# Karneval (manga)

Karneval (Japanese: カーニヴァル, Hepburn: Kānivaru) is a Japanese manga series by Tōya Mikanagi which began serialization in the monthly josei manga magazine Monthly Comic Zero Sum published by Ichijinsha on August 28, 2007. There are currently twenty-eight volumes released in Japan. The series follows Nai and Gareki, who join a defense organization called Circus in hopes of finding a man named Karoku. However, they are unaware that Karoku belongs to a secret organization called Kafka, which is responsible for performing human and animal experiments called Varugas. A 13-episode anime adaptation by Manglobe aired between April and June 2013.

## Plot

Nai searches for someone important to him, with only an abandoned bracelet as a clue. Gareki steals and pick-pockets to get by from day to day. The two meet in a strange mansion where they are set up, and soon become wanted criminals by military security operatives. When Nai and Gareki find themselves desperate in a hopeless predicament, they encounter none other than the country's most powerful defense organization, "Circus".

## Characters
### Main characters
#### Nai Muhinyi (无)

    Voiced by: Hiro Shimono (Japanese); Sean Michael Teague (English)
    Nai Muhinyi is the main protagonist of the story. He claims to have always been living with a man named Karoku in a forest near Karasuna. When Karoku does not appear one day, Nai ventures outside and finds a trail of blood leading from their home to the sea, and a left-behind bracelet (Circus I.D.). Feeling scared and lonely, he sets out to try finding Karoku with only the abandoned bracelet as a clue. He eventually meets Gareki, who saves Nai from a mansion where a Varuga woman named Miné was keeping him captive. This marks the beginning of their travel together. Despite his unworldly ways, he has an acute sense of hearing that is more well-developed compared to other people's. Akari, a research doctor at Circus reveals that Nai has the cellular structure of a human and a "Niji", a small, delicate creature found in the forest he came from, and that these cells have managed to coexist unlike the Varuga. He also said that Nai is successfully existing as a new species and that if they were to describe the person who accomplished this, they would certainly be called a genius and that to produce a being like Nai, the creator must have been very devoted.

#### Gareki (花礫)

    Voiced by: Hiroshi Kamiya (Japanese); Greg Ayres (English)
    A 15-year-old boy who gets money by robbing rich people's mansions. He is very intelligent and sharp, his strong point being his knowledge of mechanics. He is also a skilled shooter and likes to carry around a gun. Gareki distrusts people and is not very sociable, stating that he hates associating with others. However, despite his arrogant and distant attitude, he does have a more caring side that he does not like showing, seeming to have a soft spot for his friends on the second ship and Nai. He originally thought to use Nai for his robbing schemes but later joins him to find Karoku. When Nai tells Gareki about Karoku knowing that they were together, Gareki realizes that Karoku wants to keep him away from Nai. Gareki works with the Circus organization to help defeat Kafta and Varuga, who killed Tsubaki and Yokata.

### Circus

Circus is a defense organization that works for the government. They perform raids to capture criminals and solve crimes that the Security Force otherwise cannot handle. After their raids, they put on shows as an apology for scaring the citizens.

#### Yogi (與儀)

    Voiced by: Mamoru Miyano (Japanese); Christopher Bevins (English)
    The Second Ship's Fighter Yogi is an eccentric 21-year-old man who is always bright and cheerful. He is Hirato's subordinate. Despite his age, he tends to act like a child. He wears a white allergy patch on his left cheek, that, when removed, causes him to become extremely violent, as well as changing his hair color. While he states that battles make him nervous, he is still a skilled fighter. During the Circus's public shows he usually wears a cat costume named "Nyanperowna" and hands out candy to children. His weapons are two thornlike épées, and the name of his special attack is Dornkiste (German for "thorn chest"). He calls Nai "little Nai". He looks after Gareki and Nai with Tsukumo. Though Yogi cares for everyone, he has a soft spot for Gareki.

#### Tsukumo (ツクモ)

    Voiced by: Aya Endō (Japanese); Jad Saxton (English)
    Another fighter of the Second Ship's crew, and Hirato's subordinate. She is always wearing a serious expression on her face, is down to earth, and very dedicated. Tsukumo is a skilled acrobat and her beauty is complimented by both men and women. She is the most level-headed out of the group, and tries to be the shoulder to lean on even though she has a hard time understanding others emotions. Tsukumo is close to Nai, and cares about his well-being. She hated insects ever since she was a child, which was shown when Yogi mentioned that the species "Niji" has a diet of primarily insects.

#### Hirato (平門)

    Voiced by: Daisuke Ono (Japanese); Ian Sinclair (English)
    The Second Ship's Captain. A very polite 27-year-old man who does not take his work too seriously, but does his job well. His smile can be deceiving and people have a hard time figuring out his true intentions and feelings. Upon taking Gareki and Nai on board his ship, he entrusts them to Yogi and Tsukumo. His weapon is a cane, and the name of his special attack is Vakuum (German for "vacuum").

