i think 431 is just fanfic for the author and the team, but the problem is that for the audience it's a big chunk of disappointment since there is nothing that generally interests us, outside of shipping. Like where is all might? Where's the parents? where's the kid from the previous chapter? How are Izuku's lectures going? How does the mech suit work in action? How are the agencies like?
We get nothing of this, which are infinitely more interesting things to talk about than Ochako's love life, and the little we get is just verbally stated instead of shown.
Well, i see what Hori said in the extra as permission to ignore it, so ignore it i will. lol
Like, honestly, if you like a particular ship then this bonus piece is for you. Other than that, it was... whatever.
I'm rather indifferent to it, but there are bits I did like such as seeing the class be together again and also suiting up to fight a villain. (And of course, Miruko. But why is she isn't higher in the rankings? I still feel she should be the highest ranked female Pro Hero, but I digress. She's #1 to me.)
And honestly, that's what I wished the epilogue would have been more of. Seeing the class together. I said it before, but I was imaginging 431 to be like showing us Midoriya's first day back as a Pro Hero and the rest being bonus trivia, extra information, that kind of stuff.
431 did feel like some fanfiction and something to cater to shipping and even I though I have my ships, I could care less about seeing them in canon. As in I have to see them or else I'll fall unconscious or something--- NO!
I would have liked to see where All Might was and see how Inko was doing. We gotten Present Mic being ranked in the rankings, but how about Eraser Head? Eri? How is Dai doing?
That's why 431, at least to me, felt out of place and not necessary. Because it really wasn't.
I'll give it some bit of grace that it takes place probably immediately after 430 did.
Because that chapter did give up some bits of how and/or where some of the other characters are doing and was left open-ended for the rest to be imagined (which I didn't mind, in fact, all for it)... I guess that is why 431 went the way it did.
Whoever worked on it, I guess felt that way.
