The Ha-Ha Brothers (ハァハァ三兄弟 Ha-Ha Sankyōdai, lit. "Ha-Ha Three Brothers") is a trio of delinquents, currently affiliated with the Deimon Devil Bats.


Sena Kobayakawa has been their gopher since kindergarten and at their first day at Deimon High, they order him to buy items for them. In the anime, they had only met him in class that morning. After Sena made a final dash and jumped into the MRT carriage, Yoichi Hiruma, who spotted Sena's talent for running and dodging, beat up the brothers and took pictures of them naked. Hiruma keeps the negatives of the photos and extorts them into playing and later joining the team by threatening to reveal the photos to everyone. During the Zokugaku Chameleons exhibition match, they were searching for the negatives of the pictures when Kurita stumbled upon them. Kurita wrongly assumed they were intending to join the club as linemen. Later, because of the appearance of Kurita's apprentice, Komusubi (and his constantly looking down upon the brothers), they competed with him at the Tokyo Tower and managed to pass Hiruma's qualification test (fittingly called the Tower of Hell). The three decided to quit the team later and forget about the negatives of their pictures, regardless of what Hiruma did. However, after being beaten up by Banba of the Taiyo Sphinx, they changed their minds and set out to become great linemen. Koji and Shozo were considered as trash by the editor of a sports magazine after their match against Taiyo Sphinx, but later proved themselves as linesmen during the games against NASA Aliens. During the game against the Americans, they also learned a new maneuver called the Sweep. It was here that Kazuki shows his respect for Eyeshield by promising to open a line for him to get through. During the Death March, they learn the proper method of pushing off with their entire body, rather than just their arms. In the anime, even Otawara of the White Knights found it difficult to hold them back.

Ha-Ha Brothers looking clueless.

The Ha-Ha Brothers have a running rivalry with Komusubi, who always shows them up in tests of strength and determination. Hiruma approves of this war of the linemen, which drives the Ha-Ha Brothers to become better players. During the Death March training in America, two of the Hah Brothers, Koji and Shozo were about to abandon the team due to the harsh training and lack of determination, but they changed their minds once they learned that Hiruma and Kurita will no longer be able to play after their second fall season. This would be their final chance. Kazuki also pointed out that they earned more respect as linemen rather than as useless punks. It is also fair to note that their background as punks has come in rather handy in several games, where they've relied more on their streetfighting skills than actual lineman skills, like against Zokugaku and Seibu.

In the game versus Bando, when they are introduced individually, Machine Gun Sanada describes Kazuki as having the best technique, Koji the best speed, and Shozo the most power. This is another sign of their branching out as individuals.

List of The Ha-Ha Brothers

Kazuki Jumonji

(十文字 一輝 Jūmonji Kazuki) Kazuki is the apparent leader of the group. In some of the episodes including the NASA Aliens game and the Death March, we see him as a leader who urges the other two to follow. He sports an X-shaped scar on his right cheek, which was originally supposed to be used to get Kurita arrested. He is also the only one of the three to figure out that Sena was actually Eyeshield 21. He seems to be the most thoughtful (in a sort of positive way). He always seems to keep the three-some (includes him) together and is considered the "eldest brother" of the three. He gets fired up a lot. He is also the only one so far of the three to score a touchdown, and probably the only one in Deimon Devilbats who has scored touchdowns on defense aside from Sena.

Koji Kuroki

Koji Kuroki

[Koji Kuroki](黒木 浩二 Kuroki Kōji) Koji sports dark hair of medium-length with noticeably longer eyelashes than the other two. He seems to be the most violent, and his usual weapon is his metal bat. He suggests that his specialty is to "Strike only once from behind," and he has claimed himself to be a coward more than once. When playing defense, Koji can sometimes play Linebacker. The other two stick to Defensive Line. He seems to be a prodigy at games, whether it be tossing hoops or an arcade game. (In the first book end-of-the-book character introduction, he is shown to be firing a Kikôha as he yells "HUH-DOE-KEN!!!") In the arcade when Deimon does their final prep work for facing Seibu the first time, Koji is shown to be furiously button-mashing, and a player comments that he is unexpectedly good at video games. Out of the three, Koji is the most hot-headed, and willing to fall back on his streetfighting skills when his lineman skills fail him. Later, as he and the others become more distinguished as individuals, Hiruma gives him his own nickname, 'fish mouth'.

Shozo Togano

(戸叶 庄三 Toganō Shōzō) Has long spiky blonde hair, and constantly wears orange-tinted sunglasses. Can

Shozo Togano

usually be seen reading manga. He seems to be the quietest of the three. Likes Jump, but puts it aside for a while when going to the United States, saying "Sigh, I guess American comics are alright." Compared to the others, Shozo is fairly laid-back, preferring to read his manga, often just going along with what Kazuki and Koji want.



