trying to find an old anime

recently ive been thinking about this anime i used to watch when i was a kid but i barely remember anything about it which is why im having a hard time looking for it T_T i remember guns and this blonde dude who is kind of similar-looking to kurapika from hxh (even his getup, he looks like some kind of priest) its an anime from the 2000s (or maybe earlier??T__T) it came out in the philippines between 2003-2007 maybe ugh idk why i cant get it out of my mind!!! i just need to find ittttt ! it's definitely shounen... and i think they were a group? and one of the dudes uses a gun (maybe a revolver?) help anyone??
