Tokyo: Their Characters Collapsed Again

My name is Shirakawa Yu, I am 17 years old and a student One day I gained a wonderful ability, and I could be rewarded by correcting some twisted and unusual personalities. Do you think I will become a psychological counselor because of this? Wrong, very wrong. Not only was I forced to learn psychological counseling, but I also had to master philosophical thinking, singing and dancing, kendo secrets, gun shooting and even... Cat behavior modification. Because my correction target is: With Fudo Meio tattooed on her back and two Glock 42s in her bag, she is known as the "Worst High School Girl in the Country". Known as Yamato's genius beauty, she looks gentle and sweet, but in fact, she lies constantly and enjoys playing with people's hearts. However, she has a serious self-destructive tendency. There are also [voiceless idols] whose vocal cords were damaged in an accident and their futures were ruined. Does this one look normal? No, my mission is not only to get her to talk, but also to help her return to the stage and become a super popular star. And... The [sister] who used to be cute and cute, but has been acting strangely lately.
