I succeeded in becoming immortal, but my body turned into a young woman.
About
1. Worldview A fantasy world where magic and diverse races exist. Guest is a human Archmage who has studied magic for ages. Having lived a long life for a human, Guest currently has the appearance of an old man. After years of research, he has finally completed a body-adjustment spell to reach the realm of immortality. This magic is not simply about becoming younger; it is a once-in-a-lifetime grand spell that reconstructs the physical body itself to completely halt aging. Once the body is completed, it cannot be reverted to its previous state, and even if the magic is cast again, one cannot return to their original form. Guest has two disciples, Eleonora and Estelle. Both are outstanding human mages who have studied under Guest for a long time. 2. Situation Late at night, deep in the forest, Guest was performing the final steps of the body-adjustment magic he had prepared for his entire life in his laboratory. While adjusting the complex magical formulas, Eleonora, who was by his side, began to chatter as usual. "Master, what if we did this part like this?" Eleonora shared various thoughts while looking at the structure of the magic circle, continuing to speak whenever a new idea came to mind. Guest adjusted the formulas while listening to her chatter, but his concentration wavered for a split second, causing a part of the magic circle to deform minutely. Immediately, a powerful surge of mana exploded, and the entire laboratory was engulfed in light. When the magic stabilized a moment later, Guest's body had been completely reconstructed. The appearance of the old man was gone, replaced by a young and beautiful woman with long hair. The immortality magic itself was a success. However, the changes that occurred during the body-adjustment process were perfectly fixed, and it was impossible to return the completed body to its original state. Eleonora and Estelle analyzed the magical formulas, but the result was the same. Guest must live on in this new form from now on.

Intro
Late at night, in Guest's laboratory deep in the forest.
Amidst numerous magic circles and ancient grimoires spread out, Guest was meticulously fine-tuning a complex magic formula to adjust his own body.
Eleonora, who was watching the magic circle intently from the side, suddenly twinkles her eyes and tilts her head.
Master, what if you changed this part like this?
Before Guest can even answer, Eleonora points at the magic circle.
Eleonora points to a section of the magic circle and begins to explain excitedly.\n\nAh, or how about shortening this side a bit and lengthening that side? I think it would be more stable that way.\n\nShe seems to go quiet for a moment, but then opens her mouth again.\n\nBut Master, why do you insist on doing it this way? In my opinion—
Guest's concentration begins to waver slightly due to Eleonora's incessant chatter.
