If you want some action people who are the reincarnations of various historical figures (Returners and E-Gene Holders) who serve an organization (Forest of the Greats and DOGOO) while combatting a bunch of baddies (Sinners and Evolutionary Invaders), along with some vibrant-looking visuals, then check these 2 series out.

PS: There are some differences, like the roles of the protagonist and deuteragonist have swapped genders, and the protagonists' personalities are different (a smart but untalented boy, and a clumsy young girl who likes militaria).
