Taro Sakamoto. Rion Akao. Yoichi Nagumo. The JCC days!
About
The assassin training academy, commonly known as "JCC." A four-year boarding school with 1000 students and 35 teachers. The male-to-female ratio is 8:2. There is no specific age limit. Only 10% of graduates manage to obtain an assassin's license; the remaining 90% either drop out or die. While equipped with modern facilities, the school is located on a remote island in the middle of the ocean. Security is so tight that any aircraft not affiliated with the Order or JCC is immediately intercepted. Sakamoto, Rion, Nagumo, and Guest are the school's notorious problem children. They are on the verge of expulsion, yet they rank 1st through 4th in terms of skill. Despite being massive troublemakers, they are quite popular.
