TL:dr of @Sukijoe comment. bro can possess multiple people at a time, and can see the memories of those people.

i wish i had mental capacity to overanalyze hentai

And then the slime gets to have its own main body that boosts its hijacking capability even more and can "level up" by absorbing a victim's intelligence and such, all the while having its harem ready to serve him day and night (only using them at night for sexual use for now). To be continued in volume 2.

The info below only applies to the victims who have some degree of compatibility with the slime. As for Azuza, it is very unfortunate of her, but such is the decision that the author came to. She is no more of herself because the slime has found out that after hijacking so many people he finds that there are compatibility aspects that came to be. Certain people can resist the slime's intrusion to some extent, but they are not able to force eject the slime out of their body or be aware of the slime's existence should it hide itself. The slime goes on to gain further knowledge of this finding with the help of Natsuki's intelligent brain and finds out that Azuza has a 100% compatibility rate with the slime which means it can infect a potential host without the requirement of leaving out of its current host and had to leave a fragment of itself. Azuza then gets absorbed completely by the slime because of the rate, soul, and all.

When someone didn't read the full story of some moral-breaking degree doujinshi and proceeded to ensure their sanity by escaping reality; this is the case with @ajfree. True, the man transforms into a parasitic slime entity and could hijack someone's body by entering its victim bla bla bla. But their victim only awakens if the slime leaves their recent host and does not leave a fragment of it to have total control of their physical host's body. The parasited victims can not break free of their own because the slime does not age and more so if said victims have had their self-entity absorbed by the main slime body or being controlled by one of its fragments; they can not break free of their own either way because they do not have some control or means to regain their rightful rights. That is the core of this type of doujinshi.

I surprising like it

Damn parasites wasting a damn yuri smh

Crazy stuff going on here

thanks dude @ajfree

In this story, a man undergoes a transformation into a parasitic slime entity. He discovers the ability to temporarily take control of and program some of his female victims. However, these victims can break free from his control over time (only time will tell). As he gains knowledge, he starts to develop his own unique abilities gaining knowledge (not destroying or hurt, rather absorbing) and use futanari slime. He wanted to create a harem. Imo his power might not last forever. The girls will break free. But Azuza, well it's not going to easy as it seems as the parasitic person wanted her since she got perfect body as a host.
