Danbooru の英語定義
Artifact from Mahou Shoujo Madoka Magica associated with Witch (madoka magica)es. Looks like a small dark metal spinning top, left behind when a witch is defeated. Magical girls use Grief Seeds to cleanse the darkness from their soul gem (madoka magica)s incurred by magic use or negative emotions, but it is said that using the same Grief Seed too many times will revive the witch it belonged to.
