Do you think Ichika could succeed in turning Houki, Cecilia, Rin, and Charlotte all against Tabane and their female supremacy world as a whole?
Let's say that once Ichika gets tired of his abusers, and calls these four out on it, he then asks them why they always treat HIM like a scapegoat and not Tabane? I personally believe that it would be plausible for him to say this to these four abusers if he wanted to turn them against the I.S. creator:
For Houki: He would tell her how much her sister just as much abandoned her, leaving her to loneliness and isolation, just as Ichika. Furthermore, he would even ask Houki if she both hates Infinite Stratos AND the influence it's made on the world. Wouldn't she want to fight back against it? If not destroy EVERYTHING Tabane built as revenge for leaving her?
For Cecilia: I don't know much about her parents, but I do know that her father was a lazy scumbag, while her mother was prideful and hardworking, thus making her believe that women were originally superior to men. Why is it that Cecilia's father became the way he did? Was it due to the influence of Infinite Stratos, thus making him more rebellious and not wanting his wife to control him? Or was it because his wife became an utter control freak and treated him like personal property first, thus leading him to rebel? This may just be speculation, but it IS a possibility to consider that could eventually lead to Cecilia turning against Tabane. Even more so once he asks her, "Why is it only women can only pilot Infinite Stratos in the first place? Is it really because they were chosen by the machines? Or is it..... because they were simply MADE that way. Whatever the case is, how can you really say women are superior to men when they need a freaking war machine to dominate and oppress them? If anything, it makes women look less superior and more like f**king cowards who resort to cheating and hiding behind a mech suit, only to act all high and mighty behind their mech suits, but are actually too cowardly to fight them on fair grounds! Am I wrong?" He'd basically be arguing against how the I.S. DOESN'T make women look superior to men, but cowards relying on a superweapon to make men SEEM inferior. Add on to how her father possibly became rebellious to do either her mother's possible change in personality or the fact that she birthed a daughter instead of a son, and his behavior from back then may not have been as unwarranted as she originally thought. All of which could more than likely drive Cecilia to take her aggression out on Tabane.
For Rin: We both know Rin's parents got divorced due to her mother claiming ownership of Rin. This was mainly due to the female supremacy brought from Infinite Stratos, which caused her to look down upon her husband, thus causing the divorce. Rin was then raised alone with a helicopter mom and possibly suffered because of it, thus turning her into the brat she became. Having Ichika persuade her to fight back, and take her anger out on Tabane for everything should not be all that difficult given the circumstances.
For Charlotte: Her father practically threw Charlotte and her mother out like trash, and only sought to bring her back after her mother's death simply because he found a "use" for her. By making her look and sound masculine, and lying to the world about "Charles" being the second male I.S. pilot, it would make it all the more easy for Charlotte's father to gain better intel on Ichika and his I.S. When you think about it, Charlotte has more in common with Ichika then you think. Specifically the fact that they're BOTH treated like tools by their sole older family members and were hardly shown any sort of love or care from them whatsoever. All to help said family members needs related to the Infinite Stratos. Tabane was the one who invented the machine in question, and thus leading to her father to build his own I.S. business. And you know the rest. If anything, it would be all the more easy to convince Charlotte to not just take her revenge on her father for how he treated her and her mother, but also take revenge on the rabbit who triggered it all in the first place, albiet indirectly.
If he succeeds, and they agree with him, then he would give them a chance to prove it by both disposing of their machines AND acknowledging Ichika as their new master. Your thoughts?
