Aizenkunitoshi Latent effect:?

This has been out for about a year now. I have had one for like 6-7 mos.. Considering I am a ps3 player... I dont think I should have to say how I am unable to figure this out.

So how about a lil help here SE? No one anywhere seems to know how.. Only hint i have herd was from a JP player that said <attack> <up> = 2+ <katana> @ <party>

Took me like 2-3 mos just to get it. And I have yet to see anyone else with one.

Minus the JP player that sold one to him self on the AH but his is never online when I search him...

Would be nice to know the latnet isnt: SE wastes away more time in your life for no real reason...
