Vezi mai multeMaka and Soul are given a remedial assignment to take the soul of Dr. Franken Stein-who happens to be the most powerful meister to ever graduate from Death Weapon Meister Academy. Needless to say, this assignment turns out to be more than they were expecting. In the middle of the fight, Maka learns how to see someone's soul-and sees for herself just how powerful Dr. Stein's soul is. It scares her so much that she freezes up. Luckily for her, the whole thing is just a set-up as part of the assignment, and Dr. Stein decides to pass them.
Things seem to be back to normal when a more dangerous enemy emerges-and this time it's not a test. Named Crona, he carries the demon sword Ragnarok, whose attacks are accompanied by grotesque, ear-piercing screams. But Crona is merely a puppet of the witch Medusa, who is trying to manipulate him into becoming something called a "Kishin." Shinigami-sama sends Dr. Stein and Death Scythe to make sure that that doesn't happen.
