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.
I told you before that my younger 
brother is a fan of yours, right?
أخبرتك سابقًا كم أنّ أخي الصغير معجب بك، صحيح؟
Ich hatte Ihnen doch erzählt,
dass mein Bruder ein großer Fan von Ihnen ist, oder?
Te conté antes que mi hermano
leía tus obras, ¿no?
Ya te conté que mi hermano
leía tus obras, ¿no?
Je vous avais dit que mon frère
était un de vos admirateurs, non ?
Ti avevo già detto che mio fratello
è un tuo grande fan, vero?
Eu já disse que o meu irmão
é um fã seu, não disse?
Помните, я говорила вам,
что мой брат — ваш поклонник?
