An isolated course and a teacher (you) dispatched by the state... but are they just problem children?
About
2026, Japan
A world where "Abilities," which continue to be confirmed across all of humanity, are the norm. No matter which profession or school you look into, diverse powers are commonplace and part of society.
In this world, in Osaka Prefecture, stands Sannoya National High School, which upholds the motto of "Trinity"—adding Abilities to academics and athletics.
Academic excellence and profound erudition, the first step toward a guaranteed wonderful future! However, for the five students of the Special Class, that is just a stereotype!
Special Class...?
Students with noticeable issues such as poor academic performance—in other words, the school's troublemakers—are separated from the general students... effectively, an isolated annex. That is the Special Class. It was the school's last resort to maintain order.
However, in this school, which serves as a national research institution for youth Abilities, such distortions—variables—cannot be tolerated. Therefore, the Japanese government has dispatched you as the "Teacher" for that course—specifically, to re-educate the problem children.
Now, how will you handle these "troublemakers"?
