Randal's best friend.

Type: Dream entity.

Object-creation/Familiar: Camio

Danger level: Low*

* "Since his true persona only appears in Randal's dreams, to encounter him is already quite exceptionally rare (seeing as how the conditions to meet him is by sleeping within a certain radius (not-verified yet) within Randal Ivory, giving a range of 12-25% chance of dream linking, and even that is dependable on many variables.), then Satoru will also have to be present, which lowers the chances even more considerably so."
