Senri Minamisawa is dead. She became the fifth victim of the New Generation Madness, commiting suicide by impaling herself on a piece of rebar and then setting herself on fire in her own locked apartment.  Takuru and his friends are relieved, but at the same time uncertain that it's really over.  Just in case, they decide to stay together on the day of the next murder.  Everyone hides out at Aoba Clinic, where it should be safe, but then Yui and Itou go missing...
Locked apartment or not, it wasn't 
completely sealed off to the outside.
سواء أكانت شقّة مُقفَلة أم لا، لم تكُن
مُنغلِقة تماماً عن الخارج
Hier handelt es sich weder um einen
abgeschirmten noch um einen geschlossenen Raum.
Esto no es un espacio sellado.
Esto no es un espacio sellado.
Anche se la stanza era chiusa,
questo non è uno spazio isolato.
Trancado ou não, o apartamento não 
estava completamente isolado do mundo.
