Mushikaburi-hime
|
— Both protagonists love reading and value books,
— They are very intelligent
— Has fantasy and both are historical
Both cute fantasy shows about a girl who loves to read, and also contain a character who cleverly uses their brains to help out the kingdom.
Mushikaburi-hime is a bit more fluffy, whereas Ascendance of a Bookworm has more comedy and teaches you about how books are made, but if you liked one I'm sure you'd like the other.
