Spectrobes: Origins Unlockables

After you get the third shard talk to the "three shady characters" character that harassed you throughout the mission. Make sure Jeena is with you. You'll be able to link your copy of Spectrobes: Beyond the Portals for the Nintendo DS to unlock these two Spectrobes and put them in your incubator.

Beat the Krux and then save your game. Keep playing on that same save file and you'll see that Silver Komainu is now in your incubator.
