Characteristics Edit

Appearance Edit

Banba is described as a tall, lean man usually dawning a white sweater with old jeans. The novels describe him as having messy, unkempt, black hair and brown eyes however, illustrations show him with dark brown hair. Despite his noted height, he is usually hunched over.

Personality Edit

Banba has a gentle and laid-back personality, usually not caring for his appearance or the cleanliness of his residence, much to his roommate's annoyance. He is usually patient and understanding in most scenarios, but when it comes to baseball he can be overbearing, especially to the novice of their team, Xianming Lin.

Background Edit

With his mother dying shortly after giving birth to him, Zenji Banba was raised single-handedly by his adoptive father, Kazuyoshi Banba. Banba had a normal and peaceful childhood until one day during high school he arrived home to find an unknown man stab his father. Having just came back from his baseball club activities, Banba attempts to attack the intruder with a baseball bat on hand only for it to be taken from him and used on him instead. He loses consciousness, and by the time he regains consciousness another man wearing a Niwaka mask knocks out his attacker before calling the ambulance to get Banba medical treatment.

Banba wakes up later and is informed that while he managed to survive almost certain death his father did not pull through. He asks one of the police detectives that frequently visited him for questioning, Shigematsu, about the man wearing the Niwaka mask he saw. Determined to find the man, Banba drops out of school and starts working at a host club in the Nakasu area, where the man in question is noted to shown up on occasion.

History Edit

Mayor Harada Scandal Arc Edit

Banba meets with Shigematsu in Kego Park, who informs him of the recent death of his colleague, Takeda. While it was officially ruled a suicide, the two conclude he was most likely killed for investigating Mayor Harada and his connections. After Shigematsu gives Banba a photo left behind by Takeda, he asks him to figure out the circumstances behind the detective's death. The photo shows the Mayor in the company of two unknown men and a woman. Suspecting the woman in the photo to be a killer, Banba decides to consult with the informant, Enokida.

He learns that the woman with the mayor is Reiko Asakura, an assassin and former Murder, Inc. employee, who specializes in killing people with poison. However, Banba points out that it is unlikely she was responsible for Takeda's death, and asks Enokida if he can dig up any information on anyone who specializes in strangulation. With this, Enokida swiftly pulls information on another former Murder, Inc. employee, Hisashi Ivanov. Before Banba leaves, Enokida gives him a GPS-equipped redback spider model listening device.

On his way home, Banba runs into Yamato and ends up questioning him about the people pictured with the mayor. Yamato recognizes one of the men in the photo as Takashi, an employee of a club called Miroir, so Banba heads there in an attempt to find out more. However, when questioned, the manager claims to not even remember if the mayor had ever been there. Banba is confident he is lying and leaves knowing he succeeded in confirming their relations and catching their attention.

After updating Shigematsu on the situation, Banba returns home to find himself being greeted by an unexpected visitor - a hitman named Xianming Lin, who came in order to protect him from other hitmen the Kakyu Association will send. He explains that while he had originally been sent to kill Banba, protecting him was his way of getting back at his employer over a disagreement. Since Banba decides to humor Lin by staying inside and out of harm's way, he gives Lin the task of going out to buy some mentaiko. After returning to the office, the two of them eat some tonkotsu ramen and watch a baseball match.

The following morning, Banba leaves the office while Lin is sleeping and meets up with Enokida in order to find out more about Lin. After retrieving this information, he returns home to find Lin, who has tied up a killer dispatched by the Kakyuu Group. After letting him go, Banba offers Lin money for information. When Lin agrees, Banba interrogates him and learns that the other man in the photo with the mayor is Zhang. Lin takes the money and leaves. Later that day, Banba tracks down Lin with the redback spider model listening device he put on him earlier and arrives at the Kakyu office shortly after Lin kills Ivanov. Then after retrieving Ivanov's cell phone, Banba attaches the listening device to Ivanov's collar. He then leaves with Lin, who, due to his wounds, loses consciousness. Banba takes him back to his office.

Not long after Lin regains consciousness, Shigematsu arrives at Banba's office with information about the man suspected of murdering Qiaomei Lin, Takuya Itou (Saitoh). But having not really learned anything new and agreeing that Itou had nothing to do with it, Banba accepts Lin's request to locate Qiaomei's killer and asks for five years worth of mentaiko as payment. Enokida arrives to share his findings into the killers hired by the mayor. He shows Banba and Lin the footage from the surveillance cameras at the hotel Takuya Itou was staying at, revealing he was set up by Reiko and Munakata. Enokida plays them the recording from the bug Banba planted on Ivanov's body and hear of Yusuke Harada, the likely culprit of Qiaomei's murder. Lin formulates a plan to have himself be sold to Yusuke as a woman trafficked by the Kakyu Association in order to kill him and asks for Banba's and Enokida's help.

Later that evening Banba pays a visit to Genzo, who is a killer agent. Genzo tells him that a request to kill both him and Lin came in from the Kakyu Association, who have hired the Niwaka Samurai to carry out the job. Banba accepts the job, regardless that he is both the hitman and person wanted dead, and heads to Saeki's cosmetic clinic, where he makes an offer to buy a body which had just been dropped off by Jiro. After Banba relays the events to Jiro and hears about Jiro's own case, realizing they correlated, Banba asks him to avenge Qiaomei's rape and death and lets him know that Yusuke is the culprit. Later that day, Banba, as the Niwaka Samurai, has already been to the Kakyu Association office to accept his assignment from Zhang.

