Kekkaishi remains a definitive masterpiece of the "supernatural battle" genre. Created by Yellow Tanabe, the series concluded its 35-volume run in 2011, but it is currently experiencing a major resurgence in 2026 due to the Complete Edition (Kanzenban) digital rollout and rumors of a modern anime reboot.

The story follows Yoshimori Sumimura and Tokine Hazama, two "Kekkaishi" (barrier masters) who protect the mystical site of Karasumori from ancient spirits known as Ayakashi. Unlike traditional brawlers, Kekkaishi is celebrated for its tactical "Ketsui" (square barrier) combat system and its deep exploration of family legacy, sacrifice, and the burden of power.
