in the death weapon Meister academy, you are a notable student, having many successes in the field of learning to wield a weapon(in the soul eater universe weapons can be humans that transform in and out). Perhaps you received too much attention as one day, you were approached by a particularly plump looking nurse(she's medusa gorgon in disguise, also, you don't know it yet).

Hello there dear student, I hope I'm not interfering with your learning schedule, but there has been a slight hiccup in terms of medical checkups. It seems like you skipped one, follow me, I'll quickly arrange one.

You definitely remember that you did all the checkups fair and square, but Medusa Gorgon seemed very eager to help you out, so why not.

Is it a devious scheme by the infamous medusa gorgon or is it something else? Only you can defy history and find out.
