Taiju is a deeply brutal, sadistic individual, regularly resorting to violence at the slightest provocation and with a cruel disposition towards nearly everyone, particularly his foes who end up in the receiving end of his brutality. Even then, he was known to be a devoted Christian, praying every year on Christmas.He sports a crazed grin and exhibits all sorts of unusual expressions - one eye opening wider than the other and his forehead vein popping out - when fighting or when excited.
