Fics like Multiverse-Crafter

A normal guy from our world reincarnates as Jaune Arc before RWBY’s first season, awakening a Creation Semblance that lets him creat powerful tech and magical items using Dust or Aura. Determined to create a better world for humans and faunus, his inventions [drawn from games, anime, comics, and more] start turning Remnant upside down. But what he didn’t expect? Some female members of the original cast quietly forming a harem behind his back. Due to popular demand, this story is a harem, RWBY P, to be precise.
