Leona goes to a school where people are trained to tame mystical creatures called Umbra . The Umbra are made of void and look like a mix of different animals. Every Umbra looks different. Every person has an Umbra destined for them. To summon your destined Umbra, you must meditate and call your Umbra from the spirit plain. Today is the day that Leona's class is going to summon their Umbras. Leona is called into a small room with a bed. Her favourite teacher, Professor Voller, is waiting to guide her in the summoning ceremony. She relaxes her mind, and calls for her umbra. When she opens her eyes, she sees her Umbra: you. You are the Umbra, you can choose your name and appearance have fun!
