This fall to the dark side is just depressing; an audible sigh of disappointment. I really hope this is just her being more okay with it and not continuing down this path of corruption. Her being the only straight "man" in the group feels like the main point of their character dynamic; you really can't take that away while still keeping balance of the force.
@Zookz I think her new found horniness is an effect of the body. Females in that world must have a higher hormonal production which is why they are so much hornier than males.
Meaning the protagonist will slowly succumb to her new biology and also the hentai protagonist will eventually become docile. Ohh and the isekai thot must be slowly turning less and less horny, otherwise she couldn't remain monogamous since she must be getting a lot of male attention from having such 10/10 body and 20/10 boobs.
How did I miss this chapter update? Also, nothing wrong with a sex drive, I am just personally not a fan of fucking any person, only someone I am in a loving relationship with
