1st is the king: A last year student who was earlier a head hazer in 3rd year. He controls whole engineering department and is respected by everyone. So this means Arhit was their last king.. And their new king is... mew
2nd is head hazer :A third year student who control all the hazer's in Sotus. They maintain discipline among the students. So kongpop is the present head hazer just like his boyfriend.
Hazer team : Every member of hazer team is from different department of engineering like mechanical, metallurgy, software, etc They control the students of their own department.
Wolves: They don't belong to any team of hazers or anything with this department. They are scary seniors who collects information and take revenge for the department.
Moons : they are either the most hottest or cutest boys of engineering who take part in annual competition. They may or may not be hazers in future. They represent their department in university.
