The Strongest Magical Girl My Little Sister Admires Is Actually Me

It's been a full year since Mahiru quit being a magical girl.

After all, it was pretty bizarre for a boy like him to become the strongest magical girl, called Yukina.

Thankfully, he no longer had to worry about magical girl business. He could devote himself wholeheartedly to taking care of his incredibly adorable little sister, Shinoya.

Going to and from school together with such an adorable little sister every day, sharing an ordinary yet happy life, was such a joy.

But he never imagined that his excessively cute little sister actually worshipped Yukina, the strongest magical girl. She had even joined the Magical Girl Association and become a magical girl herself, fighting in battle.

If she found out that the strongest magical girl she worshipped, Yukina, was actually her older brother, their precious sibling bond might turn strange on the spot.

"Hey, Nanan-chan, you wouldn't want her to find out that you're her older brother, would you?"

Threatened by his former master, Mahiru had no choice but to return once again as Yukina, the strongest magical girl.
