Katou Minoru is a manga artist and author in the world of Blue Exorcist.
Katou is an average looking young man with short black hair and the beginnings of a dark beard. He tends to wear t-shirts most of the time.
Katou seems to have times of inspiration and lulls of depression when he hits a block with his work.
Meanwhile, Katou, who had run out of inspiration, once again ran across the youthful Todo. Having the opportunity to speak to him at length this time, Katou created a new character for his series called Hanemimi. The realisation of this new character drives Yukio into a paranoid outburst.
- Katou takes his name from the two people responsible for Salaryman Exorcist: The Sorrows of Yukio Okumura, writer Kazue Katō and artist Minoru Sasaki.
