Shirogane (白金 (シロガネ) Shirogane) is a villager of Ishigami Village. She is the mother of Kinro and Ginro and the wife of Tetsuken.


Shirogane is a youthful-looking woman with shoulder-length blonde hair. Her bangs are swept over her left eye and rest across her cheek. Her eyes are quiet large, and downturned at the ends, giving her a soft, motherly expression. Her eyebrows also similarly downturned at the ends, with little variance in the thickness. Her mouth is relatively small with visible lips.

She wears a vibrant green dress with rope tied around the waist, that reaches past her knees. The neckline of the dress is quite plain, with a simple V-neck revealing some cleavage. She bears a very strong resemblance to her youngest son, Ginro.


Abilities and Skills


Shirogane only appears during the second round of the Grand Bout while Ginro is fighting Senku. Along with several other villagers, she is shown giving the sentiment that Ginro should not be chief after he lists his sleazy plans for being Village Chief. [1]

  • Her name contains the kanji for White ( Shiro) and Money ( Kin) which together create "Platinum", continuing the theme of all the Ishigami villagers having the mineral-based names. Her name is a reference to the chemical element Platinum, with the elemental symbol Pt and the atomic number 78.
  • Despite being her son, Shirogane is against Ginro becoming village chief due to his shameless statements during the fight with Senku.
