You're quint power scale... may be a little off 😀I won't go through each one but...
Nino... Miku called it here... https://mangadex.org/chapter/619772/3 "I'm not some kind of idiot who'd launch a suicide attack despite of having no chance of winning." Nino, "Who are you calling an idiot?" Miku called it saying and she can see... that Nino doesn't have a chance. Nino really didn't argue it either.
I think they both know who is near the top of the power scale right now right?? That's why Miku left it at that and was satisfied she was able to express herself to that point.
In Ch. 85 when Miku pointed towards Fuu and said, "Love/Like," Fuutaro responded with, "Yeah. I know." And then that, "BUT..." If Fuu was able to finish that sentence, he would have rejected her. Same for Nino if she allowed him to respond to her confession at the time but she told him not to respond because she knows it. IMO, Both are out.
As of Chapter 89, the two girls at the top of the power scale are Yotsuba and Ichika.
With Yotsuba, everything is connecting together with these chapters and it all comes down to how the arc ends if she turns on the love switch or if she truly feels like she's been saying through the entire story and at the end of the last arc of how it's ok how it is. I couldn't see it before but I can see where Yots could have mustered enough courage to be the girl that kissed Fuu under the bell.
The first girl Fuu met in Kyoto and the second girl he met in Kyoto.
Fuu has yet to officially find out that Yotsuba was the first girl. And to blow his mind further he then will find out that Ichika is the second girl he met. Even though he probably has an idea because she did tell him they met 5 years ago and I'm sure he's been trying to peace together the truth ever since she later said it was all a lie (remember the chapter where Fuu says he can tell when she's lying 😀)
I just feel there aren't that many volumes left and after this Yots arc, there's still the chapters to reveal Yots and Ichicka as the Kyoto girls and then we need to find out what happened that evening between Fuu and Ichika spending the evening playing cards and what Fuu said for Ichika to have fallen in love with him that evening. And then I suspect Ichika is going to quit school to run away from Fuu and of course Fuu will come to terms with his feelings and bring Ichika back... maybe. 😋
