So much of your post has literally nothing to do with manipulation. I know you have your interest in who is and isn't the best girl. But in case you haven't noticed, I didn't say anything about 'best girl' in my post. Now while she isn't necessary telling him the entire truth (how much she is actually hiding is unknown even to us) that doesn't mean she is actually manipulating him. Because for one Akira is aware of the fact that she could be lying to him. He's cross checked things she's told him before with other people. He is -choosing- to believe her with out question. But he also isn't just assuming everything she says it right. Nor is she actually trying to change his decisions with deception. When he disagrees with her she presents the facts and lets him decide. This has happened number times.She's 100% manipulating him. She presents information in ways that purely best benefit her and omits other details that work against her. She freely states many times (to herself) just how much she wants to understand (and therefore gain control over) his thought processes.
Yes, she is assisting him and he would be dead if not for her and there's undoubtedly a lot of necessity in many of her actions but do not mistake this for benevolence on her part. Alpha's worked with hundreds of people before him - she's built up many ways and means of subtle deception and redirection over the years so she can more accurately utilise them.
She would quite happily rip apart his relationship with, for example, Shizuka, Elena and Sara, three people who legitimately want nothing but the best for Akira and who make him happy, solely because they represent a threat to her total control over him - he will often briefly prioritise them over purely completing her mission.
She only doesn't do so because she hasn't yet figured out how to without damaging her own relationship with him yet, which is the one thing she fears because it could mean having to start again from scratch.
Alpha is absolutely the best thing to happen to Akira but she is not human and has her own agenda and that includes removing Akira's agency as much as possible.
Mostly see above. But "Withholding infomraiton" is not always manipulation. Manipulation is trying to control how a person thinks. Keeping a secret is not 'manipulating' someone. It could result in a change in their decision yes, but that's not 'manipulation' that's simply keeping a secret.He seem to agree with alpha because he only know what alpha tell him. and that's what we call manipulation.
she didn't isolated him because that's also her way to learn his way of thinking so she can better manipulate him.
for better or the worse alpha is AI with purpose, while alpha probably has no malice and Akira also really need her help what she did still amount to manipulation.
its quite clearly implied in the way that alpha did not share critical information like how the access permission actually work and using excuse that its too long and complicated to explain. this only become clear when Akira meet the other management AI later.
well I can understand why she using manipulation tactic here because her previous contractor either die before they completed the task or "betray" her by abandoning the task.
I do agree that she is hiding things and trying to learn about him, But I don't feel like she is actually trying to control him. She wants him to side with her yeah, and she is picking and choosing what to tell him, but when push comes to shove she always gives him choice. And yeah you could say that maybe that's part of her scheme, but I feel like they would make that move clear if they wanted her to be manipulative. (That's just my opinion.)
