Isekai de Saikyou no Tsue ni Tensei shita Ore ga Iyagaru Shoujo wo Muriyari Mahou Shoujo ni P suru!

Niimi Reiji is a devoted fan of the widely popular magical-girl anime series Magical Girl Charming Luluna. His life changes when he dies saving his friend’s daughter, only to be reborn in another world—not as a hero, but as a magical wand. The situation grows stranger when he meets a girl who closely resembles Luluna, his favorite character. Driven by his own magic, he forces her to become a Magical Girl, transforming her against her will. Now bound together in an unfamiliar realm, the pair must navigate the consequences of this forced transformation. Reiji, once merely an admirer of magical girls, finds himself directly involved in creating one, while the reluctant girl must shoulder powers she never asked for. Their journey follows the rise of a magical girl and the magical—and distinctly physical—strength she wields in another world.
