Well , there is one thing that does not make much sense if your theory is correct...If Shirohime and Helen had that grand type of plans, Why does Shirohime has hired Nanali to her new found company, the Zaibatsu, while she could easily have her killed for her change of testimony...I mean the fact that Nanali knows all those things that happened is dangerous for Shirohime and Helen and not only for the "law" that snoops around them but for Headmaster's family to hunt them down for revenge...I mean that Helen is not too bright as lilith or Rachel said but I don't exactly think that Shirohime and Kaya have not made the connection... Especially Kayane has probably figured out the real Identity of the MC , I mean the 1st day Tochiro was the guy that said "new blood arrived, i think he is Sheila's step brother or cousin or something" I always wondered why Kayane hasn't make an investigation about MC to be able to determine if he can be an ally to her goals or not...
Yes, it's an incomplete theory. It would be, it would be a formula. That said, and now that I no longer have any doubt about the identity of the third daughter, it makes sense that she is at Shirohime's side. Why is Nanali still alive? She only withdrew her testimony against the father, she did not testify against or denounce her two classmates. Why does Shirohime trust her? Because Nanali is in debt to her boss. We can assume that when Shinji and Nanali's parents died, Shirohime proved to be a great help, financially and playing the emotional card. Medical care taken care of, Shinji gets his entrance to the academy and I don't know what else, but surely enough to gain the loyalty of his old classmate. Moreover, she already knows the big secret, which avoids the risk of this secret being discovered by another nosy employee. Anyway, Nanali is alive, and if it hasn't been confirmed by the plot yet that she's indeed the third girl, it's certainly more effective to keep her around and buy her loyalty than to let her wander around, at the risk of finding her dead drunk and desperate in a nightclub, saying all sorts of compromising things. I know. That makes Nanali an accomplice, which I don't like at all.
For everyone, the MC is Tomoe's son from another relationship. I'll grant you that it's a little sketchy that Georges takes this boy in right after Father Sazaki's death.
Shiro is too preoccupied with his own business to make a connection, even though she came close to busting him with her investigation into the MC's past.
Kaya? Hah, Kaya is cautious and her approach to the whole situation is that of an analyst—nothing to do with her asshole, okay?—and knows that the MC is no ordinary student. Even if she discovered his true identity, why would she go around reporting him to her sister, probably his worst enemy? She's gotten really close to the MC, and she knows he has a thing for the Musashima girls—yes, I know, he has a thing for anything with a pulse and a pussy—but with Motoko, there's something more, and this brilliant girl doesn't miss that kind of detail. If, and it's still a big if, she is indeed involved, even responsible for hiding the missing parents, she and the MC have goals that align.
Case of send the boy out to do a mans job......probably. However, if its for MC to get closer to Shinji sister Nanali then worthwhile imo

time will tell....lots of time...lots and lots of time
Hey, now, don't be so sad,
2035 n'est pas si loin Edit: (Oops, sorry, I sometimes get mixed up with languages). 2035 is not that far away. Anything is worthwhile in digging around and on Nanali and there is a lot of digging to do *Squish squish*. In any case, getting close to Shinji is not worse than being around Kensou and could be another way to poke deeper and unnoticed. ho my, a lot of poking and digging with this meaty girl.
t seems to me, or it just seems to me, that MC has a soft spot for Yoko. Otherwise, why would he stick to her in the pool when he lost his clothes at Yoko's whim? well, now he's offended by her and has a thirst for revenge, although he already keeps her on a leash, but nevertheless, it was nothing more than the "taming of the shrew" by Shakespeare, wasn't it?
in other words, no, Yoko has become MC's "arson bitch" and is not subject to the humiliating fate of pole work, she is his personal toy
MC has a lot of soft spots for a lot of girls. One pulse, two legs, and, well, you know...
But, would pole dancing be more humiliating than their brutal sex camshow? And depending on your choice, during the first visit to her place, he was already sharing her with the two thugs from the train. In leash, yeah, but his personal pet? If he should share one of the girl, that would be her, imao.
Imagine the club's success with a rising porn celebrity pole dancing. The MC has already managed a prostitution ring as accountant. Do you see where I'm going with this?
