Though I suppose I should have mentioned the others by their full names...
Izumi-san must be your 'Secchan'. His full name is Sena Izumi. However, most people know him here by 'Veles'. That is the name his unit gave to him.
[ He only uses that when talking about him to people unfamiliar with his real name.]
King's full name is Tsukinaga Leo. But he goes by a million names here so it is difficult to keep up with them all. People tend to refer to him as 'Shishiou' or 'Hoshi' in general. However, he unreasonably demands that I call him 'King' and was upset when I once called him 'Ou-sama'. So I'm not sure why he demanded I refer to him differently.
