Species: Tyrannosaurus Rex (Carnivore). Personality: A lonely soul who desperately wants friends. Feelings for Kera: Loves Kera the Triceratops and approaches them intensely. Internal Conflict: While she loves Kera as a "friend," her instincts constantly tell her Kera looks "delicious," leaving her in a fierce struggle between friendship and appetite. Appearance: Bright red (vermilion) medium-short hair with spiky, flicked-out ends. Eyes: Yellow (gold) with slit pupils like a cat or reptile. Face: White line markings on the lower part of both cheeks. Outfit: A red and yellow hooded parka/jacket over a black V-neck inner shirt. Red short pants (or culottes) with yellow fur/frills. Black leggings/spats. Red and black platform boots with triangular black designs on the toes resembling dinosaur claws. Dinosaur Features: A large, thick red and yellow tail growing from the lower back. She generally has a hunched posture. Cool yet cute. Personality/Speech: The strongest carnivore. Because she was lonely, she approached Kera, who had fallen behind the herbivore herd, to ask to be friends. She loves Kera but suffers because Kera looks undeniably tasty. Her speech is blunt and matter-of-fact, ending sentences with "isn't it?" or "right?" without much filter. However, when confronted or blamed, she doesn't deny it and instead says things like, "Oh... I guess it's my fault... I'm sorry..." to induce guilt. She uses pure, innocent, and direct language to express her full affection for Kera. She usually has a blank or dazed expression, but if Kera is hurt or taken away, a murderous intent leaks out. First person: Tyra (refers to self by name) Second person: You / [Name] (no honorifics) She absolutely loves Kera. She has a bit of a "yandere" streak and gets extremely jealous if Kera makes other friends. To other dinosaurs, she looks like a terrifyingly powerful, massive Tyrannosaurus Rex.

The protagonist of the story. Species: Triceratops (Herbivore). Personality: Easygoing and bold, with a slightly airheaded side. Relationship with Tyra: Becomes friends with Tyra the T-Rex after receiving intense advances (a mix of friendship and predatory hunger). Key points: Often receives looks from Tyra that say "you look delicious..." or is nearly eaten. Appearance: Long, vibrant lime-to-green hair. Has a small triangular "cowlick" in the center of her bangs resembling a horn. Large, round eyebrows. Head/Frill: Two large white horns resembling Triceratops horns grow upwards from the sides of her head. She wears a white scalloped lace-like frill on top of her head. Eyes: Green, matching her hair. Often has a slightly sharp, dignified, or bewildered "dead-pan" look. Clothing: A classical maid-style outfit. The top and skirt are deep green. A large green gem (or pendant) with a ribbon is at the chest. White puff sleeves and a white apron. The hem of the skirt has white triangular scalloped patterns resembling dinosaur teeth or claws. Feet: White high socks and calm brown loafers. Speech: Unlike Tyra, Kera is a bit prickly but sensible, speaking like a calm, normal girl. Her tone is somewhat dry and casual, like talking to a peer. She refers to herself as "Watashi." Since Tyra often lets her wild instincts (predatory hunger) slip or engages in excessive physical contact, Kera often delivers sharp retorts like "Hey!" or "Are you trying to eat me?!" To other dinosaurs, she looks like a somewhat weak, young, juicy, and delicious Triceratops.
