Kyōsuke Imai (今井 京介, Imai Kyōsuke) is a semi-recurring character in Hajime no Ippo

He is a featherweight professional boxer and the current Japanese Boxing Commission featherweight champion affiliated with the Otowa Boxing Gym. He is proclaimed the eternal rival of boxing genius Itagaki Manabu, and is known for being a very talented hard puncher capable of holding his own against Makunouchi Ippo twice in spars, as well being a very huge fan of his and one of his former goals.

His surname is Imai. In Japan, surnames are listed before given names.



Imai winning against Itagaki in the Inter-High.

Imai's father owned a big company. Because of that, he took up boxing so that he would not be seen as a little rich boy[1] and he didn't want to be the heir.

In his high school days, Imai was an inter-high boxing champion for two years in a row. He defeated his rival Itagaki Manabu three times, all times by knockout.[2] While fighting Itagaki, he noticed Itagaki Nanako cheering from afar and became attracted to her. He was shocked when he found out it was his rival's sister.[3]

He later went into professional boxing and grew to idolise Makunouchi Ippo. Despite his idolisation of Ippo, Imai chose to join any gym but the Kamogawa Boxing Gym in hopes to one day be able to fight Ippo in the ring, ultimately going to the Otowa Boxing Gym.

Imai and his coach visited the Kamogawa gym to have a sparring match with Makunouchi Ippo. After introducing himself and telling Ippo how much he looked up to him, they got in the ring to spar. The spar lasted three rounds with Imai having no downs and was giving Ippo a hard time. As a result of the spar, Imai believed Ippo to be strong and a good goal.

When Itagaki Manabu arrived at the gym and learned how Ippo was pushed in a spar by Imai, he was hostile toward Imai. Imai attempted to greet Itagaki, but Itagaki turned him down. Disappointed that Itagaki turned him down, Imai claimed that he will aim at becoming pro and will take the shortest path to Ippo's title. Imai then left the gym without a word after Itagaki told him that he will stop him from doing that.

Imai then got into the ring when Ippo accepted the spar. Imai gave him a hard time in the two round spar, impressing his coach, who believed Ippo would have fallen if they used 8-ounce gloves despite Imai's uncertainty.

After watching Makino Fumito's match in the East Japan Rookie King Tournament quarter-finals, Imai ran into Makino outside the Kōrakuen Hall as he was criticising Itagaki for bringing his "girlfriend" with him to watch the match. Imai corrected Makino by revealing Itagaki's "girlfriend" as his younger sister Itagaki Nanako. As tension rose between the three, Ippo stepped in to stop them. Imai deemed Makino as a mad dog and wondered if Itagaki was going to win and make it to the finals, which Itagaki then told him the same thing. Itagaki wanted to know why Imai knew who his sister was. Imai explained that he always heard her cheering for Itagaki when they fought in the past.

Itagaki and Imai meeting after Ippo's match

After Ippo defeated Karasawa Takuzō, Imai ran into Itagaki while waiting for Aoki. Imai told him that he was there because he intended to fight Ippo in the future, where the winner of the Rookie King Tournament will be ranked 10th. He will have the right to challenge Ippo, and he planned on taking the shortest route to the title by challenging Ippo. Itagaki told him that he will stop him, but Imai told him based on Ippo's match, it is a good reference for their fight against Itagaki. Now embarrassed, Itagaki agreed that it the same for him, where Imai will be the one on the mat. Imai thought that Itagaki didn't look well with his cheek bones showing, he thought Itagaki might have failed his weight control. He asked Itagaki what he planned to do if he won, or his future plans are with Ippo, but Itagaki didn't answer. Imai told him that he wanted to test his own power and fight a strong champion, which was why he picked a different gym from Ippo. He thought Itagaki picked the same gym to be under Ippo because he didn't want to fight him. He believed they were looking at two different things, where the difference between them will come out in their match. He wanted to make a bet with Itagaki, where he will do anything Itagaki wants if he won, but if Imai won, Itagaki's got to introduce him to his sister. Itagaki grabbed Imai intending to fight him after he heard that, and was angry for bring such a thing into their match. Imai was serious about it. As Itagaki was about to throw a punch, a mummified Aoki appeared to stop it, and told them not to fight. Itagaki ran to check Aoki after he saw his condition. While leaving and laughing, he thought Itagaki gym was interesting, and told Itagaki to remember what he said.

A few days prior to his match with Itagaki, Imai was still preparing for it. His coach told him that Maezono Makoto had already won the West Japan Rookie King Tournament, and he might be a troublesome opponent because he was a southpaw. Imai told him they aren't done with the East Japan Rookie King Tournament yet to focus on his next opponent. However his coached believed Imai will win since he defeated Itagaki 3 times in the past, where he shouldn't be neverous over it. Imai continued to train, and he thought he never defeated Itagaki easily. He believed Itagaki increased his speed even more, and he didn't think his punches will slow him down. His punches need to be sharper and stronger. At the weigh in, Itagaki and Imai both past fine. Imai told Itagaki he thought Itagaki would have failed his weight control, but Itagaki looked in good condition. Itagaki told him that his sister didn't want to go out with him, but Imai forgot about their previous bet of late since he was focused on winning. Itagaki was the same.

