you guys know this isnt going to get anywhere, lets continue with the Decade talk.
Anyway ill resume. the scan with Otoya and Dark Kivat, judging from what he is wearing, I dont think he will greet Tsukasa with smiles. I'd assume decade must test his strength first against Dark Kiva before getting the K-touch device. You should know that Dark Kiva has attacks that will seriously bring decade to his knees.
Lastly, I believe, if im not mistakened the K-touch (Key-touch) will be the first touch screen device. it involves touching a logo on the screen like display to execute a function.
