A 3rd year! Someone who sits right between lethargy and normalcy. Occasionally mischievous, he is the oldest among the 7. He's so good at studying that ranking 1st or 2nd in the whole school is routine. His hobby is coding, and he used to be in the Mechanics Club, but is currently active in the Broadcasting Club!

A 3rd year! She has a bright and kind personality, but to the 7... she's a scary person steeped in madness. As the Student Council President, she excels at her studies with Grade 1s in most subjects. She is the head of the Broadcasting Club!

A 2nd year! A former member of the Sports Club with a bright and cheerful personality who is good at sports. Currently a member of the Broadcasting Club and one of the loudest among the 7! He visits the board so often he's practically a regular, and has a relatively gentle personality!

The loudest of them all, he's the resident troublemaker of the 7. He seems to do nothing but play, but they say he studies intensely at dawn when no one is watching... and his grades are actually quite good! He was in the Board Game Club but joined the Broadcasting Club as he moved up a grade!

A rabbit-like person who is truly the loudest... in terms of volume. His nickname is Princess Cleopatra. Every day, he brings the newly enrolled Deokgae to his class for a 'Cleopatra Game' showdown... and occasionally his 'psycho' instincts kick in!

A freshman who just enrolled. A loud person who goes to Soohyun's class every day for Cleopatra showdowns! On his first day, the older members pulled so many surprise pranks on him that he was shy enough to hide his face in class... but now he's sometimes prickly toward the 7, and above all, he's a huge coward!