  • In each of the boy's names are the kanji for one (Kazuki), two (Koji), and three (Shozo). Their first names imply the number of sons born in the family. This means that Kazuki is the only child, Koji is the second son, and Shozo is the youngest son of three.
  • Early in the manga, Hiruma refers to them as the Ha-Ha Brothers seemingly because he believes (or wants them to think he believes so, just to aggravate them) that they are actual brothers
  • At first, when they entered the team for the first time (due to the blackmailing by Hiruma), they only being given single locker in the team restroom for all of them. However, as they grow stronger and more determined, they finally had more lockers, one locker for every single one of them.
  • In the manga, all three of them drink and smoke. After the Taiyo Sphinx game, Kazuki quit smoking when he read the 'Football Monthly' article, to focus on his game. Musashi persuaded Koji and Shozo to quit as well (noting that "Real athletes don't smoke. Smokers lose their breath too quickly.") by swearing off smoking himself. Whether they still drink or not is unknown.
  • Though it is not certain why Kazuki is actually very popular with girls, mentioned constantly by Koji and Shozo ("Dammit! Even though we were never confessed too..." [Koji] "Though I wonder how many times it happened to Kazuki." [Shozo] "Ah?" [Kazuki]).
  • In the anime, Koji and Shozo actually do abandon the team during the Death March unconvinced by Doburoku's reasonings. Kazuki runs after them, stunned when Koji revealed his knowledge of the negative article against him and Shozo, furthering his reasons for leaving. Kazuki punches the two, saying that they can change their reputation like Sena did. After a long fistfight, they agree to return together not for the team's sake but to prove their self-worth to others.
  • Another shtick they do is finish each other's lines or thoughts one by one based on age. The order would then be Shozo (the youngest), Kazuki (the middle), and Koji (the oldest). (i.e.: Shozo: "So that would mean..."; Kazuki: "what we have to do is..."; Koji: "Yeah. We have to believe in our teammates' strengths more."). It should be noted that when this occurs, Koji often has the longest quote of the three. In the manga, they say one thought in unison.
  • Kazuki and Shozo have unique nicknames used only by the trio: "Kazu" and "Toga".
  • Koji's seiyuu also voices Cerberus and Shozo's seiyuu also voices Unsui.
  • All three have taken to Hiruma's habit of kicking a teammate in the rear, (for them it's simultaneous), without saying anything, whenever that teammate does something spectacular.
  • In the recent manga, the Ha?! shtick trio has been added into the fourth one by their lineman party Daikichi Komusubi, ending with "Han!" (Ex. Shozo: HA?! Kazuki: HAA?!! Koji: HAAA?!!! Komusubi: HAN!).

Techniques and Strategies

  • Screen Pass - They intentionally let their opponents break through the line, then shift over to make two-on-one blocks on the other side of the line of scrimmage. This creates a wide area for Eyeshield to go through once Hiruma laterals the ball to him.
  • Delinquent Death Blow - Also known as the Juvenile Deliquent Murder Method, the Scumbag Scuffle and Rascal Killing. The Hah Brothers practiced the technique with the Zokugaku Chameleons. The method involves grabbing the opposing lineman by the sleeve, taking a diagonal step up, then slamming the opponent face-first into the turf by using the opponent's driving force against himself (though technically, that move should be considered as Unnecessary Roughness/Unsportsmanlike Conduct). This is especially useful in getting past larger linemen in order to sack the quarterback. Kazuki uses this move the most often, while it is rarely, if ever, executed by Shozo and Koji.
  • Sweeper - A method in which linemen form a protective barrier in front of Eyeshield, thereby clearing a path for him in a diagonal direction. After the Death March, they are able to clear a very wide passage for him to go through.
  • Hip Explosion - During the Death March, the Ha-Ha Brothers learned the proper method of pushing out with their entire bodies, rather than just their arms. By thrusting out their hips, they can deliver more force against opposing linemen. Koji in particular exercises this move against the seemingly unbeatable Aoyanagi in the game against Amino.
  • Ha Ha Triple Attack - Shown in the anime first, a three-on-one tackle with each Ha Ha brother using their own strengths as a means of gradually nullifying quick and sturdy opponents. Koji leads, first using his speed to cancel the runner's sprint. Shozo then uses his power to beat the force of the runner's counter. While the opponent is distracted, Kazuki uses his techniques (often being the Juvenile Delinquent Murder Method) to finish the move. Alternate versions include tackling from three different directions at once or tossing their opponents into the air. Recently, in the manga, this was shown when they saved the ball from Teikoku's possession after failed Christ Cross. In here, Koji and Shozou hold Reisuke Aki from holding/ securing the ball, while Kazuki batted the ball down. Kazuki's father seems to hold a different opinion of the gang as he watches the technique.
