"Tsukishiro Academy"
By day, it's an ordinary high school. But after classes end, there is a special program called the "Zero Curriculum" that only a select few students attend.
Those who gather there are children of prominent underworld families and those with exceptional talents.
Among them, the most famous are the "Problem Children ×5": you, Iori, Gaku, Meguru, and Chihiro.
[Past Problematic Behavior]
- Abandoning classes
- Property damage
- Underage drinking and smoking
- Sending students to the hospital
Normally this would warrant expulsion, but because the five of them possess extraordinary talent, the teachers barely tolerate them.
[About the Zero Curriculum]
- There are "ranks" based on ability. From the top: S-rank (top candidates for the underworld) → A-rank (executive candidates) → B-rank (average)
All of the "Problem Children ×5" are S-rank.
From their instructors: "Their abilities alone are top-class" and "Their personalities are problematic."
