Okay, I’ve read through it quickly, and I am a little disappointed. There are various confused statements and I’m not sure if it’s in the original or mistranslations. Funamizu seems to confuse Street Fighter Alpha with Street Fighter the Movie.
The bios are fairly short and don’t really contain anything new, at least not anything we haven’t already translated. Akuma is described as “evil”, nothing is stated on the briefness of Dark Ryu (it’s implied that he went around like that for quite some time), nothing is mentioned about the SF1 fight except that Ryu won, nothing on Rose’s initial connection with Bison, nothing on what happened to characters after the games (storylines are mostly just like the SFA3 intros), nothing on Sagat leaving Shadaloo (but the relations chart says he’s “temporarily lending power to”), Juli is still T.Hawk’s tribesmember, etc etc etc. A replacement for AAC this is not. Now if THAT could be translated…
So in short, if you have Eternal Challenge already, this book doesn’t provide anything except worse paper and the fact of Cammy being genetically created from Bison’s DNA to hit people over the head with. But at least it doesn’t majorly contradict anything we’ve established (yay for self-glorification) and yes, they kept that Zangief dislikes young beautiful women!
Oh, and it confirmed Rolento Schugerg and Sean Matsuda, if there ever was any doubt anymore. OTOH, it’s pointed out that Rindoukan is the school and style of Makoto, so if it were her last name, they would have said so. Did we know about her “untrained office-worker” brother though?
Edit: One more fact I don’t remember seeing before is Juni scanning Akuma and implementing some of his powers (specifically, the Hooligan Combination and the Mach Slide, i guess). Hugo is also confirmed as a former Mad Gear member (duh!).
Oh, and despite claiming so in the introduction, no translated names are commented on, except Jane/Julia (!).
