Digimon World Re:Digitize: Decode - Boss Vamdemon 

This beauty PlatinumNemon may be acting all selfish, but the poor thing is just a misunderstood digisoul. As such, it falls upon me to safeguard PlatinumNumemon's new home! I may not have any harlic, holy water, silver and stakes on me, but Digimaru is even better!
As expected of Vamdemon, strong enough to force me to assist Digimaru with items. Truly, that was a magnificent battle! With the base secured, I can start trading for the best items with PlatinumNumemon!
But the story of PlatinumNumemon is not yet over...
