Bookwyrm released my 2025 in the Books report even though it's only halfway through the month, but anyway, https://bookwyrm.social/user/sachirin/2025-in-the-books
1) 2025 was definitely the year of DanDaDan for me. I got into the series via the anime in 2024, decided to start on the manga this year, and it's safe to say I'll see this series through the end. Volume 22 comes out Jan 5 next year and all that.
2) I feel like my lists every year are padded with manga which kind of feels like cheating?? but I do read prose, and non-fiction, and also in English, they're just there somewhere. I also read and like modern tanka even though I'm not sure what it is about it I like exactly.
3) There are some here that are rereads, like 僕と君の大切な話 and 幸せのマチ etc. They're old favorites that I chose to revisit this year; they'll probably pop up again in some year's list in the future.
