Well, I am not surprised, though it's a bit sad to see.
Maybe next time Ishiwatari will come up with a more palatable format. Nobody seemed to thrilled about it being for 360 or the change in genre. I mean, there's nothing wrong with doing something new, but... Yeah.
Here's a bit of stuff I came across, I'm sure some people will be glad to have it. Translations may not be 100%, though. I'm not sure if the personality and backstory sections are official, something seems a bit off about them, to me.
RAVEN (Seiyuu: Yasumoto Hiroki)
Name: Raven
Age: (He doesn't remember)
Birthday: March 28th
Bloodtype: A
Height: 181cm
Likes: People who make him feel malicious. People who make discoveries and inventions.
Dislikes: Himself, who can love nothing.
Hobbies: Prooving his own existance.
Personality: Though far from a gentleman, he is nevertheless calm and unemotional, and speaks with an air of maturity. While he appears to be gentle, feeling pain awakens his memories of pleasure, and when he enters a state of high tension, his tempermant shifts from quiet to confrontational in hopes of coaxing out more pain. He seems to generally have good intentions, but his loyalty to That Man is unquestionable, despite his own reasons for participating in the incident being unclear. He has a strong interest in anyone who can give his emotions a big jolt.
Backstory: One of the three associates of "That Man", who had previously lead the world into a period of fear. Due to an unknown trick, even if he is reduced to rubbish, his immortal body will regenerate back to full health. He agrees with "That Man's" actions, and is genuinely loyal to him, though his personal goals are unknown.

Sol was once an old friend of his, and the two share an especially deep, kharmic relationship.
