Like the Takarazuka Revue, the young women who go to the arts academy Kouka Kageki High School play all the parts of musical theater, be they female or male.

Ai Monogatari: 9 Love Stories

Ai Monogatari: 9 Love Stories

Young love remains in the hearts of so many; and it is this love that is explored within nine stories. A man meets his first love again -- a wild girl from his youth that was into the Beatles; a high school Rugby manager meets the team's star again after so many years; a salaryman falls for a mobster's girlfriend; and another leaves his small-town love to live life in a big city, and meets a girl that resembles her ten years later. Relationships aren't always as simple as just loving someone; sometimes it takes time to learn how to love.

Having recovered from the injuries he had sustained, Zero returns to Cross Academy to resume his role as prefect. Though, not long after he resumes his role, members of the Supreme Vampire Council ambush Zero with the intent to execute him for the murder of the pureblood, Shizuka. Luckily when Kaname intervenes, he sends the council away and insists that they stay out of school affairs. However, whilst Kaname continues to hide the truth about Shizuka's death, there are others who grow suspicious of what happened that night and what the dorm president is hiding. Meanwhile, Yuuki begins to have flashbacks, leading her to investigate her blood-stained past: what will she find, and will she continue to be tempted by an offer from Kaname?

Vampire Knight

Vampire Knight

Cross Academy is a school with a difference: in a unique and experimental setup designed by the headmaster, it has a Day Class consisting of ordinary humans and a Night Class filled with vampires. Yuki Cross and her friend Zero Kiryu are school prefects whose job it is to make sure the secret of the Night Class is always safe; they patrol the school grounds at night and supervise the switchover of classes at dawn and dusk to prevent any 'accidents' from happening. While Zero is suspicious of vampires and hates the idea of sharing the same space as them, Yuki admires the Night Class for their beauty and sophistication; she is especially intrigued by their charming leader, Kaname, because he once saved her life. However, as Yuki quickly learns, not all vampires are amiable like the Night Class, and as terrible events unfold, Yuki must ask herself whether in a world where vampires are the hunters and humans are the prey, peaceful coexistence can really be achieved.
