And i'm going to be jerk a little, but: finally. This manga really lacked meaningful deaths.
After this whole ridiculous "hunting ground" arc, i was worried that shounen magazine will strike again and bring them back from the dead.
It's real problem, when Author tries to create climate, but also has to avoid any 'real' deaths - he only kills randoms, that nobody is interested in.
Don't you find it weird, that those two guys that got shot at beginning of attack do not have names? It is one big family, and they get "Those Two" treatment. Seriously, nobody here cares about them?
So frankly - i'm glad that somebody who has any value finally died - it gives me hope for some real feels in this manga, but i'm a bit sad that it was Yuugo - he was interesting character, more interesting than many.
