Oshibato SUPER GiRLS is a Japanese collectible card game produced by Avex Management and tied to the idol group SUPER GiRLS, which was formed through Avex auditions and signed to the avex trax label. The word "oshibato" is derived from Japanese slang for supporting one's favorite idol ("oshi"), and the game functioned as a fan-engagement product sold through the Avex mu-mo online shop. Cards featured members of SUPER GiRLS alongside other Avex-managed idol acts including Tokyo Girls Style, kolme, and WASUTA. Card sleeves with matching branding were also sold separately. No publication date has been confirmed in available sources. Documentation of the game's rules or competitive structure is sparse outside Japanese idol merchandise circles, which is precisely why it belongs in the uncharted archive.
