@fitzy64 I think the chapter you translated is already part of the official English. I can't link to the reader site I found it on due to rules but this seems to correspond to chapter 54 of the official translation. A few chapters after this are also translated. Just thought I should let you...
Let's be real here, no one has a chance - this a clear "main girl wins" manga. The other female protagonists are only here to pad out the story for a few volumes.

It makes sense - I imagine even the Japanese audience was getting tired of this extended isekai arc - the conclusion of which had (surprise, surprise) no story development.

I don't know this chapter gave me a very strange feeling. Like we're going to get a "you still don't know who the bride is" final chapter. I hope I'm wrong, I don't like Yotsuba because she only reinforces the tired "childhood friend/promise" trope but an inconclusive ending would be a final...
@Duralumin Thank you so much for all the work you've done over these past few years. I've been following your releases for Otoyomegatari since the beginning and its sad to see them go but I respect your reasons.
