Plot
Taro Sakamoto used to be an unrivaled hitman, earning legendary status in the underworld. But one day, the unthinkable happened. Sakamoto fell in love. He started dating, retired, got married, and had a kid, growing overweight as a result. Though now working as a humble convenience store owner, the world of hitmen still follows him. Sakamoto, along with Shin, a young man with telepathy and employee at his small store, will protect his humble life and family, or die trying.

Sakamoto's Convenience Store

 * Taro Sakamoto (坂本 太郎)
 * An ex-hitman who gave up a life of wealth and crime to marry Aoi, now working as a humble convenience store owner. He has gained a lot of weight, and has become more laid-back, but still has his superhuman skill and strength from his hitman days, though he is now 30% of his prime. During extreme situations, he loses all this fat, and becomes skinny, becoming twice as powerful as before.

During extreme situations, he loses all this fat, and becomes skinny, becoming twice as powerful as before.


 * Shin Asakura (朝倉 シン)
 * A former hitman who admires Sakamoto, and now works for him at his convenience store. He is known as Shin the Clairvoyant because he has the ability to read minds. A running gag is Sakamoto imagining killing him when he annoys him.


 * Lu Xiaotang (陸 小糖)
 * The daughter of a Chinese mob boss. She is airheaded, but can be analytical and competent when necessary. While she does not do much fighting, she is very capable, as she uses a fighting style that mixes Tai Chi with Drunken Fist.


 * Aoi Sakamoto (坂本 葵)
 * Sakamoto's wife who loves her husband very much, despite his history as a hitman. She is also the reason why Sakamoto abandons killing and shows him a better path to protecting his loved ones.


 * Hana Sakamoto (坂本 花)
 * Sakamoto and Aoi's 6 year old daughter.


 * Heisuke Mashimo (眞霜 平助)
 * A hitman who specializes in sniping. He is very gullible and hyperemotional, but his skills with a sniper rifle easily make up for it, even holding the all-time record at the JCC (Japan Clear Creation) (anonymously, due to simply forgetting to write his name). After his encounter and encouragement from Sakamoto, he becomes a regular in his shop, and sometimes his scout.

The Order

 * Yoichi Nagumo (南雲 与市)
 * Sakamoto's classmate in the JCC who would serve as an Order member with Sakamoto until his retirement. He is very cheerful and casual, which bely his skill, and he enjoys antagonizing his fellow Order members. He locates Sakamoto after he gains a bounty and does what he can to maintain Sakamoto's peaceful life while still serving as an Order member. His weapon of choice is a multipurpose tool with various types of blades, and is also highly skilled at disguising himself as other people.


 * Shishiba (神々廻)
 * A member of the Order. He is cynical, strict, and hates onions with a murderous passion, but cares deeply for his fellow Order members, especially his mentee Osaragi. His highly professional nature often clashes with his peers' casual attitudes. His weapon of choice is a hammer.


 * Osaragi (大佛)
 * A member of the Order who only recently joined. Shishiba serves as a sort of mentor to her. She is childish, mischievous, often fretful, and rather gullible, but ruthless as a killer. She has a great love for food, especially snacks. Her weapon of choice is a large circular saw.


 * Hyo (豹)
 * A member of the Order. He is harsh and highly intimidating, but cares for the safety of others above all else; Nagumo enjoys antagonizing him due to this tsundere nature. He has incredible physical strength.


 * Takamura (篁)
 * A legendary, almost mythical member of the Order. He is elderly, seems to be senile, and constantly murmurs inaudibly under his breath, but is terrifyingly strong, being able to slice through nearly anything. His weapon of choice is a katana.


 * Kanaguri (京)
 * A member of the Order who secretly works for X. He is an eccentric movie director famous for movies about assassins; his passion is so great he will unhesitatingly kill anyone who insults movies. He has no particular loyalty towards X, only following him so he may create a movie about a battle between X and the JAA, with no care as to who wins. His weapon of choice is a bladed clapperboard and a heat-ray camera, which he also uses to help visualize his fighting as action choreography.


 * Kamihate (上終)
 * A member of the Order, who is recognized as the greatest sniper in JAA history. Extremely unsociable and preferring not to interact with associates face-to-face, Kamihate is a shut-in, whose face not even the other Order members have seen. When forced to collaborate, Kamihate goes so far as to have a fellow Order member carry a hiragana chart on a paper so that, if the sniper wishes to say something, he can simply shoot at the corresponding characters from afar to formulate messages.


 * Oki (沖)
 * The current leader of the Order and a stickler for the rules, who was overseas for an unspecified assignment, until Uzuki's assault on the JCC museum. Oki is a middle-aged-looking man with hollow cheeks, angular full-rimmed glasses, and long hair tied into two ponytails.


