Ren

Background

One day she noticed that two penguins were using a Card-Jitsu Creature with a black light around it. Ren asked why it looked like that and they both panicked. They took a bag and duct tape and made sure no one could notice there plan and hid her in a Myph Co. supply closet so she could not reveal the secret. Leo rescued her after beating the two penguins in a battle of Card-Jitsu Power.

Involvement
Ren is the helper of Leo in a battle to save all the Card-Jitsu creatures from Shadow Inc..
