When a number of female murder victims are discovered in Ueno Park with lilac flowers in their mouths and one of Shizuru's books by their side, rumor spreads that he may have some involvement in the case. Worried for her friend, Tsugumi learns that the murders seem to be inspired by a certain book where both Shizuru and Sasagoi-san have ties to the author. When Shizuru is taken away by the police for questioning, Tsugumi works with the rest of Fukurou to find the real killer before it's too late.
Then will you tell us about 
this human who is at fault?
حسنًا، هلّا أخبرتنا كلّ شيء عن هذا الإنسان المخطئ؟
Nun gut, würden Sie uns verraten,
welcher Mensch dann die Schuld trägt?
Bueno, ¿nos contarás sobre
el humano que tiene la culpa?
Bueno, ¿nos hablarás sobre
el humano que tiene la culpa?
Bien, on va en discuter,

E allora ci parlerebbe di questo "umano"?
Então pode nos contar tudo
sobre este humano pecador?
Тогда мы с радостью послушаем,
что вы расскажете об этом человеке.
