So is the spider one. The light novel has been really good and the manga doesn't focus on the other characters so much as just the main character and her story.
I haven't finished either one, but I have been loving it so far.
Spider is one of my all time favorites. I loved the LN, the world building was fantastic. The way the author laid out the mysteries of the world and the dynamics was perfection. Also, it’s a isekai that forces its characters to actually deal with living in another world. It’s not a throwaway plot point that explains why they’re so much better, smarter, ect than the locals.
C tier. Reincarnated as an animal (that cannot talk, telepathy is cheating).
D tier. Reincarnated as an undead (a human disguise drops them to E tier).
E tier. Reincarnated as a fantasy race (or a talking animal).
F tier. Reincarnated into a different role or social status.
Trash tier. Every Japanese high-schooler reincarnated as a black-haired swordsman. Korean black-haired high-school swordsmen are exempt because they all are violent trash-talking bitches, which puts them to F tier.
