>>44241127either a monster of the week format with a changing cast (so you can fuck around with ideas and do cool stuff) or you pick a small cast and you focus on developing them as they move from place to place
taking, say, gen2 (lol) and moving from country to country as you develop relationships with them. However you would have to write it like a jojo-style fight, where you have 3 people screaming on the sidelines and its actually a 1v1 for like 99% of the story.
Otherwise, just rip off mato seihei and have cool battles but have deranged fetish stuff move everything else
