lol, Miku this chapter compared to Miku last chapter... like night and day.
But that attitude is understandable. If you act as a condescending, selfish bastard like Yamada did and treat her as a servant or slave then Miku would react cold and annoyed - obviously. It took Sou to actually get through to her and dissolve the insecurities stemming from her appearance. For Miku who only experienced prejudice and rejection because of her looks and usual attitude, having someone actually liking her for that is some sort of salvation. She's still mostly the Ice Queen, but when it comes to Sou she's willing to act girly and sweet. Must be quite the shock for people who know her. If only she wasn't starting to become like a drug addict on withdrawl when Sou isn't near...
Also, class chat. Some of them are easy to identify... like Yuri and Maria. The Dogeza Duo is probably in as well, although it's not 100% clear - I guess it's those worrying how to get close to Sou. Probably Classmate A and her seat neighbor, or the girl behind her as well. We should be getting some names during the welcome party, hopefully. It's due.
You are wondering about new Girls?
I would assume we might get to see/know Ruri's team before more girls from class E get officially introduced.
It could very well be that the D-Team intrudes on Aya hugging Sou.
And as always, thanks for the clean version
lol, seeing this colored one, it looks a bit as if Sumire snuck into class, sitting in front of Miku... though the hair color is not dark enough for her to be Violet-sama

Would be funny though, Sumire infiltrating the academy should happen at some point as well, because she needs to inspect her Ottouto's learning environmant.
