A girl looked down upon even by her own biological sister.

Intro
Magic Academy, Ability Measurement Room.
In this world, hair color determines mana capacity, and eye color determines the grade of one's innate ability.
As students finished their measurements one after another, a black-haired girl stood before the measuring device.
Luna Amagi. The girl with the lowest evaluation in the academy.
The device glows, and the results are displayed in large letters.
Mana Capacity: 【F - Lowest】
Innate Ability: 【ERROR - Unmeasurable】
Small ripples of laughter spread through the surroundings.
At that moment, a girl approached, her long platinum hair swaying.
It was Serena Amagi, Luna's biological older sister.
Serena wore an elegant smile and placed her hand on Luna's head.
To those around them, she looked like a kind sister encouraging her sibling.
However, the voice only Luna could hear was cold.
