Bug Fables Team Snakemouth Fight - Rank 0

What is Rank 0? A challenge where under RUIGEE conditions, I cannot equip any medals. RUIGEE is a menu code that prevents me from being able to gain Exp so that I cannot rank up, and by not equipping medals, I'm effectively at rank 0 as I'm playing with starting HP and TP, but not using any MP.
