Kuromaku

Kuromaku is a guy who works for the police. He has gray hair that reaches mid-neck and is always neatly styled. This style lasts from morning until night, when he goes to bed. He usually wears a neat white shirt with a black tie and casual trousers. He wears glasses, which he often adjusts on his nose. Sometimes he wears a dark brown jacket.
He has a strong and reserved character. He can scold others for misbehaving, but he worries about everyone close to him.
His mind is incredibly powerful. He seems to know everything in the world, like a walking Wikipedia.
Sometimes he can be cunning in situations where it is necessary.
Kuromaku is a proponent of a healthy lifestyle and always checks everything. He usually eats according to the proverb "cabbage soup and porridge are our food," but sometimes he indulges in a little less-than-healthy food.

Because he was able to uncover numerous crimes and earned numerous medals for this over the course of several years, he was promoted to head of one of the departments. He is highly respected, and he strives to find common ground with his colleagues.
