Angelium(2004)

Angelium is an anime series that follows three young angels—Yuu, Miki, and Chadoko—who descend to Earth to take a promotion exam held once every three years. While working part-time at a flower shop, they face a series of unexpected trials. Unknown to them, Zeus watches from Heaven, ostensibly to aid their progress, though his true motives are far from noble. His secret interference doesn't go unnoticed in the mortal realm, setting off a chain of complications. The series blends comedy with mythology as the angels navigate their earthly challenges while Zeus's scheming threatens to unravel.
