It sure shows that U.A. is the world's best Hero School if they allow their students to get away with blatant racism and discrimination without even a slap on the wrist, If U.A. WAS actually the World's Best Hero School then I feel bad for this World.

Ooooh these switches were diffrent than I expected.

At least Kodai should be able to enjoy some nice baked treats. Maybe Sato can even get a "MM!" out of her (her highest form of praise).

Now had it been Koji Koda and Yui Kodai they might have actually been able to go the entire two weeks without saying a single word to one another.

When you think about it, what she wears is probably very important to Hagakure. It's one of the few means by which she can express herself.

I'm not sure which is more disturbing... the thought of Kaminari filling in for Jiro (who's filling in for her own replacement), or the revelation that someone might actually be paying attention to my babbling (these are not deep thoughts by any means).

One disadvantage of having a living, sentient quirk residing inside of him - none of Fumikage's secrets are safe from Dark Shadow (who apparently has few qualms about revealing at least some of them).

But I wonder how Dark Shadow's appearance would alter to match Toru Hagakure?

But will Ashido properly maintain Kirishima's hair? (while the others have seen him when it isn't styled she's the only one who knew him before he dyed it red)

While this is a fun story, my main problem would be that there is no story about Takashi Buraku. While I know you explain hours past in the most recent chapter, I would like to see a story on who he is and how he got to having his crush and bring at UA. Plus, I'm kinda confused on how his quirk works.

Never underestimate the power of glasses to alter your appearance. Just look what they did for Clark Kent (either that or Lois Lane was even denser than Uncle All Might).

At this rate I'm guessing Mitsuki Bakugo will realize that something is wrong with her beloved "brat" within the first minute. And after a rather awkward explanation of the situation she'll probably start apologizing to Ibara as though it's all her son's fault, while insisting that he take proper care of her body (not that he needs any encouragement in that regard - as you said, Bakugo may be rude but he does have standards).

Not only has Todoroki survived many villain attacks, he's also survived his own father's brand of "training". He should definitely be able to survive anything Yaoyorozu could put him through (would those qualify as famous last words?).

I can’t help but think things are going to take a turn either for the worse or for the lewd.

This is going to be one hell of a ride! XD
I'll be honest. I was a little hesitant to approach this story, but so far it's been filled with quality and I'm genuinely curious to see what you have planned for these poor heroes in training. (Especially Izuku and Ochako) ;)

Nejire must have been exhausted - she didn't great everyone with her usual twenty questions. Has Eri been keeping her up late or something?

While parts of Nezu's plan make sense (divide the classes into "swapped" and "not-swapped", and don't require the swapped students to engage in activities which would require either use of their quirk or at least a solid understanding of their body (the change in arm and leg length, combined with a shift in center of gravity could really throw off their hand-to-hand combat skills) while still making them attend their regular classes (although I'm not sure how much Hatsume and Melissa would miss even if they didn't attend class, given how far they already probably are compared to their classmates). However why have swapped pairs share a room together (outside of comic effect)? Aren't there enough empty rooms (especially in the girl's wing) to allow most people to simply move into rooms adjacent to one another?

The part where Izuku and Katsuki predict how their mothers react to the swap! HAHAHHA I do hope Ochako is going to learn about One for All. I mean SHE does have it now as she is in Izuku's body it would also helo them become closer.
