Slightly better than the first volume, though the second story of the first volume sure is memorable. At least fortunately in this volume there is no such 'easy-to-shout-black-or-white-character' as Sakuma in the first volume (glad he's not returning, lol). There are two stories in this volume where the second story is still continued to the next volume. The main POV characters for both stories are D organization's Spies.
I liked the way this espionage story keeps it low-profile, still offering the quiet and rather realistic spying activity, well, for a manga story. There's not much actions or such things that draws attention like in spy movies.
The way the characters drawn is also quite appealing: the expressions when the spies acting like ordinary people, then when in their spy mode, and the way some faces are just interesting especially for both antagonists (Marks is notably strangely scary).
It's too bad that there are only 3 volumes for this title series, as it's started to get interesting and showing some more potentials (the first volume feels like mostly an introduction to the D's espionage world). I want to see a POV from the victim of D's spies or a larger main story.
What makes me hesitate to give it 4 stars, is that I believe it can be better. I believe there are many plot holes, and the absence of background story which can make the story stronger, but it's an enjoyable espionage reading regardless.
