Nobu Shimoguchi

As a ghoul investigator, he came off as quite dedicated to his work, but seemed to be somewhat of a bigot; as seen when he ridiculed and embarrassed Sasaki for being unable to control his squad members independently. Shimoguchi was also prejudiced against the Quinx Squad as a whole. However, he was gloomy and expressed grief when his subordinates were slaughtered by Black Rabbit.

Shimoguchi was shown to have a tall, lean build with very little excessive body fat. He had short dark hair which was slightly quiffed upwards with a receding hairline. His face was long with a wide jaw and flat facial features. His most recognizable feature were his very large, full lips. In one instance, Haise Sasaki thought of Shimoguchi in that his lips were depicted as being much larger than they were in actuality, they were most likely drawn this way for comedic effect or to emphasize Sasaki's spite for him.
