Spirit Orbs

The five Spirit Orbs were really in-fact the Master Puppet's will for manipulating the three Shirogane clan members so they can search for the Spirit Orbs and bring about the revival of the Master Puppet.

Appearance
The spirit orbs themselves were very large spherical orbs in colour, that is until they had lost their power from the destruction of the Master Puppet and became some-what very small in the end. There were a total of five spirit orbs in existence: red, blue, green, yellow, and pink.

Trivia

 * How the five Spirit Orbs became small after the final battle with the Master Puppet, remains unknown.
