Cladun: This is an RPG

At the beginning of the tale, a young lady named Pudding and a young man named Soma make their way to a gate that Pudding believes is a portal to the enchanted world Arcanus Cella. They are transported to the Arcanus Cella as soon as they step inside. As you complete levels, you unlock new characters and locations, which moves the tale along. When you clear one story of a dungeon, you gain access to the subsequent levels and, occasionally, a scenario that may allow you to unlock other characters or reveal more information about the existing cast of characters.
