In the span of a single night, human history was redefined. Destroyed and rebuilt anew, New York City was transformed into Hellsalem's Lot, a metropolis blending humdrum city life with that of "The Beyond"—a mystical realm transcending human comprehension. Three years later, humans and otherworldly beings have managed to coexist in a city where violence and mayhem have become commonplace. Surrounded by a near-impenetrable barrier of fog, exchange with the outside world is strictly regulated, keeping the mysteries of The Beyond well-contained within. To maintain a balance, the secret society Libra protects both the city and the outside world from its dangers.

Leonardo "Leo" Watch, a victim of Hellsalem's Lot's unpredictable madness, was bestowed with "The Eyes of God," a supernatural gift that grants him superhuman sight but at the cost of his sister's eyesight. Having stayed in the city to research his condition, Leo seeks out Libra as his next lead. However, the organization finds that Leo's abilities can aid them in their cause and inducts him into their ragtag group in exchange for their assistance. Now an unlikely member of their team, Leo accompanies the fearsome but pure-hearted leader Klaus von Reinherz and the other colorful members of Libra on dangerous, high-stake missions to ensure the safety of a city that never sleeps.

Kekkai Sensen's pilot serialization ran in Jump SQ from the February to April 2009 issues under the title Kekkai Sensen: Mafuugai Kessha (血界戦線 ―魔封街結社―), which was later collected in the first volume. The official serialization started next year in Jump SQ.19 Vol.1 (2010/5), and continued until Vol.18, when the magazine was discontinued. The manga's second season, Kekkai Sensen: Back 2 Back, started the same year in the new quarterly magazine Jump SQ.Crown.

The series was published in English as Blood Blockade Battlefront by Dark Horse Manga from September 14, 2011 to August 7, 2018.

Blood Blockade Battlefront (also known as Kekkai Sensen) is a manga about Leonard Watch, he is dragged into the city of Jerusalem's Lot and has acquired a power called the "Eye of The Gods;" this makes him see things that others can't. Leonard becomes involved with the group Libra which is a group of supernatural humans, as well as monsters, who help non-humans that the "police" cannot.

The first problem I have with Kekkai Sensen is Leo's "Eye of The Gods," he always discovers a new ability with his eyes almost every volume. This makes it seem like the author can't decide what Leo can or ...

Alright everybody, prepare to read the only review of this manga you're ever going to find. Why's that? Because I'm confident that I may be the only one who actively reads it in the Western Hemisphere. Hopefully that'll now change with the advent of the anime.

Also, if you're looking, no scanlations exist for this, so go out and buy the Dark Horse releases if you want to read it in English (highly recommended)

We're gonna start by talking about the author. Yasuhiro Nightow is one of very few manga authors who is almost completely incomparable in style and content. Nightow is an Americanaphile. He loves ...
