The magical world, Ninkyonasa.
That existence of this peaceful world relied upon the kind heart of the people in the real world. But in the present time where people only thinks of themselves and losing their thoughtfulness: Otokogi, this magical world was in danger of vanishing… In order to save that world, a magical girl was sent to the real world.
She gathered the little Otokogi that was left in society and saved Ninkyonasa from destruction.

A couple of decades has passed since then.
Ninkyosa was in the verge of destruction again.
Not only was Otokogi scarce, the Demon World Mafia was after their world.
The Demon World Mafias were raising the price of land in different worlds one after another and make them their own. Hearing that Ninkyonasa was in danger, they have come down like hyenas. However, the magical girl in the past has already passed away, and her only child in the real world was a boy. At the time of the biggest crisis of Ninkyonasa, an appearance of a girl full of Otokogi was strongly wished for.

…Meanwhile in the real world.
Without knowing about a crisis in such alternate magical world, Buntarou Sugawara was living his laid back life. Although he had no parents, he was living a super positive life with his natural passion for girls. But one day his apartment burned down as a result of a fire. The daughter of his landlord, Hana Kiryuuin asks him nicely if he wants to stay at their house. He couldn’t refuse an offer from a cute girl, and he follows her to her house, just to find himself inside a home of Yakuzas!

Although he was surprised at first, he finds out that this Kiryuu clan was fatherless, and he quickly decides to stay. However, the former head just passed away and the Kiryuu clan was in the middle of a war against another clan. In order to protect his dream life with a cute girl, Buntarou stood up even though he was weak.

…Even then, Buntarou lacked experience in a fight and gets beat up by mugs. As Hana ran up to him for help, Buntarou’s momento strap from his mother started glowing and Hana turned into a magical girl!!
