- Bleach -

Ichigo Kurosaki is a teenager gifted with the ability to see spirits. His life is drastically changed by the sudden appearance of a Soul Reaper; the one who governs the flow of souls between the human world and the afterlife named Rukia Kuchiki, who arrives in search of a Hollow, a dangerous lost soul. When Rukia is severely wounded defending Ichigo from the Hollow, she attempts to transfer half of her reiatsu energy to Ichigo so that he can defeat the Hollow. However, Ichigo takes almost all of her energy, transforming into a Soul Reaper and allowing him to defeat the Hollow with ease. With her powers diminished, Rukia is left stranded in the human world until she can recover her strength. In the meantime, Ichigo must take over Rukia's role as a Soul Reaper, battling Hollows and guiding souls to the afterlife realm known as the Soul Society.

As time passes and Rukia has yet to return to the Soul Society, her Soul Reaper superiors learn about her whereabouts and actions and sentence her to death for performing the illegal act of transferring her powers. Although he is unable to stop Rukia's departure to the Soul Society, Ichigo resolves to rescue her with the aid of several of his spiritually aware classmates, Orihime Inoue, Yasutora Sado, and Uryu Ishida, and the ex-Soul Reapers, Yoruichi Shihoin and Kisuke Urahara. Once at the Soul Society, Ichigo and company battle against the elites of the Soul Reaper military and strive to reach Rukia before her execution. It is revealed that Rukia's execution and Ichigo's rescue attempt both had been manipulated by a high-ranking Soul Reaper, Sosuke Aizen, who was previously believed to have been murdered, as part of a far-reaching plot to take control of the Soul Society. Aizen betrays his fellow Soul Reapers and allies himself with the strongest of the Hollows, the Espadas, whom he enhances. Aizen thus becomes the main antagonist of the series, and the Soul Reapers form an alliance with Ichigo.

At this point, Bleach chronicles the war between the Soul Reapers, the Espadas, and Aizen. After each of the involved's eventual defeats, Ichigo undergoes intense training with his father Isshin who turns out to be a former Soul Reaper to become strong enough to battle Aizen alone. As Aizen is weakened by his battle with Ichigo, a spell that Urahara had previously hidden within him activates and seals him, thus ending the conflict and leaving the Soul Society to imprison him. As a result of using all of his Soul Reaper powers to defeat Aizen, Ichigo loses them and becomes an ordinary human once again.

Seventeen months later, Ichigo meets "Xcution", a group of humans possessing Fullbring powers based on Hollows and want Ichigo to absorb them. Ichigo starts training to regain his Soul Reaper powers by first developing his own Fullbring following the appearance of Shukuro Tsukishima, the former leader of Xcution who is targeting his friends. After developing his Fullbring, Ichigo is betrayed by Xcution's current leader Kugo Ginjo, a former Substitute Soul Reaper who had his memories rewritten to act as Tsukishima's enemy and help Ichigo gain powers to steal them. With help from Soul Society, Ichigo regains his Soul Reapers powers and starts fighting Ginjo's group alongside Soul Society's forces. The Soul Society forces end victorious with Ichigo killing Ginjo and Byakuya presumably killing Tsukishima.

Following these events, A group of Quincies called the "Vandenreich" declare war on the Soul Society. Ichigo once again ventures to Hueco Mundo.

- Jigoku Shojo (Hell Girl) -

Most episodes are self-contained short stories in which the series narrates the suffering of a different individual caused by one or more antagonists. In general during each arc, the protagonists' dramas are explained in detail from the start of their grudges, through the escalation of their torment until it becomes unbearable and they resort to accessing the Hell Correspondence website. Although in general, the client gives the protagonist a chance, he or she usually ends up pulling the string on his or her doll and sending the antagonist to hell. Once they have pulled the string, before taking the antagonist to hell, Ai Enma punishes the person for his or her sins with the help of her companions.

In the first season, the story soon follows a journalist named Shibata Hajime, a former blackmailer, and his daughter Tsugumi who shares a strange connection with the Hell Girl as they investigate the truth behind the Hell Girl. In the second season, a mysterious young girl from Hell, named Kikuri who is able to travel freely between Earth and the Twilight realm where Ai resides, is introduced. Later, the plot centers around Takuma Kurebayashi, a boy who is blamed by his townsfolk for causing disappearances around the town that are in reality caused by the townsfolk using the Hell Correspondence. In the third season, Kikuri returns to recruit Ai's assistants along with a yokai named Yamawaro, who accepts an old offer from Ai to become her fourth assistant. The story follows Ai's mysterious possession of a young schoolgirl, Yuzuki Mikage.

- Ouran High School -

 

Haruhi Fujioka is a scholarship student at the prestigious Ouran Academy, a fictional high school located in Bunkyo, Tokyo. Looking for a quiet place to study, Haruhi stumbles upon the Third Music Room, a place where the Ouran Academy Host Club, a group of six male students, gathers to entertain female "clients".

During their first meeting, Haruhi accidentally knocks over and breaks an antique vase valued at ¥8,000,000 (US$80,000 in the U.S. English manga) and is told to repay the cost in service to the club. Haruhi's short hair, slouching attire and gender-ambiguous look cause her to be mistaken by the hosts for a male student. 

The hosts all agree that Haruhi would be a good host, thus making her join the host club. Ultimately she agrees to join the Club as a host herself (dressed as a male) in order to pay off her debt. She agrees to join since she does not mind hosting as long as she can pay the debt off faster. The hosts do later find out that she is, in fact, a girl. They keep this a secret, so no one will be able to tell. 

The Ouran Private Academy encompasses kindergarten to twelfth grade (along with a university). Most students come from wealthy families, but in special cases, merit scholarships are granted to exceptional students from a lower income bracket. The school's unofficial motto is "Lineage counts first, wealth a close second," meaning students with stellar family backgrounds but low socioeconomic status may be given top priority over those from rich families with lesser pedigrees.
