An attempt to make a softsub for the show, in case it might be helpful to somebody:

Raw video here

Please, note that the dialogue at 19:51-20:24 is even more questionable than any other part ^^'

For the file kindly shared on koyama-daily community.

It's been almost 10 months since the show aired, but... #^^#

The sofsub is for the raw video file shared on koyama-daily community.

As always, I'm sorry for the imperfections of the translation, I tried my best #^^#

Links to the softsub:

For the raw files shared here and here, on koyashigedake community. inala-san, happy birthday, thank you for everything!

As a part of celebrations on Shige-day #^^#

The announced 3rd part is something to look forward to, and now could be a good time to re-watch the previous ones ^^
Unfortunately, however hard I tried, these make less sense than newshfan's subs for the 1st Ura File... I apologise for the scenes with some vagueness/questionable logic.

Decided to give it a try ^///^

A couple of details remain unclear, to be honest, but I still hope the subs can be of some use ^^

As much as I hope that it can be helpful, I also hope that some kind soul shares a better version *smiles sheepishly*

Well... I tried. *sigh* I guess I'll leave it here, just in case.
