Rainbow Realm

The Rainbow Realm (虹のプレーン, Niji no Purēn, Plane of Rainbows) is a realm that represents the element of Rainbows in the expanded lore of Magical Vacation. It is only ever mentioned in the complete guide, specifically in the descriptions of the Magic Set equipment pieces.

According to the complete guide, the Rainbow Realm can only be accessed by a faction called the Emissaries of Rainbow. Wearing the Magic Set is what allows them to enter it.
