She isn't actually related to T. Hawk

But she's a member of the same tribe and her actual name is Lily Hawk?

Edit: It's also unspecified if they're related or not.

According to the Street Fighter Wiki, her name is "Lily Hawk"-
streetfighter.fandom.com/wiki/Lily

The wiki is fanmade, and the source they cite doesn't seem to have her last name. I could be wrong though

Lily Hawk, more like Lily Honking My Cock
