Set in Japan during the Taishō period, Tactics is the story of Kantarou Ichinomiya, a young man with the ability to see youkai and other mythical beasts. When he was a child, this ability resulted in him being ostracized by humans. His youkai friends told him that in order to be stronger, he must find the oni-eating tengu. The young Kantarou then vows to find it and name it. By naming one, a human becomes master and the name contract is only broken if the master chooses. As Kantarou grows up, he finds a career as a folklorist and a part-time exorcist, alongside his youkai friend Youko. An assignment leads Kantarou to a mountain where a shrine marks the place where the tengu had been sealed away. Calling upon the tengu by the name Haruka, Kantarou breaks the seal and becomes Haruka's master. As time goes on, Kantarou, Youko, and Haruka develop a close friendship. However, this relationship is threatened by Haruka's returning memories and his yearning to know more about his past.
The manga was first released in North America by ADV Manga in 2004. Afterwards, the US license was transferred to Tokyopop, who released 8 volumes before they shut down their American branch. Volumes 1–12 were available on JManga until its closure in May 2013. ;Volume list

Dōjinshi
Kinoshita and Higashiyama form a dōjinshi circle called Mad Cookie Monster. They individually go by the pseudonyms Wasabi Katsuo and Wasabi Maguro, respectively. This circle has released many dōjinshi for their own series, including Tactics, some of them containing explicit yaoi pornography. One of the rarest and best known of these titles is Love Sick, a 72-page dōjinshi containing an illustrated short novel and an explicit yaoi comic, featuring the pairing Haruka x Kantarou. Other dōjinshi based on Tactics are El Principe, which features mild Haruka x Kantarou, and Lil' Crazy, which features Raikou x Haruka.
