Ippo's High School and Pro DebutEdit

As usual school bullies, Umezawa along with his friends, Takemura and Matsuda catch up to fellow student Makunouchi Ippo one day after classes, begin beating him underneath a bridge. Trying to provoke a reaction from the submissive high-schooler, they are stopped by Takamura Mamoru, who scares them away by dodging their punches and stealing the buttons off of their school uniforms with his impressive footwork.

After learning of Ippo's becoming a pro boxer and then witnessing his second match against Fujiwara Yoshio, Umezawa makes numerous attempts to apologize for bullying him, but instead "forces" Ippo to let him and his gang be his fans.

All Japan Final Round: Makunouchi Ippo vs Sendou TakeshiEdit

On graduation day, Umezawa forces Ippo to take pictures with the gang and several other students to keep memories of their friendship. On the way home they come across the bridge from before, where Umezawa tries again to apologize to Ippo but before he can, Ippo innocently assumes he is trying to ask when the next match will be. Umezawa realizes that Ippo views him as a friend, and decides to let the past go.

Rookie King vs. Rookie King: Makunouchi Ippo vs Okita KeigoEdit


Umezawa working at the fishing boat.

After school, he finds employment as a salary man but soon quits his job in order to help out at the Makunouchi Fishing Boat when Ippo's mother is hospitalized. This situation leaves only Ippo to take care of things and ultimately forces him into an early retirement. Umezawa arrives during a typhoon to share with Ippo his dreams of writing a manga about him (Ippo). Knowing that he will not be able to do it if Ippo retires so soon, he helps Ippo out so he can continue boxing. After the first day he almost reluctantly quits on Ippo, but after seeing Ippo practicing his jabs, he decides to go through with it for his friend (he would later be thanked personally by Coach Kamogawa for this).

Throughout the following years Umezawa becomes more and more supportive of Ippo; he helped Ippo's mother design his new boxing shorts, once brought their teacher and classmates to a match, and even became involved with the production of Kamogawa Boxing Gym goods.

Sometime before Ippo's fight against Sawamura Ryuuhei, Umezawa wrote a one-shot manga about his experiences on the fishing boat to submit to a publisher. After letting Ippo read it (and after redoing a few pages that were accidentally torn up by Takamura and Aoki), he decided to retire from Makunouchi Fishing Boat in order to pursue his dream. During his farewell party, he tried to confess to Ippo's mother that he was the one who gave Ippo all those bruises during high school but was unable to finish because she had already figured it out, and told him to always hold his head up high without looking back with regrets.

Before leaving, he asked Ippo what he should tell people when asked how they know each other, but left before he could get an answer. Ippo used the fishing boat to chase after him and tell him that they know each other as "classmates, acquaintances, co-workers... but most importantly best friends", resulting in a tearful yet joyful goodbye.

Not long before Itagaki Manabu's Rookie King match against Imai Kyousuke, Ippo and Itagaki learned that Umezawa had gotten a job as an assistant to a professional manga artist and decided to pay him a visit. It was revealed that his one-shot debut manga, Ma Ippo Get You!, had won the Rookie Manga Award. Umezawa currently lives in a one-room apartment and has grown his hair out longer and has a small mustache. However, he still cheers on Ippo and attended Itagaki's Rookie King match.

Since then, Umezawa has cleaned up his appearance, retaining a minor goatee and trimming his hair. He's been working as an assistant to the artist who does the weekly comic "The Town You're In," a Slice of Life romantic comedy made for kids, spin-off of "A Town Where You Live". Umezawa still keeps up with Boxing Fan and was upset about Ippo being mocked by Kojima Hisato.
