I hope I haven't misinterpreted Boss's "サンドスターによってフレンズ化される種の区分はしばしば曖昧で" here, but it sounds like he's invoking the "rule" that there can be only one Friend per species at a time. Otherwise I don't see how the concurrent existence of Red, Ezo and Silver Fox would be a source of puzzlement.
Who?In the JungleCould she be a close relative?The boundaries between species transformed by Sandstar are often vague.There are still many mysteries.By the way, Red Fox,you look a lot like Ezo Red Fox and Silver Fox!They're our friends from the Kyōshū Region!The Ezo red fox and silver fox are subspecies of the red fox.
