I originally wasn’t planning on joining in, but I like to finish the calendar year without being mid-volume in anything I’m reading, and I have a few volumes I started early this year that I’ve barely made progress in and don’t want to have looming over me come mid-December.
Planned reads:
👘 ハナヤマタ 3巻

I’m over halfway through with about 80 pages remaining. There’s no furigana, but I know a lot of the kanji/vocabulary and have Mokuro for ease of lookups.
Goal: 80 pages.
Estimated time: Maybe an hour?
😨 ひとりぼっちの○○生活(3)

Only about a quarter of the way through, but the series isn’t too difficult even without kanji. Getting through 80 pages shouldn’t be too painful.
Goal: 80 pages.
Estimated reading time: Maybe an hour?
🕵🏻♂️ 名探偵コナン 19

Even though I planned to read one volume per month of this very-long series, I’ve only completed one whole volume so far this year…
The volume I’m on has two complete cases and the first chapter of a case. I plan to read one case this weekend, save the next case for later, then read the final chapter of the volume in December.
The next case should be about 62 pages.
Goal: 62 pages.
Estimated time: Maybe two hours? But previewing the next case, it looks like it may take a little longer than that.
🐷 文春ジブリ文庫 シネマコミック 紅の豚

I originally planned to read two to four scenes per month, but haven’t kept up with it. Pages are generally sparse on text, so even without furigana, it shouldn’t be difficult to make some good progress. I’d be nice to get through about 100 pages.
Goal: About 100 pages.
Estimated time: 30 to 60 minutes.
🌸 桜蘭高校ホスト部(クラブ)(3)

The series that’s way more difficult than it ought to be.
This is the main one I’d like to get through, but I think if I start with it, it will crush my ability to make progress in anything else for the day…
I have one longer chapter and then two shorter chapters left. I’ll focus on completing the longer chapter.
Goal: 61 pages
Estimated time: …two hours?
🌈 虹色デイズ 1

I started this one thinking there would be a crossover chapter in something else I was reading, but it was only a one-page crossover artwork.
After two chapters, this volume didn’t capture my interest, but I do want to give it a fair chance.
I’ll focus on reading a single chapter for now.
Goal: 44 pages
Estimated time: One hour.
Total estimated reading time: 8 hours
Likely I won’t complete all my planned reading, but if I can complete at least one chapter for each series, I’ll be fine with that.
And then there's counting catching up in a couple of book clubs and then keeping up to date on them...
I normally (try to) complete my heavier book club reading on Saturday, but if I’m readathoning on Saturday, the book clubs may get pushed out to Sunday.
