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.
But what if Migiwa's been 
reading that manuscript
لكن ماذا وهو يقرأ المخطوط، شعر
ميغيوا وكأنّه يريد قتل أحدهم مجدّدًا؟
Aber was ist, wenn Migiwa wieder mal Lust auf
einen Mord bekommt, wenn er das Manuskript liest?
¿Pero y si mientras leía el manuscrito,
Migiwa sintió ganas de matar?
Pero ¿y si mientras leía el manuscrito
Migiwa sintió ganas de matar?
mais peut-être qu’à force
de relire ce manuscrit,
Ma se Migiwa avesse letto il manoscritto
Mas e se o Migiwa sentir vontade de
matar depois de ler o manuscrito de novo?
Но что, если Мигива читал эту рукопись,
и у него снова возникло желание убить кого-то?
