Gender Swap: I’m a Manly Man, So Why Am I a Magical Girl?!

[The world is gentle] "So?" Chen Daolin listened to its explanation, weighing in his mind how he would track down this thing's true form later. [So power manifests in the form of magical girls.] "Damn it!" A world on the verge of collapse. Fearsome invaders from beyond. The dark source born alongside the world. A girl surrounded by a yuri harem of magical girls, destined to lead them all in saving the world. Chen Daolin could never have imagined what magnificent waves an outsider like him would stir up. Even less could he have imagined that just flirting with a girl would get him chased down and beaten by a whole bunch of magical girls. (LOL)
