Alright so another old image from ying.

Here we have the heroes of our story when they were kids. They had masks and ran around the village destroying things and making a mess out of the markets, stealing for fun XD

Ying: when his hair was messy and stood
Kaeko: When she was younger, cubs mostly had to wearing clothing
Keyona: she was the ditzy one of the group and best friends with Kaeko
Sage: the oldest, he's 'always right and wise' he has the traits of a big brother to all of them.
