Miya Kazuki’s Daughter of a Soldier, Volume 2 is the second of three Daughter of a Soldier instalments, which in turn form the first arc of Miya Kazuki’s Ascendance of a Bookworm series. The manga was illustrated by You Shiina; the 2019 edition was translated into English by Quof.
Fanatical bookworm Urano Motosu eluded the homicidal embrace of Truck-Kun, only to be crushed by her own books during a minor earthquake. To her surprise, Urano woke in the body of five-year-old Myne, a sickly child born to an honest but very poor peasant family. Her new society is sufficiently pre-literate that the language in which Urano is now fluent (as Myne) does not have a word for book.
Urano has been working as hard as her frail body will allow to drag society into literacy. This has born fruit, although not quite the fruit she intended.
