>>65817181For the fights I'm just linking a bunch of yakuza battle themes. If I had to put OPs and EDs in though, I'd take the Monogatari approach and pick a different OP and ED each chapter based on the characters that appear. It might not fit as well thematically (by that I mean the lyrics and whatnot), but most Holos have made at least one decent orisong or cover.
Shout out to Watame on this, she's made some bangers. Her "Ode to an Eternal Future" would make an excellent ED:
