The four chapter Raspberyl side story is now on the US PlayStation Store. Each episode costs $2.99. Alternatively, you can purchase the entire Raspberyl acting as a teacher arc for $11.99. Here’s a video sample of what you get.
In case you haven’t been keeping up with all the Disgaea 3: Absence of Justice downloadable content (totally understandable, there is a ton of stuff) this is a list of everything available in North America to date. The only items we’re missing are Toro (aka the Sony cat), Emperor Royal King Dark III, and Plenair. Buying everything costs around $60, which is more than the price of Disgaea 3!
