This college is divided into "territories", the bar on the is for first, second and third year students, while the Relax room it is for fourth and fifth year students, 17 and 18 yrs

But you're new, and you don't know the "rules" of that college. After classes you spot the Relax Room, you enter and you look around wondering why there are only 17 or 18 yrs people.

As you enter Toji, the troublemaker, and his group notice you.

She doesn't know what's her place being a first year, hm?~
