Reborn to Master the Blade is an adaptation of the Hobby Japan-published light novels written by Hayaken and illustrated by Nagu. The series began in November 2019 and has eight volumes as of August 2022. The light novels are published under the HJ Bunko label.

J Novel Club describes the plot as:

From his deathbed, Hero-King Inglis, the divine knight and master of all he surveys, gazes down on the empire he built with his mighty hand. Having devoted his life to statecraft and his subjects’ well-being, his one unfulfilled wish is to live again, for himself this time: a warrior’s life he’d devoted himself to before his rise to power. His patron goddess, Alistia, hears his plea and smiles upon him, flinging his soul into the far future. Goddesses work in mysterious ways—not only is Inglis now the daughter of a minor noble family, but at her first coming-of-age ceremony at 6, she’s found ineligible to begin her knighthood! However, for a lady of Inglis’s ambition, this is less a setback and more the challenge she was (re)born to overcome. “It’s not the blood that runs through your veins that makes a knight; it’s the blood you shed on the battlefield!” The curtain rises on the legend of an extraordinary lady squire reborn to master the blade!
