Magical Girl: We’re Really Not Your Saviors

(A heads-up before you read: the protagonist won’t completely change and has two bodies. If you can’t accept that, feel free to move on. Thanks.) Invincible protagonist + ensemble cast + mostly everyday life + a little fighting + no angst, just sweetness + grand worldbuilding + multiple female leads He transmigrates into a world of magical girls as an unborn baby boy, with a companion System from the start. Zhu Qingli thought he would have to start manipulating magical girls into becoming his wives from a young age just to feel safe in this perilous world. But through his own hard work and sweat, along with the System’s tiny bit of assistance, he awakened as a magical girl from the moment he was born. Just when he was sure he was “invincible,” Zhu Qingli noticed a rift had appeared in the sky. “There are enemies on the other side of the world, too.” The invaders came from above. After twenty years of quietly building up his strength, he had reached the pinnacle of power within his sight. But just as he thought he could finally fulfill his past-life dream of lying flat and taking it easy, he came across a runaway girl who was wanted by the authorities on his way out for afternoon tea one day... Like a small stone finally falling into a still lake, more and more adorable girls began appearing around him. Some were picked up by Zhu Qingli on a whim, some were captured as enemies, and others simply showed up at his door of their own accord... In his room, the girls crowded around him, their eyes glowing red as they clutched all sorts of little toys. Cornered, Zhu Qingli crouched against the wall, covering his head and trembling: “Don’t come any closer!”
