Kotoko and Kuro discover where Rikka, his cousin with the same powers, has been living since their last encounter. They go to investigate the apartment, which has a grisly history.
But why this apartment? 
It's like their guilt would've multiplied.
.لكن لمَ هذه الشقة؟ وكأنّ شعورهم بالذنب تضاعف
Aber warum dann diese Wohnung?
¿Y por qué este apartamento?
¿Y por qué este apartamento?
Mais alors, pourquoi venir là ?
Ma allora perché proprio in quest'appartamento?
Mas por que esse apartamento?
Só aumentaria sua culpa.
Но какой смысл заезжать сюда?
Здесь же ему бы только хуже стало!
