Material Realm

The Plane of Material (物のプレーン, Mono no Purēn) also called the Material Realm is the neutral realm of Kovomaka in Magical Vacation.

In Magical Vacation
The only places that can be explored in the Plane of Material are Will-o'-Wisp Academy and Valencia Beach. They can never be returned to once the prologue ends.

After a battle took place 300 years before the start of the game, Biscotti defeated Kerendu by taking control of the strongest Enigma, Yuvek. With his reputation in shambles, Kerendu swore to never lay a hand on the Plane of Material ever again. However, that slowly began to change around 285 years later as chaos returned to the Plane of Material. A second battled occurred that ended the lives of many soldiers, so as a precautionary measure, Biscotti became the founder of Will-o'-Wisp.
