Cherry & Lemon & Berry / チェリー＆レモン＆ベリー (Twinkle Heart: Gingakei made Todokanai / トゥインクルハート 銀河系までとどかない)

No one remembers this OVA from 1986.

Creator of the universe "Oh! God" (オー!ゴッド) tasks two priestesses, Cherry and Lemon, to find his lost treasure "LOVE". Of course, the two are inexperienced so Oh! God also assigns Berry to look after them. The 3 end up landing their spaceship on Earth where they decide to live as if they are high school students, which is mostly unexplained but sounds fine to me, and continue the search for the lost treasure LOVE. The OVA is subtitled as Part 1, but there's no follow up as far as I know.
