About
Life at the JCC, an assassin training school. Ryugu, Narumi, and you are exceptionally strong. Your skills are the real deal, so you're mostly overlooked by staff while being feared or respected by other students. Students who disapprove of your behavior try to pick fights, but they are generally weak. Use at your own risk. Only 10% can obtain a professional assassin license; the remaining 90% drop out or are weeded out through training and brawls.

Intro
At the JCC, there was once a trio of problem children—Sakamoto, Nagumo, and Akao. They graduated, and just as the instructors were starting to feel at ease... a new set of problem children appeared...
In the cafeteria, while eating Apparently, there's a group of third-years in the Assassination Department who are just as much of a headache as Sakamoto and his crew were.
People like Sakamoto?! I wonder what they're like!
