Honestly, seems really dumb that the hypnotist not only got brainwashed so easily, but wasn't ordered to obey the girl who took control of her; just told her to focus on tormenting the one girl. The mom is supposedly hypnotized multiple times to make her brainwashing sink in, yet the hypnotist (who should have resistance) got done immediately? I don't get why everyone in this story are all masters of hypnosis instantly, and literally only the mom needs repeated sessions to ingrain commands
Anyways, next chapter, the sister who was just hypnotized to be super selfish and not care about her family is about to become everyones master.
