A Kiss Note is a powerful notebook that makes anyone who has their name written together will instantly fall in love if they kiss each other regardless of any circumstances. This magical and very familiar item belongs to an angel named Guri whose job as cupid is to create couples. However, she accidentally writes down Aino Seiji, a regular high school student, and unless he kisses someone, Guri will die. She convinces Seiji to go kiss his crush, Hiyama Akane, the school's popular girl who turns out has even stronger feelings for him, bordering on obsessive and psychotic. Eventually Akane and Seiji come together but not before Guri decides that she likes Seiji as well. What seems awesome to most guys becomes hell for Seiji who just wants a normal relationship with girls.

Satou Fuuka is an orphan. Her aunt, who was her guardian, absconded in the night, leaving her with no money. Her parents wanted her to go to school, so she was looking for a job to cover her school expenses and rent (plus living expenses, though she didn't mention it). She goes to be interviewed for a part-time house helper job but is rejected before she can say anything, because the guy offering the job is the eldest for 4 brothers and it's an all-male household. She pours out her story, so he takes pity on her (even though he'd pointed out that she can't really take a part-time job if she doesn't have a guardian) and offers the job as a live-in position. However, he has one condition: she's supposed to disguise herself so his brothers don't take an interest in her. Her disguise: lots of towels around her body, so she looks fat; makeup so she looks old (39); plus her hair is all loose and she's wearing glasses.
The brothers are: Tsukasa (eldest, apparently already working); Akari (second son, first year college student with a wider strike zone for women than Tsukasa thought); Kairi (third son, genius high-schooler and Fuuka's classmate); Minato (youngest, first year middle-schooler who's a blue-eyed blond). Incidentally, Fuuka notices that none of the brothers look related.

Ooyama Takeru, a young normal yet perverted minded guy, got accepted and now goes to a school that, unknown to him, was where combat and magic is used.

Finding out that there are many girls there that just don't like him, he is told that everyone there uses a special magic ability while using an item or weapon called a Maken. Later, he finds that no Maken is acceptable for him and doesn't know what to do, since in this school the students get into duels that showcase their magic and combat power, to which he seemingly has none.

In the world of Eluveitie, elves and dark elves have been warring since ancient times. The one thing that could tip the balance for either side is a half-elf child born from the nameless Earthling main character's seed. This is a tale of the drama and tragedy of the battle for one generic harem lead's baby batter.

In the near future, a Japanese scientist engineers a powered exoskeleton called "Infinite Stratos" (IS). Possessing technology and combat capabilities far more advanced than any other weapon system, the IS threatens to destabilize the world. Faced with such an overpowering weapon, the nations of the world enact the "Alaska Treaty", which states that IS will never be used for military combat and that existing IS technology must be equally distributed to all nations, to prevent any one nation for dominating the others. The introduction of the IS does however have a major effect on society. As IS can only be operated by women, the power balance between men and women is broken, with women coming to dominate society over men.

Ten years after the first IS were introduced, the world has entered a new age of peace. The peace is shattered, however, by an unexpected discovery. A 15 year old Japanese boy, named Ichika Orimura, is discovered to be capable of operating an IS. Realizing the potential, Ichika is forced by the Japanese government to attend the prestigious Infinite Stratos Academy, an international academy where IS pilots from all over the world are trained. Thus his busy school life surrounded by girls begins.

The stage is set in the prestigious Private Joshi (girls) Oka High School, more commonly known as Joshi High. It became co-educational a few years ago, but females still heavily outnumber the males. So small is the number of men that it could be easily counted. While one would think guys would be pampered in such a harem school, the reality is far from heavenly. It is the world of female domination.

The story continues where the first season left off only months into the future. Yuokai Gakuen has been repaired and the new semester is underway. Tsukune and gang are back, and more powerful then ever. Anti-Thesis's true identity is revealed. With new adversaries looming on the horizon, and something much more sinister than the gang has ever faced before.

Tsukune is battling with the monster inside him. With the help of Moka, Mizore, Kurumu, Ruby, and Yukari. Tsukune trains to get his vampire blood under control and the strength to protect what he holds dear.

The new season focuses more on the girls, their past, and their families. New confrontations await them. New friends and allies will join them by their side. Together they will discover the secrets of Moka's rosary, and her lineage...

The demon king having cursed the human race by removing their ability to produce female children so that they would go extinct has had his plan foiled by the elves who made men breedable by giving them eggs(balls) ♂ which would make them become women when taken away from them.

A world of magic and swords.

Born into an aristocratic family of a large country, a boy with insufficient magic power bade farewell to his unlucky daily life. Because of his encounter with a Demon, his fate began to change. This destined meeting changed the boy’s life, affected his surroundings, and soon after, shook the entire world.

This is his tale.