As planned, Banba meets with Lin, disguised as a Kakyu Association broker. He gives Lin a redback spider model device and a microphone to call him in case of trouble before having Lin hide in a suitcase. Banba goes to the meeting and the suitcase with Lin inside is transferred to a car trunk. When Lin is faced with Zhang and realizes he has been set up by Enokida, he calls Banba for help through the microphone. Banba is called by a distressed Lin for backup but ignores it and continues to keep up with his Niwaka Samurai persona. He is ordered by Zhang to behead Lin but instead cuts down Zhang and his men, including Shinohara and Munakata. After he releases Lin from his bounds, he removes his mask and reveals his identity to Lin. Shortly after, Shigematsu arrives to clean up the crime scene and allows Banba and Lin to leave to confront Yusuke.

They go to Yusuke's apartment building where they meet with Jiro and Saitoh. Banba is wearing the Niwaka Samurai mask again. He waits for Reiko to call Munakata's phone, which he had retrieved earlier, and introduces himself as the Niwaka Samurai and announces he is coming for Yusuke. When she rushes out of the door to escape, they capture her and knock her unconscious before Banba and Lin head inside to look for Yusuke. Yusuke comes out of his hiding and ambushes them with a gun, but before he could shoot at them Saitoh throws a baseball at him and incapacitates him. They take Yusuke and prepare to take him to a warehouse to carry out Qiaomei's revenge, but before they leave Banba invites Saitoh to join their grass-lot baseball team, the Hakata Tonkotsu Ramens.

Some time later, Banba and Lin go to a warehouse where Yusuke is kept bound to a chair. Banba interrogates Yusuke while Jiro records his confession, which they send to Enokida later so he could broadcast the confession to overthrow the mayor. Banba and Lin leave before the avengers start torturing Yusuke.

A few days later, Banba asks Lin where he would go now and upon hearing he has no place to go, offers him a place to stay at his office. Around this time, he also convinces Lin to join their baseball team, despite Lin not knowing anything about baseball.

Niwaka Samurai Impersonator Arc Edit

A half year passes, and Banba begins to wrap up his remaining jobs before he goes on hiatus for the Yamakasa event he annually participates in. He receives a client, Kumiko, who tasks him to find out what her husband's late night activities are and to confirm the partner(s) he is cheating with. Banba calls Yamato up for a favor, asking him to recommend Lin to work as a hostess at the club Kumiko's husband frequents. While on Lin's first night, he goes in as a guest to check up on Lin's progress as well as Sayuri's, whom he had requested to kill the leader of the Kakyu Association from. Afterwards, he leaves the club and goes to complete an assignment as the Niwaka Samurai.

He finds his target, Yasakuni Shindou, as he makes his escape through the hotel garage. After striking down his target, he stumbles across Lin, who had been hired as his bodyguard. Lin goes to attack him out of frustration but slips and falls, not paying attention to his surroundings. Banba offers a hand to help him stand up (which the other refuses), and the two head over to Genzo's ramen shop where Lin informs him on how the Kakyu Association is hunting the Niwaka Samurai down and is looking into hiring the infamous hitman G.G. Banba is taken aback when he hears this and turns to Genzo questioningly but Genzo confirms G.G is retired, indicating this G.G the Kakyu Association were looking for is a fake. Banba dismisses the issue and informs Genzo he would not be taking any more jobs as the Niwaka Samurai until the Yamakasa event is over. Beginning the next day, Banba only focuses on preparing for the Yamakasa and leaves Lin to handle Kumiko's case.

On the day of the Yamakasa event, Banba is approached by Genzo who delivers the news Lin took a job as the Niwaka Samurai in his place and has been presumably killed. He shows the picture of the fake Lin's body, and initially believing it Banba decides to leave the Yamakasa to meet with the person who has Lin's body where he encounters Shunsuke Saruwatari. Banba insists to see the body and when he does, he immediately recognizes it is a fake. Knowing this, Banba turns to leave and head back to the Yamakasa event, but Saruwatari instigates him into a fight. They exchange a few blows until the Kakyu Association show up and interrupt the fight. Surrounded, Banba surrenders and allows himself to be taken to their hideout.

Banba is brought to the torture room at the Kakyu Association's office where he had struck down Zhang and Munakata's group the year before. As he waits for his fate, Saruwatari busts into the hideout and kills the guards, letting him free. Saruwatari proposes a temporary truce, wanting the right to fight with the Niwaka Samurai. The two team up and fight the hoards of men attacking them, retreating to the rooftops for a standoff. Once the threat is gone, Saruwatari and Banba resume their match. During the fight, Banba successfully hits back Saruwatari's shuriken, causing him to stumble off the rooftop. Banba manages to catch him and save his life. Banba states he won the round and they can fight again some other time.

After Saruwatari (reluctantly) agrees and takes off, Lin arrives at the rooftop and finds Banba. But a surviving member of the Kakyu Association is unnoticed by Banba, who takes a shot at him. Lin manages to warn Banba in time to avoid the attack, and the two team up to take the man down. Afterwards, Banba laments to Lin on how he missed the Yamakasa event, to which Lin offers to treat him to ramen to cheer him up.

A week later, the Tonkotsu Nine face off a grass-lot baseball team from Kitakyushu and struggle against their underhand pitcher. When Banba goes up to bat and is narrowly hit by the pitcher's poor throw, he loses his temper and starts arguing with the pitcher. The situation escalates, resulting in the two to exchange blows, knocking their hats off and revealing their faces to each other. Banba immediately recognizes the pitcher's face as Shunsuke Saruwatari, the Submarine Ninja. With this meeting, Banba and Saruwatari's rivalry only strengthens as both hitmen and baseball players.
