I love the Honzuki no Gekokujou: Shisho ni Naru Tame ni wa Shudan wo Erandeiraremasen manga (yeah, that's the title). It's really interesting and the main character is such a cutie puff. It's isekai but it's different than most because, instead of a powerful fantasy hero, the main character awakens after her death on Earth as a sickly little girl in a commoner family in another world. As such, when she learns that books, which she loves with all her heart, are hideously expensive and only available to nobility, she has to use her knowledge from her former life to work toward a future where she can create books on her own.
Yes, it's slow-paced and certainly not for everyone, but it's smart, funny, different, and I find it interesting.
Anyway, I just now learned that it has an anime, which I didn't recognize because the commonly used title wasn't one I was familiar with--Ascendance of a Bookworm.
Not even sure I'm going to watch it, to be honest. It's kind of hard to imagine the slow and detailed pace being squeezed into an anime. Seems like it would either be accelerated too much or it would kind of drag in real-time form. Some works are easy to imagine as anime, others aren't.
