What I wrote about the first volume still applies. Somewhat predictable outcome, but totally satisfying anyway.
There are a bunch of chases (or just following people around), kidnapping (or something like it anyway), sudden trip to London, men-in-black (non-)actions, and lots and lots of people. That last one is inevitable since there's a Comike chapter in this volume.
After all that confusion, Haruka's mother's, umm, graceful first appearance really put a satisfying smile on my face. She makes clear who the main TSUNDERE character is in the Nogizaka family.
