I love how Yukino turns from "I hate you" to "I love you baka!" haha
Megu go from being the good girl to a whiny b*tch then back to a good girl
Like using the heart hybrid armor core, and the shape of the core turned into dildo sharing the sense of our MC penis, and inserting the dildo shaped core (Weird writing this one) into the females body through their vagina.
and she didn't had s*x with the guys that stole her as she had a amnesia and she came back to him when she got bacl her memories and loved him even more.
First of all... all girl is perverted in this novel at the beginning which caused MC to have a bad 1st impression of them., and MC yearn for a virgin girl because of this and not a slut, and he likes to be reverse raped, Which is a strange fetish, he yearn for a virgin girl but wants to be rape xD.
Next, this is a Femdom, he got raped by sluts, and he was having a complex about that, maybe because he wants a virgin to be his first... thats a harem, the MC is a herbivores but the Girls are good. His mind is hating it but his body is liking it, When reading this novel... pay attention to his actions and words instead of his monologue, he is a good guy in his body language, but a complete sh*t in his monologue xD, I enjoyed the Contrast.
At first the girl was a slut, but after they fell in love with Tanaka, they changed, and personally I like the fact that they remained loyal to him after they changed.
Those who said that the MC got NTRed are probably those who didnt finish the novel and dropped halfway.
Overall, I give 5 star because of the character development.
