Let's start with where I left off. Ana had just regained consciousness and is now engaged to Allen.
Due to what happened during her time in the enemy nation and being unconscious, Ana has lost a lot of her strength. With the help and encouragement of everyone at the estate, she slowly recovers.
Allen stays by her side as much as possible, but the ongoing war forces him to attend to the warfront (with more carpet bombing). The nature of the war is akin to a siege on Ramslett, but this is a non-issue since Ramslett is highly self-sufficient.
The focus then cuts to the OG!FMC and her time spent in the royal capital. She's living it up with her reverse harem: lazing around, having sex, ordering the servants, having more sex... you get the idea.
At around this time (details forgotten, sorry) she obtains one of the key items from the original game: the Saint's Staff. While not the literal name of the object (also forgotten), the important point is that it amplifies the powers of its user. Through the use of the Saint's Staff, she begins brainwashing people.
Eventually, the OG!FMC gets her hands on one of the more influential figures within the clergy in the royal capital, which then leads to her dominating the entirety of it. Her clergy puppets then declare her the "real Saint" and the Ramslett kingdom a bunch of heretics. This then leads her to brainwashing basically the entirety of the royal capital, including the trash king.
Tangent: Before Allen and the then-Duke Ramslett went to the audience with the king, Allen warned his friends and fellow adventurers in the royal capital that things would turn to shit fast, and that they should move to Ramslett while they still have the chance.
Anyway, back to the story. With newfound confidence and her desires unchecked, OG!FMC and her reverse harem (I'll just stay Five Idiots for brevity) lead the charge on another attempt to invade Ramslett. Allen begins carpet bombing the enemy like usual, but something seems off...
Usually, soldiers who were severely injured would end up dying, and those that weren't were scared shitless.
These soldiers, however, seemed to keep getting up despite their wounds, and would repeatedly say things like "For the Saint!" and other things to that effect. Fortunately, the enemy force is wiped out (because of the carpet bombing) to the dismay of the Five Idiots, and they are taken prisoner.
The story cuts back to Allen who is going to interrogate the Five Idiots. On his way there, he learns that the guards had moved them to different room than instructed. He chalks it up to a misunderstanding in relaying orders and enters the room.
In the room, the Five Idiots are stripped of their weapons and bound to chairs, in which they sit. Almost immediately, the OG!FMC tries sweet-talking Allen into giving them a light sentence. Allen is disgusted and basically calls the OG!FMC a bitch, taunting her.
In retaliation, the OG!FMC starts gloating about Ana's supposed fate (for those that don't remember: being kidnapped, raped and killed) to try to get a rise out of Allen. It fails, because obviously Ana isn't dead. To the shock of the Five Idiots, Ana enters the room, after which she says that Allen and she are engaged. This enrages the OG!FMC, who then throws a tantrum and complains that she's the real Saint, Ana should've been killed, etc. After she finishes, Allen uses an appraisal stone and is surprised to see the OG!FMC's title: the Witch of Envy.
This is when the OG!FMC's magic is revealed: her words carry a charming spell which influences the people around her. The Saint Staff amplifies this to full-on mind control for anybody who has even a sliver of affection toward her.
Due to his shock, Allen unwittingly announces the OG!FMC's real title and, realizing that she was holding the Saint's Staff behind her back, quickly takes it from her. This further enrages the OG!FMC, who then orders the muscle-brained Idiot to take the Saint's Staff back and kill Allen. The Idiot rips apart his constraints and lunges at Allen.
Using his skills and combat experience, Allen is able to dodge the attacks from the Idiot. Seeing this, the OG!FMC orders the Idiot to instead target Ana, who is still in a weakened state. Allen takes the brunt of the attack and is struck with a fatal wound. Ana freezes the muscle-brained idiot, and the remaining Idiots free themselves and escape.
As they escape, Allen falls to the floor, still holding the Saint's Staff. Ana catches him, and he looks up at her and smiles from the relief at seeing that she was unharmed. He did it. He was finally able to save the villainess. Allen accepts his fate, and begins to lose consciousness.
The scene ends with Ana clutching Allen's limp figure, crying and pleading for him to not die.
