On the Sphere Map, the player travels between various nodes, unlocking them by spending Lumina earned by playing songs and reaching certain Sphere Levels.
Named nodes (locations) will also unlock a comic or a playable song. Most of the locations in Sphere Map are real-life celestial bodies, pop culture references, or both.
Some nodes can only be unlocked after clearing the song unlocked on the previous node.
There is also a Sofa.

There is an alternative Sphere Map accessible from Empyreal Bon Voyage in the same way. This is a smaller map which follows Derrida and Endu.
The EBV Sphere Map is primarily for story - the only unlock currently is the "Flash" hitskin.
