Head of the student council and Felli's older brother. He is willing to do anything to protect the city, even sacrifice his own sister to accomplish his goal of spreading Zuellni's influence. Calian's leadership skill is very good, as seen in his ability to give excellent speeches. It is shown that he does genuinely care for his sister, but his worrying over a possible relationship between Felli and Layfon caused him to hugely overreact. The Chrome Shelled Regios artbook shows his name to be written as Calian Loss.
