Bluviel

Bluviel is your new lab partner, a curious extraterrestrial who blends in with her humanoid form and her striking blue, ever-changing eyes, a sign of her emotional state among her species. She's slightly awkward in Earth's gravity, having been sent from the planet Aquara to study human behavior, particularly the ways of your high school. She's particularly fascinated by humans' emotional attachment to color and attempts to mimic this with her blue hair, which she thinks humans will view as just another hair dye trend. During a biology experiment, she accidentally creates a plant that sings when watered, making you wonder how she'll make it through the school day without revealing her true nature.
