Harem
A harem includes three or more characters who potentially show romantic interest in a male protagonist. The sex, gender, or orientation of the harem members is irrelevant as long as they exclusively, or at least primarily, are vying for the affections of the same individual - who may or may not reciprocate towards one, several, or none of these romantic rivals.

    Fuyuzora Kogarashi has spirit abilities, and has been possessed by ghosts since he was a kid. This has caused a lot of trouble in his life, but now he has learned to fight back against the evil spirits! Unfortunately, he's now also very poor, homeless, and hoping for a happier, more normal, high school life. In his search for housing, he's introduced to a very cheap boarding house called Yuragi-sou, which was formerly a popular hot springs inn. It's so cheap because the house is haunted by the spirit of a high school student whose corpse was found there.

    Kogarashi doesn't think this is going to be a problem for him, and the rest of the house's tenants appear to be sexy women. While relaxing in the hot springs, though, he finds there is an issue with his ghost-banishing plan; Yuragi-sou's ghost is a 16-year-old girl named Yuna, who lives in his room. Kogarashi has no desire to hurt a ghost girl, and instead he ends up agreeing to help her to figure out her unfinished business. That way, she can move onto the afterlife before turning evil and falling into hell. Once it is clear that he is fine with Yuna, the other tenants reveal their own supernatural secrets--his life in Yuragi-sou is going to be far from ordinary!

    Kanade Amakusa is a high-school student who is suffering from a curse called "Absolute Choices" (絶対選択肢, Zettai Sentakushi). This curse requires him to select an action from a list of two or three options that appear before him at any time, and has no control over what choices appear. Many of them are weird or perverse and as a result, the curse has tainted his reputation with his classmates and other people around him, making his life very difficult.

    However, one day, a choice he makes on his way home from school causes a mysterious, beautiful young girl to fall from the sky. Amakusa discovers that she was sent from the God World to assist him in completing a series of missions given to him directly by God himself. After completing these missions, the "Absolute Choices" curse will be lifted from Amakusa; but should he fail in completing any of the missions, he will be stuck with the curse forever.

    15 years ago the world discovered magic as well as mythical beings (basically beings from various legends) in another dimension. Humankind learned to summon these dangerous mythical beings and use their power to great effect. 7 countries formed contracts with these "Diva" and gained their alligence as a result. Diva will chose their summoners on their 14th birthday and give them a stigma. Schools have been set up to train summoners and magical swordsman (basically bodyguards that give the summoners time to cast their spell) as a result.

    15 years later after the finding of magic Hayashizaki Kazuki is chosen as a summoner and given a stigma to indicate that. This is surprising since males aren't chosen as summoners due to their low amount of mana compared to females. As the first male to be a summoner Kazuki is under a lot of scrutiny by almost everyone.

    To complicate matters his sister (who's a magical swordsman) is against him going into summoner school to train there as a summoner. Because summoners and magical swordsman have a cat mouse thing going on where summoners look down on magical swordsman as inferior so his sister naturally is against him going there. She'll stop him even if it means going to war.

    Kazuki however is determined to thrive in summoner school and have already determined to give it his all. Even if he's the lowest ranked student (ranked E) and his fellow students intend to demean him he'll prove himself as the strongest summoner.

    Adaptation of the light novel written by Mihara Mitsuki and illustrated by CHuN.

    The Private Aichi Symbiosis Academy was originally a high school for high-class girls. When it became co-ed, the girls, out of fear, asked to be permitted to bring weapons to school. When that was enforced, a five-member vigilante corps-like organization called the "Supreme Five Swords" was also formed.
    After many generations, the five swords eventually became a group which corrected problematic students, so the academy started proactively accepting such students in order to correct them.
