"This is what we call 'Peak Condition'."
— Murobuchi to Yanagi Makoto[2]

Murobuchi Gozo (Japanese: 室淵 剛三 (むろぶち ごうぞう) , Murobuchi Gōzō; "Gozo Murobuchi"), also known as The Immeasurable (Japanese: 測定不能 (そくてい ふのう) , Sokutei Funō), is an affiliated fighter in the Kengan matches and the fighter who represented United Clothing during the Kengan Annihilation Tournament. He was also a legendary decathlete that dominated all areas of track and field.[2]


Murobuchi Gozo is a powerfully athletic man with a strong build, short cropped black hair with a small widow's peak, a long face, with a circle extended goatee beard and confident eyes. He is almost always sporting a confident grin. Murobuchi tends to wear clothes from the United Clothing brand, the company he fights for.


Murobuchi is a confident individual with an indomitable attitude when it comes to overcoming seemingly insurmountable challenges, no doubt due to his background as an unbeatable gold medallist decathlete.


Born to a hammer thrower father and a javelin thrower mother, Murobuchi shocked his family by standing up just 10 days after being born. But it was only in middle school that he became involved in track and field athletics, breaking records in all events. At the age of 16, he represented Japan in the decathlon and for the next 25 years he became dominant in the athletics world, achieving countless victories.[2]

Having become a national hero, his feats surpassing the boundaries of a mere athlete, Murobuchi Gozo suddenly announced his retirement two years ago at the age of 41 and he vanished from the public stage to focus solely on fighting in the Kengan matches.[2] In the Kengan matches, Murobuchi managed to attain nineteen victories with his only loss coming in his eleventh match against Wakatsuki Takeshi.[2]


Kengan Ashura

While sitting on the toilet in the restroom, he noticed Kiozan Takeru annihilating the assassins that had come for his representative position and acknowledged that Kiozan was pretty strong.

When it was his turn to fight, Murobuchi represented United Clothing in the Kengan Annihilation Tournament and fought Wakatsuki Takeshi. Despite putting up a better fight this time around, he still ended up losing to his rival.

Hospitalised, Murobuchi was given new teeth and was soon back on his feet. During Hayami's attempted coup, Murobuchi helped defend the medical area alongside Hanafusa Hajime, Sekibayashi Jun, Inaba Ryo and Kono Haruo. While fighting, they were soon aided by Muteba Gizenga.

The next day, Murobuchi and most of the knocked out fighters from the previous rounds watched the final day of the tournament unfold.

After the Kengan Annihilation Tournament, Murobuchi began doing "top-secret" training in order to take down Wakatsuki.

Kengan Omega

At least a year after the momentous Kengan Annihilation Tournament, Murobuchi was defeated by the Kengan match newcomer Utsubuki Kokuro, though the latter noted that Murobuchi was not in peak condition.[5]

At some point, Murobuchi was brutally beaten up by Akoya Seishu[6], which ended up with the latter being suspended and the former being forced to take an extended leave from Kengan matches due to complications with his injuries.[7]

Power & Abilities

A former decathlete, Murobuchi Gozo has highly developed physical strength, speed and technique. Without any true martial arts experience, he is still a powerful fighter who relies purely on his athletic ability. As a demonstration of his condition for his boss, he demolished a trailer with his bare hands; after this feat he claimed he was at "peak" condition.[2] Despite having no formal martial arts training, he was able to perform a cross arm lock on Wakatsuki Takeshi.[8] However, his greatest asset is his physical speed, being considered the fastest man on earth; using this speed, he was able to perform the "world's fastest flying knee kick" on Wakatsuki.[8]
