Kimizuka is approached by Nagisa Natsunagi, a girl with a yearning seemingly inspired by the heart she received in a transplant. When Kimizuka asks Fuubi for help, she takes them to meet an unexpected someone who provides surprising information.
I received life from this heart,
so I want to pay back the favor.
،تلقيتُ الحياة من هذا القلب
.لذا أريد ردّ الجميل
Dieses Herz hat mir ein Leben geschenkt.
Recibí vida de este corazón,
así que quiero pagarle el favor.
C’est grâce à lui si je suis en vie,
Recebi minha vida com esse coração,
então, quero retribuir o favor.
