So for Hikari....<br/><br/>As mentioned, Hikari and Yosh know each other through a mutually enjoyed hobby of shibari, though Yoshi is more likely to be able to recognize Hikari than the other way around. As far as others go, Hikari hasn't traveled much outside of the Dragon Lands except as needed for her Daimyo's wishes. I don't see her having met many Scorpion or Crab and her family and school history with the Crane makes any interaction tenuous at best.
