I want this to have a huge build up, complete with mini flashback of the second protagonist. I want the hype to be so strong that even people who don't read this come in just to catch a glimpse of the glorious confrontation that puts every other battle manga to shame. Angels will weep and sing a beautiful song, signaling the start of a battle that will shape the very existence of their made up world and ours.
I then want it to be over in a single, small panel.
