Some fan arts of Shiki depict Natsuno with a turtle:

- https://www.zerochan.net/808391 (turtle reflection in the glass of wine)

Also, Natsuno's father is shown with a dead turtle in other fan arts.
I've only watched the anime and I'm really curious.
Is there any explanation for this, something in the manga or novel?
