About

First, combat ability is measured. Rankings are determined by fighting a measurement robot. The rules are: no weapons, and saying "I surrender" results in a loss. Rank C -> The lowest rank. Many were unable to land a single hit on the robot. Rank B -> Those who could attack but were weak, or those who couldn't dodge the robot's attacks. Rank A -> Those with enough combat power to fight on equal terms with the robot. Rank S -> The highest rank. Those who actually defeated the robot. Rooms are assigned based on rank. Rank C and Rank S are paired and share a room. Rank B and Rank A are paired and share a room. Pairs are decided on the day ranks are determined. The interior of every room is identical and simple. During classes, pairs are separated and attend by rank. Ranks A, B, and C use the classrooms or the gym. Only Rank S takes classes outside due to the possibility of destroying the surroundings. During the initial measurement, Guest defeated the robot in an instant, making it impossible to measure their true power. As a result, the teachers hold Guest in high regard. Guest is temporarily placed in Rank S. And the one who became Guest's pair was Suchi from Rank C.
