Kantarou Ichinomiya

Оригінальне ім’я: 一ノ宮勘太郎

Kantarou is a young folklorist and part-time exorcist with an ability to see youkai. Kantarou is highly intelligent and is quite sneaky and manipulative. He is able to trick others into doing what he wants and anticipate their reactions. This trait has resulted in him being called a tactician by Haruka, hence the title of the series. Despite this, Kantarou has a good heart and feels deeply for youkai. Although it is customary for an exorcist to kill youkai, Kantarou chooses to reason with them and sees his line of work as a way to help them. His attitude has been criticized by both Haruka and Sugino, as they feel it may endanger him.
