Keiichi Katsuragi is Keima's father. He is currently living in South America due to an unnamed business. He has never been physically seen in the manga. His existence is only confirmed when he is called by Mari about his "Illegitimate Daughters", Elsie and later Haqua.

Character Outline


It is unknown what Keiichi is like, as he has never been seen in the manga or anime. It is speculated that he has a calm and careful personality based on how he was somehow able to persuade Mari out of her biker gang life.


Although there has been no actual appearance of Keiichi yet, he was shown (without his face) during Tenri's Arc as a part of a flashback. Even so, that is supposedly an image of him 10 years ago so he may have changed in appearance over the years.


It is possible that Keiichi has good "capturing" skills since he was able to convince Mari to forsake her motorcycle gang and eventually married him. He also has a private study which possibly shows that he's pretty smart too.


He was able to stop Mari from the local biker gang and married with her, he seems to be very loyal to her but does not call her during his work in America. He has probably been located in New York after that Keima's dream is to go to New York.
