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.

[Written by MAL Rewrite]


Kekkai Sensen adapts a select 12 chapters from the first 6 volumes of the manga it is based on while adding a new plotline and characters, culminating in an anime-exclusive ending. Aside from the first episode which adapts the three-chapter pilot, each episode adapts one chapter.

Episodes 1 and 2 were previewed at a screening at Odaiba Cinema Mediage in Tokyo on March 21, 2015. Regular broadcasting began on April 5, 2015. The final episode was originally scheduled to broadcast on July 4, 2015, but was delayed to October 4, 2015.

Sometimes, I don't get anime fans. If you've paid attention to the sales charts, you'll see that Blood Blockade Battlefront's current sales numbers are going toe-to-toe with Shirobako aka the most acclaimed and important anime series in recent times, and that just baffles me. I mean Kyoani’s own beautiful anime with believable character motivations, depth to its story, and (most importantly of all) actual challenges the characters have to overcome came out in the same season around the same time, and yet it just sold decently - which is below the studio’s usual standards. Okay fine, maybe this anime has a swanky soundtrack. Maybe it's ...

For those who have long awaited for a reboot for Trigun... you are going to have to wait a little longer. Until then you can watch Yasuhiro Nightow's other manga get adapted in what I am sure is going to be the best anime of the season that feels like the spiritual successor of Trigun. Kekkai sensen aka Blood Blockade Battlefront.

story and character 8/10: the story itself is not very complex. it can be simply put as an organization of super-powered people fighting against disorder in New York which has now turned into supernatural zone between the underworld and the real world that has been ...

Finally after months of waiting saw the Last Eps of Kekkai Sensen
And it was honestly a clusterfuck of nonsense, I loved it.
Nothing made real sense, chaotic story telling and events happening here and there with no real explanation.
Animation, art and OST were all beautiful
Fight scenes were fluid and characters were as crazy as ever
Storytelling is lost somewhere along the months of waiting for the last eps.
I cannot say exactly why I really enjoyed the last eps, just that I simply did
Overall I would never recommend this anime to anyone that focuses on story/plot or anything that makes sense or follows logic.
I do that those ...
