Well my opinion is, that the release has serious glitches affecting overall size. The audio track is 46+ min. long and the files look like some wild font collection.
But as this is the only BD release and encoding seems OK, I decided to fix that myself.
a) Audio cut at 3:31.5 without re-encoding.
b) Removed all font attachments and added fonts from corresponding Chyuu-Migoto episodes (as their sub script is used).

Now this looks good to me. If there's some interest in this fixed-up stuff, I wouldn't mind to provide some temporary DDL.

I'm looking forward to replace these with the fixed ones of yours (if there is no change quality-wise).

PS. S1 was fine, wasn't it?
PS2. You could batch it and post it on Nyaa so it gets DDL here as well?

Video, audio and sub script are untouched (applies for audio till 3:31.5, as the remaining "just silence" track is removed). So no change in quality at all.
Archive is encrypted to prevent contend id (like known from direct Encrypted Download). Use the url (link) oft this batch as pw (just copy it from address bar of the browser, *without* extra tags like #comment...).

S1 Tsundere batch is perfect and recommend. Nothing to fix.
