Doku Doku Doku

Nazim Fuwa is a high schooler who, due to overworking himself at his part-time job in order to provide for his family, has very little hope for the future. Living each day like this while unable to see a light at the end of the tunnel, he says to himself, "I wish a monster or something would just completely obliterate everything." After making that wish, he encountered a beautiful girl named Kou Tsukino, who's also a truant. And now, he's seething blood and brimming with life. This young man will become a monster!
