A lot happened in this volume, and it went quite in a different direction from what I expected.
Thanks to Yumina's noble sacrifice (?), Alpha is no longer concerned with Akira becoming close with people, so I'm not so worried anymore for what might happen to Elena, Sara and Shizuka.
Akira keeps getting stronger, and funnily enough this is making Alpha stronger too since she can go all out with her support. The other characters too got some upgrades, especially Sheryl that is making big money.
Nice character development for Carol, who is back being an hunter rather than a prostitute, and earned a spot among Akira's close circle.
Udajima turned out to be sliiiightly less scum than believed, but I'm not going to cry for his death. Wish Akira killed Viola too, but I supposed she's here to stay until the end.
Not sure what will be of Shirou and girlfriend, are they going to become antagonists or allies? I vote for the latter, but who knows. Best outco,e would be fir them to work with Akira in a way that makes Sakashita happy and allows him to keep the fancy front line gear without having to kill them.
Alpha's goal seems definitely to bring back the old world, but if that's a good thing g or not, we still cannot tell.
