I really don't understand how show where characters die extremly stupid ways just for the sake of plot and "feels", while you don't even know them that good to feel anything can be called "master piece". The only death that i felt sad about is that masked flame thrower guy. And lion-girl death was the most dumb death i ever seen. Get's shot in stomach - walk's around talking with everyone and watching parade - dies in some corner with drammatic camera zoom out.
It's not seinen, it's just shonen, but author has tradegy fetish. Their death wasn't even realistic to care. I watched it 3 times, and still didnt get what's so good about it. Well what to expect from people who think "houseki no kuni" and other yuribait bullshit is aoty.
