Plot
In the year 2021, mankind is ravaged by the epidemic of Gastrea, a parasitic virus, and is forced to live within the Monolith walls, which are created from Varanium: a metal that is able to subdue Gastrea. Soon, children who were born with the Gastrea virus and obtained superhuman abilities as a result, are discovered and dubbed "Cursed Children". Due to the Gastrea virus' intervention, the Cursed Children could only be female. Civil Securities are formed to specialize fighting against Gastrea, operating with the pair of an Initiator, who are cursed children, and a Promoter, serving to lead the cursed children. Ten years after the epidemic, Rentarō Satomi, a high school student who is also a Promoter in Tendō Civil Security Agency owned by his childhood friend Kisara Tendō, along with his Initiator, Enju Aihara, conducts missions to prevent the destruction of the Tokyo Area and the world.

Tendō Civil Security

 * Rentarō Satomi (里見 蓮太郎)
 * Rentarō is a second year student in Magata High School and a Promoter in Tendō Civil Security. Rentarō's parents died in the war against Gastrea ten years ago, and was adopted by the Tendō family, but left the family along with Kisara. Rentarō lost his right leg, right arm and left eye in a fight with Gastrea to protect Kisara, and was saved by Doc's "New Human Creation Plan" which replaced his lost limbs with Varanium. Due to his kind and sincere nature Rentaro is one of the few sympathizers of the cursed children. He usually goes to extreme lengths to help them. This trait also leads many cursed children to either take an interest in him or become infatuated with him. He uses an XD and is a beginner in Tendō style martial arts in the beginning of the story.

 * Kisara Tendō (天童 木更)
 * Kisara is the president of Tendō Civil Security. Originally from the Tendō clan, she left the family after a certain conflict along with her childhood friend Rentarō. Kisara's kidneys are barely functioning due to the trauma of witnessing her parents being eaten alive by Gastrea. Believing that her parents' deaths were connected to the Tendō family, she swore to avenge them and has been searching for the murderers. She is extremely skilled at the Tendō style of martial arts, but is unable to fight for extended periods of time due to her condition. Kisara has feelings for Rentarō, who has shown the attraction to be mutual, but their attempts to communicate their feelings towards one another are usually interrupted, most of the time by Enju. However, her obsession with exacting revenge on the Tendō clan is a source of concern for Rentarō, who fears it may one day lead to them parting ways.

Manga
A manga adaptation illustrated by Morinohon was serialized in ASCII Media Works' Dengeki Maoh magazine from August 27, 2012 to June 27, 2014.

Anime
An anime television series adaptation animated by Kinema Citrus and Orange was announced at Dengeki Bunko's Autumn Festival 2013 on October 6, 2013, and premiered in April 2014. The series was picked up by Crunchyroll for online simulcast streaming in North America and other select parts of the world. The anime has been licensed by Sentai Filmworks for a digital and home video release in North America. Muse Communication licensed the anime to Southeast Asia and South Asia region

The opening theme is "black bullet" by fripSide and the ending theme is "Tokohana" (トコハナ) by Nagi Yanagi.

Reception
Anime News Network had five editors review the first episode of the anime: Hope Chapman, while finding it watchable with its action scenes despite being another lazy light novel adaptation, found the female supporting cast reprehensible, singling out the portrayal of Enju Aihara as otaku bait; Bamboo Dong and Carl Kimlinger similarly praised it for being decently written and leaving enough room for story and character developments, the former saying that it might get better with later episodes while the latter criticized it for being the same as every other anime of its ilk; Rebecca Silverman said that the premise had intrigue with visuals that catch the eyes' attention but it needs to work on its pacing and story developments to reach its potential. The fifth reviewer, Theron Martin, while finding the story schematics generic and filled with otaku trappings was hopeful because of the technical aspects that complement the action scenes and the sense of intrigue throughout, concluding that "it looks like it could be an entertaining (if not necessarily original) action romp, especially if the kinks get ironed out." Kotaku's Richard Eisenbeis was negative towards the series, saying it had a good concept but was bogged down by an amalgam of genres that don't go together, follows a formulaic blueprint set by other anime series and is filled with plot holes that require a suspension of disbelief, concluding that, "In the end, I simply would not recommend Black Bullet to anyone. It's a mess of an anime." Allen Moody, writing for THEM Anime Reviews, was critical of the series' cliché harem aspects but gave praise to both Seitenshi and Enju, crediting the former's trait of being "gentle while still being strong and decisive," and the latter for her relationship with Rentaro being "emotionally deeper and more complex than a lolicon crush." Moody also gave praise to the action scenes for their mixture of both CG and traditional animation, and the "imaginatively conceived" designs of the Gastrea that occupy them.
