Illuminoct is a golden Venoct. He sports a white figure with long, sandy-blonde hair that covers most of his face. A small amount is pulled into a ponytail held with a sky blue band, which matches his visible eye. He wears a pale blue outfit with a very light blue-white material around the waist held with a white band. The lower leg is covered by pale brown material to match his fingerless gloves, while the toed-sandals are gold. Around his neck is a wispy, pale yellow scarf with the tails resembling dragon heads.
Illuminoct is a very high-strung Yo-kai in the game. His last quote before fighting you is, "SHINING~!"
Illuminoct can only be found at Bucklebreaker Station which can only be reached by taking the Golden Happy-Go-Lucky Hexpress, which shows up rarely in the train stations connected to the outside of Gera Gera Land, where he can be battled once a day until he's befriended through the normal method.
