Maka is about to go on a dangerous Meister mission, one that Soul does not want her to go on. However, she has made it clear that she is going, but before she leaves, she gives Soul a quite unexpected surprise.
Of course, things don't exactly happen as they're supposed to, so Maka will end up dealing with the result of her "surprise" earlier than expected.
Way earlier.
However, it seems that there is someone who is trying to sabotage this mission, and it's up to Maka, Soul, and the rest of the gang to figure out who it is and what they are trying to accomplish.
A new enemy is prowling around Death City, claiming victims. Even the closest of friends. From the same people with the same thoughts, Maka And Death the Kid face this enemy together, and Kid finally learns his true past.
