Soul Eater, Vol. 8 - Atsushi Ohkubo

Maka is a weapon meister, determined to turn her partner, a living scythe named Soul Eater, into a powerful death scythe--the ultimate weapon of Death himself! Charged with the task of collecting and devouring the tainted souls of 99 humans and one witch, Maka and her fellow meisters strive to master their weapons. While Black*Star and Tsubaki keep Mifune and Mosquito distracted, Sid is able to locate Arachnophobia's demon tool and put an abrupt end to their sinister plans. But though the evil organization won't be manipulating anyone's morality anytime soon, the blueprints for the dangerous tool are sealed away in Shinigami-sama's secret vault rather than destroyed. Surely Shinigami-sama would never think of constructing a demon tool himself?
