I think I remember the tenzen sword effect was bound to the hand, and when you tried to weigh it onto a weapon it would be rotated 90 degrees so it would be horizontal to your sword >< and since that was one of those mysterious emitting effects I could never really figure out how to rotate it since it would just rotate the particle effects
As for Kayu's DAT im trying to figure out what this nulp is that the effect is calling for. Its in the place of where it would be calling for model data (and in turn texture) but there is no model data with the nulp header. I checked 0.dat and there are also nulps being called there, however, again no model data.
Are you sure vb00 is the effect data you're trying to attach? (sorry this is harder without being able to altanaview ; ; )
