Don't you wish you could shoot people through the internet?
Every day anon; every goddamn day
2. The one shooting is an alien robot thing. He hacked the PCs, Smartphones and everything else and just shoot through it. Before doing that he just killed 20+ reporters by holding his hand in the posture of a machinegun and goin "ratatatatatata" at them.
Dude, the story starts with an alienship crash landing on earth, killing 2 people and replacing their bodies with alien robot technology.
Don't think too much about it making any sense and enjoy it.
As far as I know it's just the mangaka having a proxy-by-manga revenge on the guys who bullied him at school or on internet.
Still, the manga is good in itself, I guess, but it feels a bit pathetic when you know why he's making it.
