Owari no Seraph #6

The only thing standing between humans and complete subjugation to vampires is sheer tenacity and Cursed Gear. Yūichirō has the first in spades, but to increase the amount of power he can draw from the demon inside his cursed sword, he enters a coma-like state to thin the barrier between human and demon. His power upgrade can come none too soon, as the vampire queen reveals her plans to annihilate the human resistance and claim true dominion over Japan.HQ, comics, mangá
