Karasuki

is a turtle-like artefact.

Trivia

 * Karasuki, like Urashiki, is inspired by the tale of Urashima Tarō, in which the fisherman Urashima rescues a turtle which carries him to the Palace of the Dragon King as thanks. There time passes differently, and when he emerged after only a few days of feasting and entertainment, he found that a hundred years had passed for the outside world.