#### Eva (イヴァ, Iva)

    Voiced by: Yōko Honna (Japanese); Jessica Cavanagh (English)
    The Second Ship's 25-year-old Lieutenant. She appears to be soft and feminine when she is with women but acts masculine when she is with men. She is very fond of Tsukumo.

#### Akari (燭)

    Voiced by: Daisuke Hirakawa (Japanese); David Matranga (English)
    A doctor working for the government. He is a complete workaholic; a fact which often grates on the nerves of the people around him. He does not seem to have a good relationship with Hirato, and Yogi seems to be slightly scared of him. It is implied that he is wealthy. Due to the reserved, unfeeling and stoic front, he puts up most of the time he is rather disliked by many, yet he is actually a very gentle person who cares for living beings, Nai being one of them.

#### Jiki (喰)

    Voiced by: Yuichi Nakamura (Japanese); Aaron Dismuke (English)
    A soft-spoken botanist who also First Ship's fighter. Jiki seems to have feelings for Tsukumo from the Second Ship and he does not get along very well with Eva.

#### Tsukitachi (朔)

    Voiced by: Koji Yusa (Japanese); J. Michael Tatum (English)
    The First Ship's Captain. An easygoing member of Circus who does not care about the small things. He often comes off as being quite rude, but he is simply being straightforward with his observations. He is the same age as Hirato.

#### Kiichi (キイチ)

    Voiced by: Eri Kitamura (Japanese); Alison Viktorin (English)
    The First Ship's fighter. A female member of Circus who is strong-willed, a sore loser and perfectionist. She considers Tsukumo her rival.

#### Azana (アザナ)

    Voiced by: Nobuhiko Okamoto (Japanese); Jerry Jewell (English)
    Akari's long-haired assistant, originally stationed in Life Division but occasionally help in Research Tower. He is very gentle and a bit of a klutz. His face is usually littered with band-aids. His family was killed by Varuga.

#### Ryoushi (療師, Ryōshi)

    Voiced by: Kenichi Ogata (Japanese); Bob Magruder (English)
    A white-bearded doctor working for the government, also known as the "Healer". He is very easygoing and happy-go-lucky despite his doctor status. He also likes to compliment girls and to act bubbly, like a kid. He does not take things seriously like Akari does, and enjoys prancing around laughing happily. However, when he sees Yogi, he sometimes throws him out of the room, quite literally.

### Kafka

Kafka is a dark, hidden organization/place that does illegal genetic research. Their ultimate goal is to bring about the growth of incuna cells in human beings. They oppose the government and work against Circus.

#### Karoku (嘉禄)

At the end of the second episode of the anime, however, it is implied that Karoku is held somewhere by Kafka. He is seen in a dark greenhouse full of roses with Eliška, the young granddaughter of a rich industrial who is implied to be the leader of Kafka. He sends messages to Nai through brain waves. He calls Nai his "special child". During the incident at the Misty Mansion, it is revealed that there are two Karokus; one that appears to be Karoku but is not, and one that is the original Karoku. Gareki and Nai rescue the presumably dead original Karoku but Akari brings him back to life. When revived, he has no memories of who Nai is. After Nai protects him from dying, Karoku remembers Nai again.

#### Eliška (エリシュカ, Erishuka, alt. Eleska)

    The 14-year-old granddaughter of Palnedo, the CEO of Gald. She grew up in an environment where she was treated like a princess, and as a result she was brought up to be a selfish girl who does not know how to be considerate towards others. She is revealed to have feelings for the fake Karoku. At one point when she hears Karoku say there is a special child in Circus, she believes him to be talking about Tsukumo, which makes her feel jealous. She seems to be unaware of Uro and her grandfather's true intentions and schemes.

Meanwhile, Tsukumo and Hirato arrive outside the mansion where Miné has died, and they receive a call of a train hijacking. Nai and Gareki jump aboard this train to leave town, unaware of the hijacking. Just then, Tsukumo and Hirato appear as they take on their hijackers in front of Nai and Gareki. Eliška and Palnedo are held hostage by the hijackers because Palnedo had massive layoffs from his company. Tsukumo and Hirato subdue the hijackers and free Eliška and Palnedo. With the train packed with explosives, the best option is to evacuate and derail the train. However, with Nai's help, Hirato locates the signal device, while Gareki tells Hirato to disconnect the rear car in order to terminate the signal.

Since this realization, Gareki confronts Nai for cutting ties with him, finding out that Nai was contacted by Karoku telepathically. This leads Gareki to believe that Karoku is an enigma.

Yogi attempts to trap Yotaka, now with black wings, in a cage of thorns, but Yotaka overpowers Yogi when the latter mentions Gareki's name. As Meiga captures Nai and Tsubame after finding them hiding in an open shed, Gareki kicks Meiga out of the blue and confronts Yotaka for his gothic looks.

Tsubame is able to temporarily restore humanity in Yotaka through her bond as a twin.

Failing to track down the Usagi in the streets, Yogi and Kiichi deduce that it will show up at the plaza theater. Meanwhile at the plaza theater, a play commences with Jiki as a soldier next to Tsukumo as a mermaid in a sealed jar. The play takes a bad turn when the Usagi welds the trap door of the jar shut.
