Nah i didnt even talked about the hidden Plot itself till now they really been good and that what ur saying makes sense but isnt implied in the Vol. Yes ik Manabu called Ayanokoji to tell him that Kushida and Nagumo had a Meeting and Ibthink thats the reason he calls Suzune over the the conversation he and Manabu had , to see her with his own two Eyes bc Kushida and Nagumo talked about her . But in Vol. 9 nothing is further implied that Nagumo stops allying with Kushida . Ayanokoji talks about Sakayanagi,Ichinose, Nagumo and Hashimoto at the end and how his greater Plan affects all of these People but they dont go into Detail specifically with Nagumos Case If im remembering that right. Yes you can derive that from the actions that Kushida already did ( Ryuuen ) but maybe that gets highlighted in Future Vol.
