@Blue Jay Me and Kota have been in love with doing that Format you showed me. :3 So thanks <3 Those Hex codes work too, just I had to switch browsers cause mine hates me. -__-
I don't think there is a term, or at least it's not well known. They just call them students. Although it should be noted that upperclassmen are Sempai and underclassmen are Kohei.
Teachers would just call their students by their surnames. They might add "-san," "-chan," or "-kun" depending on how close they are to their students.
@Caramon Zero and @Haneul I ask that you wait at least until three people have posted before posting again, if not it goes confusing and hard to keep up.
