(translated from the Japanese version by daeva-agas)
Trein has the appearance of tall elderly man with small grey eyes and greying, neatly combed-back hair. He wears a standard black suit beneath long maroon robes. Attached to his collar is a white jabot, which is tied off with a turquoise-colored pendant. He comes off very stern-looking and unapproachable.
Trein's cat Lucius is a chubby, black long-hair with a white muzzle and golden eyes. He has white patches of fur at his chest and at the tip of his tail.
Trein was said by the students of Night Raven College to be a very strict teacher as shown when he warned his students whenever they fell asleep during his class or when he warned Ruggie for his poor grades. He is shown to have a great passion for history and wanted his students to respect and not to take the subject lightly and encourage them to study harder for the exams. However, it is evidently shown that he did care about his students a lot when he and the other staff members of NRC decided to cancel the Halloween party to keep them safe from the Magicam Monsters or when he worried about the school students which got dragged to the world ghosts.
He is shown to be very attached to his cat, Lucius, and has been described as a 'doting cat dad.' Wherever he goes, Trein always brings Lucius with him, and he becomes very panicked if he and Lucius are unexpectedly separated. If separated, Trein shows immense gratitude to whomever reunites them, as shown when he gives Ruggie Bucchi hints about exam questions after the latter returns Lucius to him.
Mozus is a widower and has adult daughters.
