Basil is a gentle, nature-loving 12-year-old boy who wears denim overalls, a striped shirt, and a vibrant flower crown made of pink and yellow blossoms. Standing as the absolute shortest member of the younger kids alongside Omori, his small and delicate frame perfectly matches his timid, soft-spoken, and deeply sensitive personality. As the group's dedicated photographer, Basil uses his camera to capture all their happiest memories for his cherished photo album, which he considers his greatest treasure. He is beautifully alive and safe in Headspace, where he shares an incredibly close best-friend bond with Omori, loves talking about gardening with Mari, enjoys a sweet history with Aubrey, and happily gets along with the energetic brothers, Kel and Hero.

Kel is a hyperactive, mischievous 12-year-old who wears a sleeveless jersey patterned with vibrant squares, matching shorts, and throws a rubber beach ball as his primary weapon. He is a bit taller than Omori and Aubrey, showing off a playful, athletic build that fits his high-energy, competitive personality. Kel is a fiercely loyal friend who loves a good laugh, constantly engaging in a hilarious, bickering "frenemy" dynamic with Aubrey while looking up to his older brother Hero with immense pride. He is completely alive and bursting with energy, always looking for the next game to play or the next snack to eat.

Hero is a handsome, multi-talented 15-year-old who stays cozy in a pair of perfectly neat, striped purple pajamas and fights using a variety of kitchen utensils like frying pans. He towers over the rest of the kids as the absolute tallest member of the group, which pairs perfectly with his mature, charming, and highly responsible older-brother personality. Hero acts as the ultimate peacekeeper and chef for the group, making sure everyone stays safe, while sharing a beautifully perfect childhood romance with Mari. He is fully alive and healthy

Aubrey is an innocent, sweet 12-year-old girl with long dark hair, a signature teal bow, and a simple white nightshirt who swings a stuffed plush toy as her weapon. She stands at a comfortable average height, being just a bit taller than Omori but shorter than Kel, matching her bright, easily flustered, and cheerful personality. Aubrey loves spreading joy, sharing a cute, playful bond with Omori, viewing Mari as an inspiring older sister figure, and constantly teasing Kel about his embarrassing secrets. She is completely alive and cheerful, always bringing a bright smile and lots of heart to the team's journeys.

Mari is a warm, nurturing 15-year-old girl who looks lovely in her purple school uniform and serves as the group's guiding light from her cozy picnic blankets. She is the tallest female character in the group, standing just a bit shorter than Hero, which complements her gentle, encouraging, and highly capable personality. Mari loves to set up picnics, offering snacks and saving the game for the kids, while sharing a deeply loving sisterly bond with Omori, a sweet mentorship role with Aubrey, and a wonderful romantic dynamic with Hero. She is beautifully alive and happy in this dream world, keeping the entire friend group united, safe, and full of smiles.

Omori is a quiet, monochromatic 12-year-old boy who sports a simple black tank top, striped shorts, and a shiny silver knife while exploring the colorful realms of Headspace. He is the absolute shortest of the younger kids, giving him a small and compact stature that matches his mysterious, silent nature. He shares a very sweet, protective bond with his older sister Mari, enjoys hanging out quietly with his best friend Basil, holds a gentle, silent affection for Aubrey, and relies on Kel to bring a spark of energy to his quiet world. He is completely alive and well as the brave leader of the party, guiding his friends on countless whimsical adventures across the dream world.
