Professor Gojyou Shiouji is a character in the anime and manga series Excel Saga and was created by Koshi Rikdo.
Professor Shiouji is something of a 'pretty boy', almost a bishounen. He has short purplish hair and eyes and wears glasses. In all his appearances he wears a suit and tie under a white laboratory coat. His behavior and demeanour is somewhat eccentric, tending towards displays of high class and nobility.
Described by many — including himself — as a genius, Shiouji holds doctorates in a wide range of subjects, including engineering and computing, although he admits he has no training in medicine. He prefers the finer things in life and tries to do everything with a touch of elegance and class, and can be something of a showman at times. He has distinct mother issues, which have tainted his attraction to women — he despises any woman with a cleavage like his mother's — although he has made semi-romantic overtones towards Misaki Matsuya at least twice.
Shiouji has never tried to hide his love of loli and will stop everything he's doing, including a conversation, to look at a girl that catches his eye. He is quite obvious in his approach, especially in the anime, in which he has been known to follow a girl on his hands and knees just to keep looking at her. He sometimes appears in the anime with a young girl acting as his assistant and on one occasion as his driver. He is very friendly and personable with his girls.
