Aida Hiro is in his second year of high school. All of his previous encounters with love went without reciprocation., but it's not unheard of for a 17 year-old-boy attending an all boys' school not to have much love experience. Still, he cannot be happy, being both unable to whole-heartedly pursue the opposite sex and fulfill his romantic curiosity. However, he is able to experience true romantic love when he encounters the Ketai Girl, "Rin".

The grown-up say he is naughty but Keke feels he is just being curious like any other boy -- with a nagging mother who loves her family dearly, a father who is a philosopher-inventor, a mischievous puppy, Pipi -- and a smart cute alien (yes, from outer space) pocket-sized companion, MoMo, who dropped in one day and decided to stay. Keke has his ups and downs like he does good and bad things -- and stupid things! He likes cartoons, doodling on his drawing pad and he dreams of long holidays and of being grown-up -- and no longer under Mama's thumb. But in the meantime, normal life gets in the way like going to school and carrying his boring bento lunch made by Mama, so let us meet Keke and his family and may the fun begin!

A breach between Earth and the netherworlds has opened up over the city of New York, trapping New Yorkers and creatures from other dimensions in an impenetrable bubble. They've lived together for years, in a world of crazy crime sci-fi sensibilities. Now someone is threatening to sever the bubble, and a group of stylish superhumans is working to keep it from happening.

Supersonic monkeys, vampires, talking fishmen, and all sorts of different supernatural monsters living alongside humans—this has been part of daily life in Hellsalem's Lot, formerly known as New York City, for some time now. When a gateway between Earth and the Beyond opened three years ago, New Yorkers and creatures from the other dimension alike were trapped in an impenetrable bubble and were forced to live together. Libra is a secret organization composed of eccentrics and superhumans, tasked with keeping order in the city and making sure that chaos doesn't spread to the rest of the world. Pursuing photography as a hobby, Leonardo Watch is living a normal life with his parents and sister. But when he obtains the "All-seeing Eyes of the Gods" at the expense of his sister's eyesight, he goes to Hellsalem's Lot in order to help her by finding answers about the mysterious powers he received. He soon runs into Libra, and when Leo unexpectedly joins their ranks, he gets more than what he bargained for. Kekkai Sensen follows Leo's misadventures in the strangest place on Earth with his equally strange comrades—as the ordinary boy unwittingly sees his life take a turn for the extraordinary.
