Here's what's available:
Dante Cap (80 MS Points), Beatrice Costume (240 MS Points), Dante Male T-Shirt (80 MS Points), Phlegyas Pet (160 MS Points), Dante Female T-Shirt (80 MS Points), Dante Headwear (80 MS Points), Dante Costume (240 MS Points)
Typical stuff, really. Except for one item -- the Phlegyas Pet. In the game, Phlegyas is a large, molten golem type creature that Dante rides through hell. As a pet, Phlegyas is an adorable little cutie-pie that just kind of hangs out with your Avatar. I've never purchase any Avatar items -- I think the whole thing is a bit silly. But I won't lie, this little guy is tempting.
