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.
Shizuru-san wouldn't intentionally leave 
his book behind if he were the killer.
.ما كان شيزورو-سان ليترك كتابه عن قصد إن كان الجاني
Herr Shizuru würde doch als Täter nicht
absichtlich sein Buch bei der Leiche hinterlassen.
Shizuru no dejaría intencionalmente
su libro si fuera el culpable.
Shizuru no dejaría intencionalmente
su libro si fuera el culpable.
Si c’était Shizuru, il ne laisserait pas
son propre livre derrière lui,
Se Shizuru fosse davvero il colpevole,
O Shizuru não deixaria seu livro
para trás, se fosse culpado.
Будь Сидзуру преступником, он не стал бы
намеренно оставлять свою книгу.
