Mahou Shoujo Ore

Saki Uno struggles to succeed as an idol alongside her friend Sakuyo while secretly admiring Sakuyo's brother Mohiro, a much more successful performer. When demons threaten him, Saki accepts an unusual offer of magical power so she can come to his rescue.

The transformation is not what she imagined: she becomes a muscular male fighter dressed in a magical-girl costume. Defending Mohiro, keeping her identity hidden, and continuing her idol career become inseparable challenges, as affection and friendship complicate a heroic role that refuses to follow familiar expectations.
