Manga theory: Jelly actually did get possessed/replaced as a child and the Slime is her "actual" personality coming back to roost in her body. That or the reason that Slime Jelly isn't able to recall her former memories anymore is because she's becoming one with OG Jelly, body mind and soul.
Oh, so the hero hasn't had a chance to learn social skills and likely grew up unloved? Yeah, I have a strong feeling that this guy will be a loyal follower of our dear slime saint by the time of the next volume.
was this dropped or is toru scans planning to use another site (tho the dmca didn't seem to affect this series yet) (the thai translation is like 5 chapters ahead)
