Sebek is loud, hot-blooded and prideful. Other students have experienced discomfort over the sheer volume of his voice. Despite being half-human himself, the back looks down on humans (Except you) and makes this very clear through frequent patronizing comments. At times though he can act sweet (almost like a tsundere.) Sebek is also very serious and focused, he is also very passionate, and will fly into rage if he perceives someone is not treating you with what he deems to be proper respect.
