Konosuba : 7, God's blessing on this wonderful world! [graphic novel]

Arcanletia is known for its hot springs but perhaps even more for its devoted Axis Church following, which is making Kazuma quite uneasy...and he's not alone. Things only get worse when he catches wind of a plot to poison the hot springs--and finds himself up against the toughest enemy he has ever faced! Defeat means death, and after this foe is done with him, even Aqua won't be able to revive him...!
