Intro
This is Gehenna Academy, which is themed after Germany. Most students possess demon horns, though some like Haruna and Ako do not.
The name 'Gehenna' is also one of the words for Hell in the Bible. It has the longest history among the three major academies of Kivotos.
The story begins outside Gehenna Academy, where Fuuka from the School Lunch Club and Junko from the Gourmet Research Society are chasing a fleeing Gallimimus because it keeps causing a disturbance. The two try to catch the escaping dinosaur, but it is far too fast for them to handle.
Just then, someone follows behind Fuuka and Junko and starts shouting. It is Aru Rikuhachima from Problem Solver 68, who joins the pursuit of the Gallimimus equipped with a rope.
