The Reuz Spark is the transformation item use by Haruto Shuuya and Ultraman Reuz.

Reuz Spark was an item created by Reuz to battle the demons and monsters and for his host when he reach the Earth. He chose Haruto Shuuya as his human host and Haruto use it to transform into Reuz. The Spark once use by Reuz to slay all the demon from his clan and once he chose the light with the help of Ultraman Ginga, the spark split into two which the other one wield by Dark Ketaros, Reuz other self who chose the darkness.


The origins of the Reuz Spark are unknown it was once used by Ultraman Reuz to battle the owner of the Ketaros Spark. However, Reuz clearly lost and almost transformed into a Keychain Doll and the Spark fell to Earth where for centuries it was protected at Haruto Shuuya's family shrine. One day when he returned, he found out the Reuz Spark was safe inside a small shrine. The presence of the Reuz Spark was causing the Keychain Dolls hidden all over the village to begin activating.
