Actually, you just have to talk with Kupo in Disc 4 and start the whole mail chain. it will end up at... Kupo. XD Then you talk with Ruby in the mini theather, get the Superslick (Supersoft is the one to heal Blank's Petrify XD), go to Mognet Central, give it to Artemicion and you get... a freaking Protect Ring. I was expecting more. T_T
