@RimuruEdward6 the problem with writing this cross over is that deadly sins fell off really hard after season 1. Not just animation wise but writing wise. Writing a fanfiction off of a story that was already not the most functional was probably always going to end up this way. Hell, the writers don’t even know what to do with diane for most of the series and just opt to giving her shrink medicines, therefore removing what made the character visually distinct from the others. She had it the worst to me personally and the puppet one (I forgot their name) had THE MOST CONFUSING PERSONALITY I have EVER seen. My advice to you is just make a rimuru crossover with something he’d suit well into. I’ve never seen anyone do a digimon crossover with him for example and there is a LOT of ways to go about it. That should be a gold mine for you if you want to take a stab at it.
