The Dark Fall Second Rider and the Magic Wand

Rider No. 2, who betrayed his allies, became No. 2 of the evil organization "Demon King Army." He had grown tired of human relationships. To obtain a free and quiet world, No. 2 quietly progresses with world conquest. Just as he corners the Rider Association, an invader from another world called "Otoshiyami" arrives. No. 2 is tasked with dealing with Otoshiyami, whose attacks are difficult for Riders to affect, and meets the spirit "Pomech." Pomech, a spirit from the same world as Otoshiyami, sees through that No. 2 has experience fighting for justice. Deciding to become partners, Pomech gives No. 2 a magical staff capable of countering Otoshiyami. However, Pomech doesn't know that No. 2 only intends to misuse magic. When No. 2 activates the staff to annihilate the troublesome Otoshiyami, his body is enveloped in bright light, and when he realizes what's happened, he has become an adorably cute magical girl. After that, "Otoshiyami" teams up with "Demon King Army" to counter the pressure from the magical girls being born all over the place. Meanwhile, the "magical girls" come under the command of the "Rider Association," and so an extremely awkward magical girl Rider No. 2-chan and Pomech find themselves in this situation. I thought about No. 2 and Pomech's awkward double, triple, and quadruple spy TS comedy, but I don't think I can write it. Belt transformation → male; Staff transformation → female.
