The story begins with the main character, Hirotoshi Hanagaki, a young man who is very talented at crafting. He comes across a mysterious message left on his home. It turns out that this is the home of a secret base called the Vault. The message says that there is a secret hidden in the Vault, and that the secret will be revealed to him if he finds it first.

He finds the key to the Vault in the form of a strange, glowing egg. When he cracks the egg, he finds that the egg contains a magical, glowing life-form, called a 'Eggotium'. The Eggotium then hatches into a small, glowing creature, and calls out to the player, asking for help.
