If I understand from the extra prelude chapter when the guy wanted to have his way first before the slime did it, this slime is supossed to enter the brain of a host and can consume the brain in order to obtain the host memories and more control over it, idk if the host still is aware also that probably means Miu can be gone for good after the slime proposed the MC that her Aunt can become his forever, only her meat suit would still "alive"
I wonder how this is going to continue, probably the slime leaved a bit of itself in the twintail girl and thats why she regained some control but probably has her reasoning manipulated, otherwise she would have leave the apartment by now and called the police. I hope isnt the first slime because that means the twintail girl is already assimilated. I hope next chapter comfirmes both Miu and the girl state after being parasited.
Btw in page 9 the MC says something about the slime taking form of his aunt, that doesnt make sense contextually i hope this is the only error.

@Ultimates12, in other slime stories by this author the slime simply divided itself into clones who could then infect new hosts for the guy to have sex with. My guess is that something similar happened here as well.
