Haikyuu! reading club is pretty die-hard, lol! They have a nice vocab list. Admittedly, I haven’t read anything (yet) but I really enjoyed watching the series so I’ve been following their vocab list and updating another kitsun deck for Haikyuu generated by the gracious learners in the club, so there may be dialect example there (it’s been a while, if they had dialect examples I probably didn’t recognize them at the time).
Had さすけね and すっぺ but not ねっかさすけね, nice! Will add that one then.
Congrats! An amazing feat, I recall following the your reviews on the 日本語の森 course so it must have been helpful.
