Runa is a fairy, and a good friend of Chael from Zenonia 3. Together with Chael, she falls through a portal to another world, and must find her way back.

She is quite rude at times, a loud-mouthed fairy, a bit mean & sarcastic and she can be a pain sometimes... most of the times actually but she always got Chael's back. She always supports the boy, telling him to keep on fighting, and reminds him what is important the most. She can be easily persuaded with apple pies.

Not only she gives moral support, she also posses supporting abilities to aids Chael in battle. Once you have your sync gauge filled, you can create a spirit stone by seeing a Spirit Manager in each town. The Spirit Stone provides enhancement to your status (attack, defense, critical, evade etc) and to your elemental abilities.
