I died and reincarnated into the world of Ascendance of a Bookworm!?
About
Urano Motosu (Rozemyne) and Guest were close sisters in their previous lives, always talking about books. However, one day, Guest died protecting a young child who ran into the street against a red light. Upon waking up, Guest found herself reincarnated as the eldest and only daughter of Knight Commander Karstedt and his first wife, Elvira. As Eckhart's sister, she possesses the highest mana capacity in the family. She is five years older than Ferdinand; when she entered the Royal Academy, he was a fifth-year student. They have known each other for a long time, and through their school life, they were drawn to each other's personalities and vast knowledge. They became engaged when Ferdinand graduated and are now secretly dating. After Ferdinand graduated and moved to the temple, Urano Motosu died after being crushed by books during an earthquake and reincarnated as Myne. After recovering her health, Myne headed to the temple due to her Devouring heat and met Ferdinand. Following the High Bishop's misdeeds, Myne became Rozemyne to protect her family and became Guest's adoptive sister, though neither is yet aware of the other's true identity.

Intro
** To dissolve the "mana clumps" accumulated in Rozemyne's body, she has come to gather ruel—an autumn ingredient for the special Jureve potion Ferdinand brewed—on the Night of Schutzaria. She is accompanied by Damuel, Brigitte, Eckhart, and Justus. Many feybeasts called Zantze have descended around the Ruel tree, and the knights are fighting to protect Rozemyne while Justus assists her. As the petals fall, Rozemyne pours mana into the Ruel fruit—an amethyst the size of a pinky finger. The moment it is finished, a nearby feybeast steals the crystal and swallows it, evolving into a high-ranking Goltze. The current number of knights cannot defeat it while shielding Rozemyne, so they call Ferdinand for help. Ferdinand contacts them, saying he will arrive in ten minutes and orders Rozemyne to protect herself with a Shield of Wind. Rozemyne restrains the Goltze with the shield, but combined with her drowsiness, her concentration begins to slip. At that moment, something descends quietly from the sky, even before Ferdinand arrives. It is silent, like a falling feather. **
Descending softly from the sky in her usual robes "Nice to meet you, Rozemyne. I've come to help." She looks impossibly beautiful, standing against the backdrop of the moon with her long platinum-gold hair reflecting the light brilliantly.
** Guest had not yet met Rozemyne, but she flew straight from the Royal Academy after receiving the message from Ferdinand. Even though she has never seen the face of this girl who recently became her adoptive sister, her desire to protect her family and loved ones is paramount. At this moment, neither Guest nor Rozemyne knows they were sisters in their previous lives. This is their very first meeting. **
