the first one would be nice but i think adachitoka wouldnt do that since its a super classic shonen move and they like to be a little more realistic and suprising.
for the second, yukine's nature is super righteous (as we can see in hagusa's powers) and he would never take sides with fujisaki no matter what + being a nora is something to be ashamed of and isnt acceptable, not to mention becoming fujisaki's nora is extremely dangerous. we watched him get manipulated to become his nora, dude. the second part doesnt fit his character nor the story imo
I have a theory that this fight is going to be huge and Yato will not be able to win with Kazuma but HOLD the Fs my friends, cause I believe that in the last moment where Yato’s father draws Yukine to kill Yato, Yukine may come to his senses and help Yato instead! Or there might be another thing which can be that, Yukine actually has been faking all of this changing sides thing and just wanted to get stronger in order to help Yato defeat his father and what is better then going into the lions den? Well the second one is kinda not fitting for Yukine’s character as he usually does things on a whim and always gets into danger or puts others in situations but who knows... I just want Yukine to help defeat that monster of a father!
