Thing (心具；shingu) is a family premiered in BSC33.
The family name plays on a pun with the English word "thing". The kanji are "heart" and "object/tool", which can be read as "shin" and "gu". However, when the pronunciations are put together, the reading in katakana also references the English word "thing" (since "th" sounds are phoneticized into "s" sounds when transliterated).
Up until CB09, only Wish Ema has this family. CB09 introduced the "Module"-named Braves, which are Braves dedicated to Kamen Rider Fourze.
