@neet101: Considering that she's this arc's villain by virtue of being revealed within two chapters of her reintroduction, then having an entire chapter dedicated to her situation - yeah.
I understand why she's gone to the deep end but her methods and approach is where I would draw the line. She'll cause a lot of senseless fighting even though the Dominators and those that hurt her and Folka deserve their just desserts. The introduction of these Dominators will probably put Midori and most of her faction on their personal shitlist, things will get complicated because Midori is justifiably blinded in anger and hatred. (For someone who uses logic and smarts, she's already making terrible short term choices.)
Since she's gassed Mashiro, Hibana, and Folka to sleep; Midori probably intends to keep them alive for the sake of developing a means of controlling the giant robots.
