Might want to add reference pictures next time just in case no one here's played DPPt. But I'm going to assume you're talking about this guy?
The thing you'll probably have the most trouble with there is color. Are you going for a blue, a purple, or something in between?
If you want to do minimal styling yourself (i.e., no dyeing, very little cutting), the closest thing a quick scan of Epic Cosplay and Cosplay.com Shopping's sites turned up is this.
(pretty sure it's the same wig, just lacking pictures)
Something along those lines?