 * Torres (トーレス)
 * Torres is a dangerous elderly foreign assassin with great durability and an extreme gambling addiction, who gets recruited by Oki to fill in the empty spots of the Order.


 * Tanabata (七夕)
 * Tanabata is a young and obsessive assassin who turns his kills into songs to amuse himself, while playing the guitar, who gets recruited by Oki to fill in the empty spots of the Order.


 * Kindaka (キンダカ)
 * The co-founder of the Order alongside Satoru Yotsumura, who usually handled the disposal of problem students from the JCC. After Sakamoto, Rion, Nagumo and Uzuki are sent his way, he is impressed by their skills and recruits them for a special mission, during which Uzuki reveals himself as the enemy and puts him in a coma.

Students / Trainees

 * Akira Akao (赤尾 晶)
 * A very timid and anxious girl who befriends Sakamoto during the JCC entrance exam. She is good at housework, adverse to violence, and seemingly has no instincts as an assassin, but in truth, has great speed and reflexes, and seems to visualize a "path" she can follow to kill an opponent. She is the niece of Rion Akao, who apparently also saw the "path". She joins the JCC for information on Rion's whereabouts, and joins with Sakamoto, Shin, and Natsuki to locate the student database.


 * Natsuki Seba (勢羽 夏生)
 * A sarcastic, dry, and rather blunt student in the research department who temporarily worked for Kashima as an enforcer. He is the older brother of Mafuyu. Natsuki is known amongst his peers as a prodigious weapons maker, and has created countless inventions and prototypes of varying success. He and Shin get on each other's nerves, but work surprisingly well together, and ally to locate the student database. Natsuki's fighting skills are only average, but he utilizes a suit he created that grants invisibility to anything it covers, making him a tricky opponent.


 * Mafuyu Seba (勢羽 真冬)
 * A germaphobic, easily-agitated 14-year-old boy who aspires to be an assassin and participates in the JCC entrance exam. Despite his age, he is highly skilled and ruthless, remaining calm during battle. He is the younger brother of Natsuki. His weapons of choice are blades built into his boots, as he hates getting his hands dirty.


 * Nao Toramaru (虎丸 尚)
 * A cheery girl who is an obsessive fan of Sakamoto and participates in the JCC entrance exam. Her obsession is so great, she even views Sakamoto as a godlike figure, and targets Shin when she realizes he admires Sakamoto as well, though not realizing their connection. Her weapon of choice is a gun/axe hybrid.


 * Joichiro Kaji (加耳 丈一郎)
 * An incredibly shy boy who participates in the JCC entrance exam. He has highly sensitive hearing, able to pick out distinct, faint sounds even amongst static.


 * Amane Yotsumura (四ツ村 周)
 * An impassive and cynical student in the assassination department. Despite his outwardly cold personality, he is rather sincere, willing to apologize when he is mistaken, and gets along very well with his peers. He is the son of Yotsumura and Byodo's grandson, who he loathes for killing his mother. Amane collaborates with Uzuki to bring down the JAA and have the opportunity to kill Yotsumura, but turns against him when his fellow students are caught in the conflict. His weapon of choice is a bladed, four-sectioned staff, and is also highly perceptive. He also inherited his grandfather's superhuman memory, although it is not as accurate as his.


 * Jay Erk/Kill Baby

 * The janitor at the JCC, Yotsumura's father-in-law, and Amane's grandfather. Unlike Amane, he does not desire revenge against Yotsumura, and is very close with Amane and cares for Amane's well-being. He is a capable assassin, but his greatest asset is his superhuman memory, able to remember every detail about every student who attended the JCC after him, earning him the nickname "Database".


 * Etsuko Satoda (里田 悦子)
 * More often referred to simply as "Satoda-sensei". Along with her longtime friend and classmate Byodo, she has been at the JCC the longest as an instructor, even teaching during Sakamoto's time there. Though Satoda is skilled enough to earn an invitation to join the Order, she turned it down, deciding that fostering and protecting her students is more important. Though retired, she is an aikido master, specializing in redirecting and nullifying attacks.


 * Rion Akao (赤尾 リオン)
 * An incredibly skilled assassin and a classmate of Sakamoto in the JCC, along with Nagumo. She seems to have the unique ability to see "paths" to follow to kill opponents, something her niece Akira can do as well.

He is cold and determined when trying to accomplish his mission, but very caring and friendly towards his subordinates. He has met Sakamoto in the past, who is the only one who has injured him. Kei is revealed to have abilities to develop split personality disorder that was caused by his trauma of seeing his closest friends died, such as his trauma on the death of Rion Akao cause to develop her persona, and the death of Haruma at the hands of Takamura cause to develop Takamura's.
