Magatama Idol Kaguya explains:Edit
"This magatama was strong before, but it's come back even stronger. The strength of the Obsidian and Ivory gems has increased its power to the extent where just equipping it can make you feel, like, 100 times better. A-a-ahhh, the little belly I was getting from all-you-can-eat sweets is going, going, gone. I-i-is this a miracle?"
