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.
In the end, I'm no different 
from that killer.
.في النهاية، لا أختلف شأنًا عن الجاني
Am Ende bin ich nicht anders als der Täter.
Al final,
no soy diferente de ese culpable.
Al final,
no soy diferente de ese culpable.
Finalement, comme ce meurtrier,
Alla fine, io non sono diverso dal colpevole.
No fim, eu não sou
diferente daquele criminoso.
Я в итоге ничем не отличаюсь
от того преступника.
