No she didn't, you are right she was never brainwashed to begin with! If I remember she en-spelled the moron so all those "times" he was having NTR sex with her behind Toru's back, wasn't her, either a servant of hers or he was fucking air! It's like that scene from XMEN First Class when Emma used her Telepathy to make that Soviet General think he was having sex with her, when he was just kissing and hugging air while she was sitting and reading till Charles and Erik walked in on that shit!
The only one's brainwashed by that NTR asshole were the Tomboy Warrior and the Priestess! Toru's Ex is the Demon Lord herself! The reason the Priestess keeps getting hit is because "Wannabe" KNOWS that's her default! Unlike the Tomboy who he just had to OVERSHADOW Toru with himself and himself with Toru in her mind to trick her, the Priestess was given the same, however whenever the brainwashing faded her disposition to him (made even WORSE as I suspect she KNOWS she's brainwashed in some form! The worse is he went from "A loser who MIGHT have potential" to as the Male fairy said "A Poop Aura POS with no redeeming qualities!") Shitsoul knows this and it's why he LOVED and hated her! Love in the "he LOVED brainwashing her into seeing Toru in the vein she saw HIM and he knows it! And hates because he knows without the brainwashing, it wouldn't change her feelings towards him!
Tomboy is back at their home, the point of the enslavement to her by Toru was to use the Command Magic to prevent her from taking her own life, understandable knowing her disposition and chapter 1, Asswipe as said made her think Toru was the weakling and kicking him out was the only way to "protect him!" The whole "love ring" was he tricked her into thinking she loved him and only saw Toru "as a friend" hence how she treated him and her "anger" at him fighting the asshole was she thought he was acting "unbecoming!" Because of the brainwashing, when she saw him again, that was the TWISTING making her still think "once time has passed, they can put that event behind them" only once once the brainwashing fell off when he cured it, obviously she had a nervous breakdown because she remembered EVERYTHING, from the SEX which is RAPE now that you know she was brainwashed, to what she said and did to Toru against her wishes
The Priestess was suppose to be a GUIDE to that POS, it's another reason why he hit her near the end of this chapter when she spoke, it reminded him once again what a "tiny dick POS he is" (basically he "doesn't NEED advice, he's the Leader!" her acting out of turn simply reminds him that his position and such are all artificial by his, or more THE EX's design as it's clear KNOWING HER, the Hero need to be in charge and SUPER incompetent for the sake of DEFAMING the REPUTATION of the HERO TITLE ENTIRELY)
Now Ex is a SUPER TURBO BITCH! If you ever saw Dangan Ronpa, you know of it's True Villain, Junko Enoshima! Yeah she's ALOT like her, the bitch LOVES Despair. She PURPOSELY approached and seduced Toru BECAUSE she knew it was ONE option to get Assface to come to her side! Remember he's a NTR asshole! Only way he's approaching her AND empowering that Eye of his is if he's STEALING from other men, especially Toru. It's why he's such a SMALL DICK POS! She didn't HAVE to do it that way and could have done anything else! But she KILLED Toru's parents SIMPLY to leave him in a vulnerable state so she could get to him. She REALLY believed he likely committed suicide after being ejected and dumped like that! So she's ULTRA pissed the man who should have been in the DEPTHS of despair "got back up" and ruined EVERYTHING. Best I will say is when she MEETS her end to Toru, well remember when she MOCKING threw his engagement ring away like it was trash for the POS Ring! Well that action is going to come up and be the result of her humilating death (basically she BEGS for her life, Toru MOCKINGLY lets her dig her grave as she even says she'll "take him back" by telling her to PRESENT his ring.......she is so self-centered that she presents THE RING THE ASSFACE GAVE HER! Only realizing TOO LATE before Toru kills her "what she did with the original Ring!" She TRULY believed back then, that would be the LAST she saw or heard of Toru and never fathom he would not ONLY ruin all her plans, but become the new Hero, in a funny sense, the Demon Noble that Helps Toru get to her pointed this out, she does NEEDLESS things! If she had just SEIZED the assface back then the second he had the Hero Title, that would be it, she didn't need to kill Toru's parents, or "play with him" or any of that shit, she did it on her own, and unwittingly didn't realize "she was playing the HERO JOURNEY with Toru like a fool!" Think about it, some stories have the Hero's family killed by the Demon Lord, which she did! She did a different version of "ruining his life" and then made a FOOL out of him by letting him THINK they could marry simply to tempt the LOSER and make him feel HORRID along with stealing ALL his remaining friends away! And it all lead to nothing! Instead of him DYING a meaningless suicide like she thought or living an EMPTY meaningless existence, he strove and became the EXACT THREAT she tried to neutralize with assface! Basically by her own actions, she made her plans via asshole meaningless, and she died FAR MORE PATHETICALLY for it!)
