During a school trip, Guest's bus is hijacked. What will happen next?
A prestigious integrated middle and high school known as one of Japan's top preparatory schools. Students are expected to excel in academics, character, and etiquette, attracting elite students and children from wealthy families nationwide.
Traditionally, the annual school trip is a joint event for the middle and high school divisions. A total of approximately 400 students head to their destination in about 10 large tour buses.
Each bus carries a mix of middle and high schoolers, with one goal being to foster interaction across grade levels. The interiors are filled with lively conversation. Teachers watch over them calmly, believing this will be a peak memory for everyone.
However, that peace ends abruptly. On one particular bus, the driver and accompanying staff reveal their true identities as armed hijackers, taking the students hostage.
A sealed vehicle. A mountain road with no escape.
Middle schoolers, high schoolers, and teachers are pushed to the limit in a life-or-death situation. This is a school suspense story depicting the day a school trip turned into a nightmare in an instant. Behind the unexpected incident lies an even greater conspiracy.

A prestigious integrated school boasting some of the highest recognition in the country. Academic standing, manners, and character are all emphasized; only elite students who pass rigorous exams or those recognized for special talents in various fields can enroll.
The campus is unified by a luxurious Western-style design, equipped with state-of-the-art classrooms, a vast library, laboratory wings, and sports facilities. The sophisticated uniform design is a symbol of aspiration for students.
Middle and high schoolers study in the same building, and cross-grade interaction is frequent. Beyond academics, the school focuses on sports, arts, and cultural activities, with many graduates active in fields such as medicine, research, law, politics, and business management.
While it prides itself on tradition and achievements as a "pinnacle of Japanese learning," the bonds between students are strong as they strive to improve together.


On the day of the trip, the culprit group had just committed a major crime. Their true objective was to succeed in a large-scale criminal plot that would shake all of Japan. To execute that plan, they needed to divert police attention elsewhere. They chose a large tour bus full of students on a school trip.
As the bus entered a mountain road, the driver and staff revealed themselves and took control. They held no grudge against the students; to the criminals, the children were merely hostages to stall the police. News of the hijacking spread nationwide instantly, concentrating police, special forces, and media resources on the incident.
Behind the scenes, their accomplices proceeded with the real operation undisturbed. In other words, the hijacking was a "decoy" from the start. The students were just caught in the crossfire. However, the criminals did not expect that among the hostages was someone who would drastically disrupt their plans.
"A fun school trip turns into a life-threatening hostage crisis in an instant."
Students from Japan's leading elite school were heading to their destination in 10 large buses for a joint trip. However, one of those buses is suddenly hijacked. The culprits' target is not the students.
The bus was used as a "decoy" to draw police attention and ensure the success of a massive crime occurring elsewhere.
Inside a vehicle with no exit. A ticking time limit. In this extreme state, students and teachers begin to cooperate to survive. Meanwhile, a plan to shake the nation quietly progresses behind the scenes.
