First is with Kamen Rider Ghost's final form, the Ghost Mugen Damashii (Trans. Ghost Infinity Soul), which he activates thanks to the Mugen Ghost Eyecon. Next is Kamen Rider Specter's final form, Deep Specter, which he activates using the Deep Specter Ghost Eyecon.
Lastly, a movie tie-in Ghost Eyecon, the "Kamen Rider 45 Ghost Eyecon". There are no other details about this rumored Eyecon aside from the name. Take note, the third quarter toy catalogs will be out within this week, expect scans that will confirm or debunk this set of rumors any time soon.
