For Those With Experience In Collecting The Alfrex Legend of Sonny Chiba Line, Some Help Please

[p3ss3ssod]

I just picked up a Shadow Warriors Hanzo Hattori from the Alfrex line and it's got a signature on the box. The seller offered no information and it doesn't look like Sonny Chiba's or anyone elses that I can find from the modicum of information about the Shadow Warriors cast/crew on imdb/wikipedia but was thinking it might be an Alfrex employee/dignitary?

I can reasonably safely say it was bought at an event of some description as it came with the original flyer and an 'Event exclusive accessory limited to 100' which is still sealed which makes sense that it was signed there too. But not sure what's in there, so if anyone knows what's in there it'd be nice to know too.

There's so little information online about these figures, I ran out of options very quickly so thought I'd ask in here.

I solved the mystery.
The booklet inside has Ryo Takasugi as the Art Director.

And I must say, even by modern standards, this is one absolutely beautiful figure.
