>>53174786The gyaru fashion first started in the 70s having its peak between 1989-1999, Jynx's Japanese name (ルージュラ) is the same as a cosmetic brand popularly used by these girls, and both Jynx and a subcategory of this fashion are based on a yokai Yama-Uba or Yamamba, an old woman from the mountains in a red dress (due to blood in some stories) and golden or platinum hair.
For greater coincidence, Smochun has a haircut and a stylized body to that of the infant Kintaro, a legendary hero who was raised by a yama-uba.
I'm not saying that Jynx is inspired by this, just that both having a common source (Yama-Uba) it's normal for them to look alike.
