I knew he was gonna throw his gun! Bit of a weird way of throwing it, though, but hey, he did it! I think Bochi just wanted an excuse to draw a bunch of cool scenes across two page spreads, and I'm all for it.
I think I'm gonna drop this manga. It's very not Boichi-like, except for a couple of panels with the iconic camera angles and facial structure. Even those lack compared to something like Origin and Sun-Ken.
