Kekkaishi

The Kekkaishi's mission is to exterminate the Ayakashi that appear within the Karasumori site. As legitimate heirs, Yoshimori Sumimura and Tokine Yukimura carry out their family tradition as the Kekkaishi. Following an incident that occurred five years ago, Yoshimori vows to protect Tokine from ever getting hurt.

During the day, Yoshimori and Tokine are normal students living a regular school life. At night, they protect the Karasumori site as Kekkaishi. One day, the Ayakashi Tsuchigama invades into the Karasumori school grounds. Yoshimori must run through the Tsuchigama's rain of attacks in order to destroy the Ayakashi.

Yomi Kasuga, a Demon Tamer, pays a visit to the Yukimura family under orders from the Shadow Organization. Her arrival causes Tokine to recall the painful memory of the day her father Tokio died. Yomi reveals herself to be an enemy and explains her goal of taking over the Karasumori site in order to strengthen her demon, Yoki. Imprisoned, Yoshimori and Tokine find themselves in danger!

The Karasumori's power causes Yoki to go out of control. Even Yomi is unable to stop her demon now. Hakudo and Odo, who were sent by the Shadow Organization to pursue Yomi, arrive and destroy Yoki. Yomi is then taken into custody for defying orders. As she departs, Yomi learns from Yoshimori the true meaning of kindness.

Yoshimori meets a human ghost who used to be a patissier. The friendly ghost gives Yoshimori some tips on how to bake better sweets. Although Tokine coldly tells the ghost to pass on to the after life, that very same night, Yoshimori senses something transforming into an Ayakashi at the Karasumori!

Yurina Kanda, one of Yoshimori's classmates, is a girl who can see ghosts and spirits. To see one of the 77 wonders of Karasumori Academy - the unseasonable blooming of cherry blossoms - Yurina sneaks into the school grounds late at night. There, she witnesses Yoshimori and Tokine in the midst of exterminating the Ayakashi!
