[Crossover] My Ability Is Called [Five Years of College Entrance Exams, Three Years of Mock Tests]

Miyamura Mio, the Port Mafia's most [redacted] member and an undercover agent from the Clam family, is infamous in Yokohama for her deranged, ridiculous ability. Her ability is called "Five Years of College Entrance Exams, Three Years of Mock Tests." It only affects people within her field of vision. Once activated, the victim's mind fills with questions from the college entrance exam question bank, and they start studying right where they are, unable to control themselves. They can't do anything else, including use their own abilities. The abnormal state cannot be lifted unless Miyamura herself stops using her ability. "How did Mr. Miyamura find out about the Book? You shouldn't know so much about it." Looking into the other person's dark eyes, Miyamura felt as if she could barely breathe. A brilliant idea came to her. "Why don't you guess...?" Content warnings: 1. Main character is the bottom, one-on-one pairing with Dazai. Younger partner, with a slight age-gap grooming element. Although Dazai seems like the bottom at first, this really is a story where the main character is the bottom, psychologically speaking, they're in the dominant position. The story opens with a change of leader, and spans a long period of time. 2. A crossover with Bungou Stray Dogs, The Good-for-Nothing Boss, and xxxHOLiC. If you come across anything strange while reading, try guessing what's going on XD 3. Several wildly unexpected, high-energy plot twists. 4. Also updated on HT under the same title. It's a clean romance, with no difference in content, so don't get your hopes up for anything weird. Theme: You are the one and only revelation among all the stars in the sky.
