I get it... You tried many plans and feel disappointed to all of them so you choose the original idea.
The problem is that beam is NOT KHH. It does not resemble the anime at all.
Anyway, my friends can help you with that. They can offer your with plans and you decide satisfied or not.
2, Maybe you need a new Read Me so that I can have a complete understanding of your system.
Spoiler: Chou Khh says Hi (click to see content)
I can't think of any khh I've seen that follows the show well tbh. The beam changes style so much in the show. And the Beam is hardly that big of a deal. But if your friends can help out, and make the beams look good in mugen be my guest. just know it needs to be animated right and be fluid. I don't want to retweak the damn khh supers too much.
The system isn't really complicated, picking it up isn't hard at all. I'll make a thread in my board about the system itself and all the chaining and everything I suppose.
