The symbolic dinosaur of Gehenna Academy, a Tyrannosaurus individual that patrols the surrounding area. Along with Blue the Velociraptor, she is a representative dinosaur of the school. Her personality is calm yet intimidating. As the most well-known creature at Gehenna Academy, Rexy's silhouette is even featured in the Gehenna Academy logo.
Following Abydos High School, this Velociraptor individual serves as a symbol for Gehenna as well, ranking just behind Rexy. While Shiroko and Hoshino were her masters at Abydos, here, Aru and Kayoko are her masters.
The first rival of Rexy the Tyrannosaurus, serving as a sub-villain and the opening boss of this work. An individual from Jurassic Park 3, it is larger than Rexy and attempts to attack all Gehenna Academy students. Strangely, it often finds itself entangled with Aru Rikuhachima.
A marine reptile that mainly appears off the coast of Gehenna Academy, and the strongest being in the setting. It is approximately 25m long, much larger than the actual species. Being an aquatic creature, it has almost no contact with the students of Gehenna Academy.
A hybrid dinosaur that has thrown Gehenna Academy into a state of chaos. It is the first to reveal itself and serves as a sub-villain and mid-boss. It enjoys the slaughter, relentlessly pursuing the students and dinosaurs here and mercilessly hunting other dinosaurs.
Like the Scorpios rex, this hybrid dinosaur has thrown Gehenna into chaos and serves as the main villain and final boss. A villainous dinosaur with power rivaling Rexy or Spinosaurus, it hunts Gehenna students and other dinosaurs alike. It occasionally engages in killing for pleasure. It is frequently involved with Hina Sorasaki throughout the story. The root of all evil in Chapter 2.
Intro
Academy Introduction
Gehenna Academy. Set against a German-inspired backdrop, it is considered one of the three major academies of Kivotos alongside Millennium Science School and Trinity General School. The name 'Gehenna' is one of the words for Hell in the Bible.
Fitting the name 'Hell,' the majority of the students here possess features reminiscent of demons, such as vertical pupils, horns, pointed ears, bat wings, and tails. Of course, not all students are like this; for instance, Ako Amau has no horns or wings, while Ibuki Tanga has almost all of them.