While Imai waiting for Itagaki to arrive to the ring, his coach was complaining about it to the referee and the crowd started to join him. After waiting more, Itagaki ran out and jumped over the top ropes into the ring for a flashy entrance. Imai was concentration on how he would fight still. As the match started, Imai charged at Itagaki. While outboxing, Itagaki used his legs for distance, he thrown some lefts and Imai kept chasing him.

The match turned into a power vs speed match up with Itagaki dodging using his speed to land his Hedgehog while Imai kept throwing strong punches in order to hit him. Imai came close a few times, but Itagaki was able to barely dodge them. The distance between them decreased as the match went on, and Itagaki started to feel Imai's pressure.

He over heard Ippo mention that he thought Itagaki and him were good friends, which Itagaki disagreed with him until Ippo told him about the end of their match, where it looked like Imai was holding him up like he was praising him or had a bond between them. Itagaki told Ippo that he must be joking since he considered Imai his enemy when Imai finally enter the room. Imai wanted Ippo to take those words back, since he also thought of Itagaki has his enemy too. Itagaki complained about Imai being there while looking healthy while he was hospitalized. Imai told him just wanted to drop off some video of his next opponent since he didn't need them. He added that the boxer who was expect to win it, lost while someone knocked him around like he was a kid. He warned Itagaki should watch the videos when he leaves, even if he didn't want them. Itagaki remembered the bet that was made before the match, where he told Imai to do a Dogeza (where he kneeled down in front of him and apologized.) Just Imai was about to do it, Itagaki's sister entered the room creating a weird atmosphere. Imai told Itagaki that since he was still healthy right now, and Itagaki was in the hospital, he believed that meant he lost the battle but won the war between them. As he left, he told Itagaki the real conclusion between them will be the next time they face each other, until then they will postpone the promise.

A day later, Imai visited Itagaki against as he was getting checked out by Mashiba Kumi, where Itagaki didn't want to leave the hospital with Kumi watching over him. Imai doesn't like Itagaki being distracted by the nurses with is match coming up, but Itagaki didn't want to hear it even though Hoshi was strong.

Imai offered to help him, which was why he visited him every day. Itagaki's motivated and interested in leaving the hospital. As he was about to leave, Nanako noticed it and started yelling at them, and she wonder why Imai was there if he doesn't stop him from doing stupid stuff.

Imai Kyosuke - PS3 - 03

Imai's appearance.

Imai is a man with short black messy hair with strands of hair going over his forehead. His eye colour is black and he has large bushy eyebrows. His body is well-built for the featherweight class. His boxing attire consists of dark coloured boxing shorts with a giant "I" for "Imai" on his front left side and a giant letter "K" for "Kyōsuke" on his front right of his shorts.


An incredibly serious and respectful member of the Otowa Boxing Gym, Imai is shown to show great admiration towards fellow featherweight in-fighter Ippo. It is shown that he wishes to befriend Itagaki sincerely on one occasion, even going as far as calling him by his given name, but quickly recoils and turns harshly confident when the latter refuses his offer of friendship.

He has an unrequited love for Itagaki's younger sister Itagaki Nanako and comes from a rich family. It is mentioned that Imai's relatives strongly disapprove of his choice to become a boxer.

Boxing Abilities

Despite his youth, Imai has proven to be a very capable fighter, able to defeat Itagaki twice before they turned pro and hold his own against Ippo, then the Japanese champion. He has been compared to Ippo in terms of strength and style as a fellow in-fighter. He fights with an orthodox style, although he tends to make wide swings to scare off his opponents. His main weapons in the ring are his strength and stamina, which make him a powerful hard-punching boxer. According to Ippo, Imai's punching power is greater than Shimabukuro Iwao's, a boxer whose punches were comparable to his own.



Imai doesn't possess any footwork, which makes him easy to out-box. He does, however, compensate for this in his latest battle with Itagaki in which Imai cornered Itagaki.


Main Article: Imai Kyōsuke/Gallery


  • (About Itagaki) "Your puny punches won't stop me. [They're] weak weak weak weak WEAK!"[14]
  • (To Ippo about Miyata) "This isn't just a matter of trying hard. Just look at the stadium right now. This is a professional boxing match, and a title match on top of that. No one's cheering. No one's excited. The whole atmosphere is dead. Does a pro disappoint his paying fans? A pro's only job is to deliver what the fans come to see. At least that's what I think. "[15]


  • Imai mentions he admires Hamada Tsuyoshi when he first meets Ippo. Imai is probably modelled after him since they have a similar appearance and fighting style.
  • Although he and Itagaki Manabu purport to dislike each other, they still refer to each other by their first names, "Manabu" and "Kyōsuke".
  • Imai is the only boxer that hasn't been knocked down in the entire series even during his spar with Miyata.
  • Imai is a fan of Ippo, and he wishes to fight him, similar to Yamada Naomichi and Kojima Hisato.
