|This article is about a/an set of alternate forms in Kamen Rider Ghost.|
Decade Damashii (ディケイド魂 Dikeido Damashī, lit. "Decade Soul") is a Legend Rider form based on Kamen Rider Decade. Accessed through the Decade Ghost Eyecon, this form bears a currently unknown helmet with a currently unknown faceplate. The Kamen Rider is armed with Decade's Ride Booker in this form.
As one of the 16 Heisei Rider souls, Decade Damashii's power is also channeled through the Heisei Damashii which is accessed by Ghost via the combined Kamen Rider 45 Ghost Eyecon. In conjunction with Blade and Ryuki, it grants Ghost the power to create energy projections of their respective cards.
Created through unknown means, the Decade Eyecon was among the first ten Heisei Rider Ghost Eyecons which were possessed by Freya. After having Kamen Riders Ghost and Specter collect the following six Rider Eyecons, she combined all sixteen into the Kamen Rider 45 Ghost Eyecon, which would later be used by Ghost to assume Ichigou Damashii as well as the combined Heisei Damashii, allowing him to defeat the revived Nova Shocker generals Urga and Buffal as well as the Alexander Dark Mind.
