Vol. 2 ch5 has one of the best coop action scenes I've seen in a long time. The characters' movements, their personalities, their design, the atmosphere, the backgrounds, the side characters, the way they build their relationships, it's all very nostalgic yet new.
Was very VERY sceptical about reading this at first, however I do not regret one second spent on reading it. Wish there was more, but guess I'll have to be patient.
