Episode Title:
Beautiful Enemy.
Episode Description:
A host of Category D monsters appear more and more frequently and the SDCD team have their hands full with their purification, including Kagura who, for the first time, is in the field by herself. Mei senses a higher Category being which she seeks out, finding herself suddenly facing Kazuhiro Mitogawa, a white-haired boy accompanied by a swarm of blue butterflies. They start to fight but the difference in their power is so far apart, that with no effort whatsoever he pierces her with her own weapon. At the same time Kagura faces her friendly school nurse who is attacking her two girlfriends after having killed a man, while been controlled by a Latcher, a mind-controlling Category D. To protect her classmates, Kagura is forced to kill the woman that, only hours before, had cared for her, which causes great turmoils in her emotions.
