Part I

Rookie King Tournament: First Rounder Arc


Kobashi meets Ippo for the first time.

Kobashi entered in the East Japan Rookie King Tournament. His first opponent was Koichi Takahashi, defeating him by decision, moving him to the second round. His second opponent was Yoshida Mitsuo, one of the four seeds of the tournament. Kobashi defeats Yoshida with a decision and moves on to the third round, with his opponent being Makunouchi Ippo.

Kobashi goes to the Kamogawa Boxing Gym and watches Ippo training through the window, gathering notes. When Ippo leaves the gym, Kobashi runs away, dropping his notebook. He is then met by Ippo, who gives the notebook back to him. Before walking away, Kobashi explains to Ippo that while he doesn't have an outstanding punch or technique, those aren't the only thing that matter in boxing.

At the Ōtaki Boxing Gym, after having a spar, his trainer, Yasuda, cheers him up by telling him of the boxer Maxie "Slapsie" Rosenbloom who achieved 222 victories, but only won 19 by KO. Yasuda decides to treat Kobashi to soba as the two discuss his upcoming fight. Though, Kobashi is extremely nervous, he still has the confidence that he can win.


Kobashi connecting his first clean hit.

At the Kourakuen Hall's dressing room on the day of the match, Kobashi has an image in his head on how the fight will go, which is to have Ippo defeated easily. When the match begins, Kobashi quickly uses the Cross Arm Block and defensive motions, successfully blocking and avoiding Ippo's aggression. After Kobashi clinches, he throws jabs, hitting Ippo multiple times until Kobashi is pushed to the corner. However, before Ippo could attack, round one ends. In round two, Kobashi's plan becomes effective when Ippo becomes visibly exhausted. Kobashi further blocks and reads Ippo's combinations in round three, making his opponent more exhausted.

In the fourth round, Kobashi throws a powerful straight to Ippo's jaw, who in turn buckled from the unguarded attack. Kobashi, surprised at his own strength, resolved to finish the match with his own two fists, wishing for a KO victory more than ever. However Kobashi gets knocked out by Ippo in the last seconds of the match when he missed an attack, losing the match.

Kobashi, in the resting room, apologises to Yasuda for losing. In turn, Yasuda informs him that the one straight he landed was a great punch, and that Kobashi should start over again.

First Step Arc

Kobashi made a comeback in the Junior Featherweight division, where he became the 2nd seed. After Sanada Kazuki relinquished his belt to move up a class, Kobashi faced the first seed of the Junior Featherweight class, Hayami Ryūichi, for the vacant title. As the fight reaches it's climax, Hayami appears to have the lead in the points, and he has the obvious support of the audience, which is mostly comprised of young women. When the round ends, Hayami states he will not get careless, as he learned that lesson the hard way in the past. On the other corner, Kobashi says he does not care about the points, and wants to have the feeling he first experienced against Ippo.

The next round starts and Hayami takes the initiative but Kobashi soon returns. They go back and forward with each of them critically hurting the other and remembering their matches against Ippo, but they soon stop dodging, and concentrate only on hurting each other. Kobashi suddenly lands a punch to the jaw, sending Hayami to the floor and causing his corner to throw in the towel while he is unconscious.

While muscular and average in height, Kobashi is known for his weak and fragile body despite being in the featherweight division. His appearance is largely without special quirks, with a pale skin tone and short black hair. His eyebrows are of average thickness, matching the colour of his dark eyes.


Kobashi possesses an openly shy, mellow attitude with a lacking in self-confidence. This attitude is the result of Kobashi possessing relatively weak punches, being forced to adopt an outboxing style that many consider to be "cowardly", and he is regularly mocked by his peers for lacking any punching power. He is shown to be extremely uncomfortable around most people and displays a want to avoid any social interaction with others. However Kobashi has a (typically dormant) fighting spirit that occasionally emerges during matches, as seen in his match against Ippo where he, despite his fragile body, wanted to win against Ippo with a KO because he "felt it in his fist". After his loss, Kobashi shows a very encouraging personality towards Ippo, whom he requests to win in the tournament for the sake of both he and Ippo's previous opponents.



Kobashi's fighting stance.

Kobashi's boxing style is considered that of a lower key compared to other characters in the series. Not sharing the great skill of his fellow featherweight boxers, Kobashi usually relies on dull tactics such as simple jabs, footwork, clinches and a strong cross-arm block to achieve victory through points, rendering his style extremely defensive and absent of any blows with a knockout intent. Kobashi's boxing stance has his left arm outstretched, positioning himself to be a difficult target and keeping his opponent at the perfect distance for scoring. While usually lacking hugely in power, Kobashi has shown some hidden potential for great strength in his matches against Ippo and Hayami.



Kobashi's physique is generally inferior. In particular, he lacks a strong punch - a weakness brought up by his sparring partners and coach. Consequently, his fighting style is more defense-orientated and focuses on winning by points as opposed to by KO.

Kobashi's major weakness, as displayed in both his fight against Ippo and Hayami, is his innate desire to win by knockout, as his drive to land clean hits against his opponent clouds his focus and results in him dropping his guard. After a successful one-two against Ippo, Kobashi abandoned his game plan of winning by points and attempts to fight toe-to-toe with him, ultimately losing against the heavy hitter. This is also evident in his fight against Hayami; despite ultimately winning the match by K.O, Kobashi still took several clean hits due to his recklessness.



  • He shares the same name with real-life professional wrestler and promotional star Kobashi Kenta.
