I was thinking of MTLing it but gave up.
If anyone wants them, here are the raws so you don't need to put up with the original site's abysmal loading times:
If anyone wants to translate this but happens to need pngs of passible quality, I have chapters 1 - 13 and don't plan on uploading the translations I make for myself. Message me and can I'll email them to you or something. Don't have chapters 14 - 18. Sorry if this isn't as helpful I though it would be.
The author said that their initial concept was to have the male best friend as the MC and Aki as the main "heroine" so maybe that's part of why it turned out awkward? The mangaka irresponsibly set up a cluster of unresolved romances toward Aki, and it's impossible to resolve them while Aki is a kid and the people in question are all in college. I realize that the loli element is obviously part of its appeal to many people, but it probably could've turned out significantly better if female Aki was still college-age but just petitely cute; with Aki's personality, she wouldn't need to be a kid for her to have no interest in relationships after suddenly becoming the opposite sex, so the plot could still be essentially the same, it's just that you'd have to cut out her friends who are also kids (and by the way, there's no way in hell that ordinary 6-year-olds act like the professor's daughter Michaela). But I dunno, maybe I'm just biased because Sawada feels like by far the most likable female character.
Onimai (AKA Onii-chan wa Oshimai, the clear inspiration for this work) paces itself better, has less shallow side characters, doesn't rely on convenient amnesia/immature-ification, doesn't randomly tease the reader with lore only to delay it...
But most importantly, it doesn't
destroy the MC's character by having her charisma and likability explained by magic, and her tennen nature explained by the effect of her transformation.
The only non-mundane trait I can recall offhand that she has left (besides, uh, her looks, which are literally copied from some English woman anyway) is her natural kindness toward her best friend (though with the amount he works because of her... yeah). Most of the manga is just her going with the flow, being manipulated by magic, and casually basking in others' adoration that's largely created by magic.
So yeah... I prefer Onimai's lead character Mahiro for many reasons. Mahiro isn't put on a pedestal despite her cuteness, except every once in a while when the boys in her class blush. Unlike this manga's plot which is a mess that will need to rely on more supernatural elements just to deliver a half-assed resolution, Onimai will pretty much turn out perfectly if Mahiro just continues to grow up normally as a girl.
