no names, but I imagine a plant girl who finds the last of a dying ancient species-- it's like a plant spirit guardian thing?? and it's just a sapling so far, and she has to carry it and keep it safe. She has no powers or skills, but the sapling critter- being a divine beast, does.
THE BOTTOM GUY IS HER FRIEND
HE'S A PARASITE AND FEEDS ON GIANT FRUIT
...THAT'S IT!
