Hakushaku Reijou Sarah Cloria wa Kyou mo Akai Ito wo Kiru

"My red thread has been cut!" Suddenly, Alex Hubert, a knight candidate, sees a red thread and learns of the existence of a beautiful black-haired girl who is cutting that thread. She is Countess Sarah Cloria, who attends the same school. She carries a pair of scissors and easily cuts the threads because they are "in the way." She is rumored to be the "Witch of Catastrophe" and is isolated from the rest of the school. At first Alex resented Sarah's selfish behavior, but it seems that she is actually breaking up the relationship between the lovers for a reason...?!
