Otome Game no Hametsu Flag shika Nai Akuyaku Reijou ni Tensei shiteshimatta...

Synopsis

Mimicking the judgment event from the game, Catarina is accused of bullying Maria, but Maria and the others vouch for her innocence. Although Catarina is relieved that she has evaded a major doom flag, Maria goes missing after investigating a dark aura coming off the instigators. Three days later, Geordo discovers that the list of "evidence" the instigators used against Catarina was not actually written by them, and that they themselves have no memory as to why they accused her. He suspects that they were being manipulated by dark magic, with Maria's ability to detect it leading to her capture. That night, Catarina has a dream where all of her friends die and is unable to sleep. Fatigued the next morning, she takes a rest at the infirmary. As she walks back to class, Catarina sits down on a bench and reminisces her first time meeting Maria. However, she is interrupted by Sirius Dieke, the student council president. Recalling what Atsuko said in her past life about a hidden character from the game who possessed dark magic, Catarina soon realizes that the true culprit is Sirius, who declares his hatred for Catarina and puts her into a slumber.
