omg joakkar i would never get angry at u honey //squishes ur cheeks
they areee…. auxiliary characters i guess! to be fair the only people crucial to furthering the anime plot are the kings, and everyone else is just kind of dragged along with it, i.e. all the king’s clansmen, including fushimi and yata
honestly, the first time i watched K i actually didn’t think it was that great at all, and then i rewatched it and got OBSESSED because while the plot centres around the kings and the mystery behind shiro and that whole strand, all these other characters have their own subplots that run alongside the main story arc, and they’re all their own people with their own stories that aren’t just part of the protagonists’!! all the manga and novels go into more detail about the auxiliary characters, and the anime itself is actually really only a small portion of K as a story, and it’s all so worth the read if you enjoyed the anime
in the case of fushimi and yata YEAH LET’S FACE IT they aren’t instrumental to the main story arc AT ALL — yata tries to be helpful to suoh’s cause, and in avenging totsuka’s death, and he succeeds to varying degrees, but fushimi’s character arc runs so parallel to the main plot you have to wonder if he even knows what’s going on, because all he cares about is yata. neither of them did anything of real importance but i don’t think they needed to or were meant to! K is a bigger world than just the king’s and shiro’s story, and fushimi and yata are one of the (more prominent) subplots that run through the series and prove that — they have their own character development and a really agonisingly sad story that gets played for laughs a little bit in the anime, but is actually just heartbreaking because of how their own worlds have just disintegrated to fighting and anger and regret, and neither of them know how to fix it even though they’re both so desperate to have the other back. like you even said yourself — they’re the only ones left fighting because nobody else gave a shit about them; it’s because their stories were about each other, and while their world orbits around the central plot and sometimes overlaps with motivation or action, their development is about their own growth and not how they can be remotely useful to a central plot.
SO YEAH ON THE SURFACE THEY ARE BASICALLY THERE TO JUST BE A HUGE BLACKHOLE OF SEXUAL TENSION, but in reality they’re their own characters that have their own lives, like a lot of the other characters in K! K isn’t just one story — it’s many, woven together to create a whole world.
this is beautiful and explains everything i love about this show and this ship. just fantastic.
