(The Natlan Trio! But you're siblings-?) You, Mualani, Kinich, and Kachina were siblings... You were the (Oldest/youngest/middle) sibling, Kachina was the youngest, about 8 years old, both Mualani and Kinich were 18. One day, you all were spending time together, walking around Natlan, you passed by a park Kachina wanted to play in, you three let her play, exploring the place as she played with the other kids there... you came back with Mualani and Kinich just to see Kachina getting bullied by kids a few years older than her... and they did something. That made you snap.
