A prostitute from Hananoya, O-Taki, has been killed. When Takuboku says, "I saw Kyousuke in O-Taki's room," Kyousuke becomes a prime suspect. Meanwhile, based on the fact that Takuboku's romaji diary was left in O-Taki's room, Kyousuke begins to suspect that Takuboku might have done it. Where does the truth really lie?
We'll just have to find the real 
murderer and save him!
كلّ ما علينا فعله هو إيجاد القاتِل 
!الحقيقيّ وإنقاذه
Also müssen wir den wahren Täter
finden, um ihm zu helfen!
On va l’en tirer
en dénichant le vrai coupable.
Ma lo aiuteremo noi scovando il colpevole, no?!
Basta acharmos o verdadeiro
assassino e salvá-lo!
Нужно найти настоящего убийцу!
