers little by little, avoiding raising suspicions of the dangerous entities that inhabit the city.
Another interesting option would be Erona, something similar.
Kurt defeats the villains and recovers his harem but surprise, they are physically corrupted, Kurt decides to erase their memories in a (negligent) attempt to eliminate the "
" of having been controlled/manipulated by demons, some time passes, Kurt tries to make it happen His fantasy is to have a quiet life in the village with his harem, but he cannot satisfy them sexually. One morning the girls decide to collaborate even more at home by getting a job in the city. (You can imagine the job each of them chose), eventually they would fall into temptation, every touch, pinch, kiss and even smell would make little memories come back to their minds, they would find the castle library and try to revive the villains.
Now that I think about it, this could very well be an alternate ending lol
Some details about the girls' jobs in "alternate ending" 2:
Terena was going one morning to buy milk and eggs at the town stable. Seeing that no one responded she decided to sneak inside, thinking that the old farmer might be suffering from a cramp or something similar, then she saw him milking a cow. , while he watches how the skilled old man squeezed and pulled the animal's udders, making his heart, nipples and crotch beat very fast, for some reason he cannot look away, the deaf old man still does not notice his presence. , Terena can't understand why. Her body heats up when she sees that.
(If her memories return to her mind it is possible that one morning he will bring her "Terena's milk" for her breakfast without the rest of her knowing.
)
On the other hand, Rietta returns to the town church to continue helping, she decides to take care of the orphan children who live there, one afternoon while Rietta was hanging the clothes behind the church she observes that an unknown child comes running from the forest. . . . . , the boy falls at his feet exhausted from the effort while his stomach growls. He looked very unkempt, barefoot, with torn pants and mostly covered by a hooded cloak. Rietta helps him without hesitation, offering him water and food. The boy accepts a little. Fearful, upon regaining his strength, the boy explains that some very evil people came to his house and killed his parents and brothers. He was able to escape thanks to a stealth necklace (also used to hide the wearer's characteristics and abilities) given to him by his older brother. A worried Rietta decided to receive him in the church's olfactory, what she did not know was that this child was not human. He was a goblin, possibly a survivor of the protagonists' attack some time ago, it is possible that the little globin has sworn revenge, how will he carry it out?
(Of course, it can be 2 globlin children instead of one, it's up to you.)
About Arika, she now gives self-defense classes to the villagers due to the increase in monsters in the surroundings, every blow, brush, shock and push to her sensitive body makes her heart and crotch beat very loudly, some elders in the group realize . Taking this detail into account, generating one or another “tent”, it is only a matter of time before the “individual classes” begin.
(keep in mind that they may still have that boluptuous body that was generated by being in contact with the villains in the past, those bodies add more temptation for the Villagers and that is the idea, this time they will corrupt the people without realizing it Mind you, I think it's a little ironic that corrupt girls corrupt the town
lol)
