An [[orb]] with the appearance of a [[yin yang]] sign.

[[Yin yang orb]]s are commonly associated with [[Hakurei Reimu]] of [[Touhou]], since they are one of her main weapons, but they're not exclusive to [[Touhou]]. They were apparently constructed by the craftsman goddess [[Tamatsukuri Misumaru]] in the distant past.
