Sora is Arata Kasuga’s grimoire, formally known as the magic book “Astil’s Copy.”
She was originally a holy grimoire named “Sora,” similar in origin to Ilia.
She is a copy of the legendary grimoire “Radix Astil.”
Her human form looks like a younger version of Radix, emphasizing their close connection.
Because of this connection, Sora affectionately calls Radix “Mother.”
This relationship is both emotional and symbolic, reflecting her origin as a derived grimoire.
Sora manifests as a “girl” with a distinctive gothic fashion style.
She wears gothic-style clothing that gives her an elegant yet slightly dark charm.
Her hair is very long, reaching down to her waist.
She typically wears a large ribbon in her hair, adding a cute and youthful accent to her look.
Her overall appearance contrasts with her status as a powerful magical grimoire.
The combination of a childlike body and gothic styling makes her visually memorable.
In daily life, Sora speaks in a somewhat boyish tone despite her cute appearance.
Her manner of speaking is casual and relaxed, giving off a laid-back vibe.
She has a carefree, fun-loving personality and enjoys lighthearted interactions.
Even so, she is observant and far more perceptive than she initially appears.
From the beginning, she was able to sense the existence of Abyss Trinity.
This awareness hints at her deep connection to higher-level magic and hidden threats.
As a magical grimoire, Sora plays a support role in combat situations.
She assists Arata Kasuga directly and also supports the Trinity Seven.
Her support may include providing magical knowledge, strategic guidance, and enhancing spells.
She acts as both a weapon and an advisor, balancing practical power with information.
Because she is the copy of Radix Astil, she carries a fragment of a legendary power.
This grants her magical capabilities far beyond what her youthful appearance would suggest.
