For all that Delta was under/mis-used in the show, the DX Delta Driver is one of my all-time favorite toys. Come on, guys, it is a HENSHIN DEVICE AND A VOICE-ACTIVATED GUN. How can you not love that?
I keep mulling over the idea of writing fanfic about Saya Kimura's time with the Delta Gear, kicking Orphenoch ass.
And no, Keith, the USB sticks are fake; they are sound/light gizmos, not real storage devices.
