Reckless falls short, she's ruthless. Or rather, merciless.
That look of hers speaks for itself, Hana knows and literally wants Aya (and Kaede) to get wrecked.
Like I said several chapters ago... the dynamic between the twins is going to change now that they are rivals.
Aya could always count on Hana to have her back.
Now Aya should better watch her back with Hana.
Going back to what Hana thought back in class - not telling Team E about Ruri. That would only work if Aya and Kaede either agree (and they likely won't) or are out of commission. But will that actually work? I have my doubts.
Maybe Suzuki asks Sou's team to escort him home as well, because his own guards seem to have lost it
