Well, I read some people complaining and kinda underestimating this manga and its characters. So, let me tell you, how amazing Nanairo Kakumei development is. It's certainly a spoiler, but I'll refrain myself to tell the details to not spoil the fun. This manga is full of twists, after all.
Volume 1
"Nana's Revolution Starts" Arc
About how Nana decided to change and be herself. Thus, the problems come...
Volume 2
"Yuyu's Showdown" Arc
It have already started from the vol. 1, actually. With this arc we can see what Yuyu capable to do. Damn... she is a genius manipulator. And though not explicit, you can see her true purpose. By the of end this volume, Nana is distancing herself from Yuyu and friends, chooses to be a loner.
Volume 3
"The New Friend Part I" Arc
Nana meets another girl in the another class, Himari and becomes friends with her, turning on Yuyu's yandere mode.
Volume 4
"The New Friend Part 2" Arc
Both of Nana and Himari is looking for the truth of each other, thus, they become "true friends". Yuyu's plan is failed. One important note, in here is the last time Shioka helps Nana, it's just she becomes strong that Shioka doesn't need to come anymore. Also in here, you can see what you have been hoping for, the drop of Yuyu's mask. Though, it's done in a way you will never expect. Really, Yuyu is not one character to be hated, she is one to be feared. All the characters, Nana, Yuyu, Shioka and Himari, they are so amazing here.
Volume 5
"The Confession" Arc
Yeah, it's a romance development story, and more Shioka. But if you think it finally become more like normal shoujo manga, you're wrong.
Volume 6
"The Confrontation" Arc
Can you see the cover is so different from the others? Without any hidden tricks, without any manipulation, it's a "direct confrontation" between Nana and Yuyu. Finally, in here, you can give the tables freedom. It's also around here, some readers stop hating Yuyu and actually come to like and support her. Many agree, Yuyu really is the best antagonist in shoujo manga history.
