Sorry for begun out of the topic but :

Is Taiyou an 1st year or 2nd Year or 3rd Year ?

If he an 1st year, why in chrono stone called Nishiki,Kirino,Shindou (-san) instead of (-senpai) ?

If he an 2nd year like Nishiki,Kirino and Shindou, why he call them (-san) even he is in the same age as them!

if he a 3rd year, why he would say to who smaller than him in age (-san) ?
