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.

When an ogre-user and member of the Urakai named Yomi who knew Tokine's father arrives in town, Tokine is forced to remember her fathers death. Even though the Urakai have been introduced as being on the side of "good" Yomi is strangely suspicious, and not completely trusted.

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.

This episode begins where the last ended with the Kekkaishi cleaning up the mess created by Yomi and Yoki at karasumori. Shigemori explains to Yoshimori that within the Urakai is a group of users called the Yagyou who are an operations squad of the Urakai, and that the leader of the Yagyou is Yoshimori's older brother, Masamori. The episode continues to follow the story of Yoshimori's dealings with a ghost that is having trouble passing on.

Because of the power of Karasumori a huge cherry tree blossoms in front of the school completely out of season. The tree attracts curious students as well as power hungry Ayakashi.

This episode continues where the last left off with the spirit of a pastry chef that refuses to pass on. Yoshimori helps him throughout the episode to fulfill his dying wish so he can pass on in peace.

Yoshimori trains a lot and tries to best Tokine as usual. His grandpa, Shigemori, mentally remarks how much power Yoshimori has. Yoshimori at the end breaks a boulder... and the garden.

A handsome teacher shows up secretly attacking students. Yoshimori is suspicious of the guy when he sees Tokine happily walking next to the guy and thinks about warning her of him being a possible dangerous player. At night, they sense an abnormality inside the school and they discover it is the teacher with three snakes wrapped around him. The teacher is actually a person with special powers but they still sense an ayakashi. It turns out that he was possessed by a parasitic ayakashi and they destroy it. The teacher is distraught that he attacked a student and is really nice by nature although he is still slightly perverted.

Yoshimori as a cake lover is obsessed with the legendary chocolate cake that his dad mentioned to him that is offered secretly to only 7 people at 5 AM at a specific cake shop. In order to hold a place in line, Yoshimori sends his shikigami but he is tired out and can't focus when fighting an ayakashi at Karasumori. Tokine worries about him but when she finds out the reason she becomes angry. Yoshimori then discovers that Shigemori ate his share of the chocolate cake much to his dismay. The next day Tokine reluctantly calls Yoshimori for help to kill a cockroach. Yoshimori manages to do so after Tokine accidentally pushes him on the ground smashing it. Afterwards, Tokine continuously avoids him but eventually gives him a thank-you gift: a T-shirt and the legendary chocolate cake.

It's another night of Kekkaishi duty. Yoshimori encounters three minor ayakashi, Honetarou, Uhosuke, and Nagao, and easily captures them. However, Madarao's old companion, Kouya, shows up and in anger attacks everyone, including his followers. After a brief flashback of Ginro (Madarao) and Kouya's happy past gone wrong at the hands of the humans, Kouya gains power from Karasumori and transforms. Yoshimori releases the seal on Madarao revealing his real form. Madarao and Kouya then battle.

After a long battle, Madarao is weakened and begins to accept death believing that Kouya will die as well but Kouya gains even more power from Karasumori. Just as Madarao is about to give up, Yoshimori steps in and tells Madarao that his master is not allowing him to die and thus Madarao stands up. The two work together and strike Kouya down. The dying Kouya tells Madarao to kill him but Madarao can't because he has no power left, but Kouya refuses to die at the hands of a human and so Karasumori lends its power to Madarao, finishing off Kouya. But before the group can celebrate, Madarao's true ayakashi nature reveals itself and starts attacking Yoshimori. But Yoshimori, with the help of Hakubi and Tokine, successfully seals Madarao once again through much difficulty.
