In a realm where beings known as 'Majo' or 'Magical Girls' reside, blending in with society by concealing their mystical abilities, they coexist peacefully with humans across generations. Sasami, inherently gifted with magic since infancy, receives a solemn directive from her parents at a tender age to shroud her powers from the world. Adhering to this clandestine decree, she maintains a veil over her extraordinary gift. However, the arrival of a mysterious transfer teacher named Wajuu on the inaugural day of a new school term heralds a profound shift in Sasami's once ordinary existence.
