Description
Jun Sekibayashi, originally named Junpei Sekibayashi, is a towering professional wrestler associated with the Super Japan Pro Wrestling organization and a formidable fighter representing Gandai in the Kengan matches. His physical presence is immense, characterized by a dense, heavy-set musculature, broad facial features, cauliflower ears, and a distinctive tattoo around his left eye. While he typically wears his hair in cornrows, he is known to change his hairstyle to provoke his opponents, such as adopting a reversed sumo wrestler's topknot before a match.
Before finding his calling, Sekibayashi was a troubled delinquent who knew no parents, having been raised by his grandmother, and was described as a mad dog with nothing to lose. This all changed at the age of fifteen when he picked a fight with Babadozan Hiroshi, the chairman of Super Japan Pro Wrestling, and was beaten within an inch of his life. Rather than harboring resentment, Babadozan saw promise in the youth's rebellious spirit and recruited him, putting Sekibayashi through a grueling training regimen that saw the vast majority of his peers quit. When Babadozan was fatally stabbed shortly after christening him with his ring name "Hell's Angel," Sekibayashi honored his mentor's dying command to continue training, even on the day of the funeral, and made his professional debut one year later. The lesson that solidified his fighting philosophy came from watching his senior apprentice, Kurachi Karugo, lose a match by refusing to block any attacks. Karugo's explanation that to be a wrestler meant to believe in wrestling left a deep and permanent impression on Sekibayashi.
Sekibayashi is defined by an unwavering and absolute commitment to the principles of professional wrestling. He is a proud wrestler who takes his occupation with the utmost seriousness, adhering to a personal code that forbids him from dodging or blocking any attack. Instead, he believes it is his responsibility as a wrestler to tank all damage head-on, transforming defense into a unique offensive strategy by absorbing and redirecting the force of an opponent's strike back at them. For Sekibayashi, the primary goal of a fight is to entertain the audience, with defeating his opponent coming second. He maintains his in-stage wrestling persona, a concept known as kayfabe, even in the brutal, no-holds-barred context of an underground Kengan match. He has adopted various personas over his career, including the ruthless "Hell's Deva" Marvellous Seki, a character known for extreme deathmatches that brought terror to the SJPW ring for a limited time.
Within the story of the Kengan Annihilation Tournament, Sekibayashi serves as both a major obstacle and a thematic anchor. His first significant role is an exhibition match against the protagonist, Tokita Ohma, where he overwhelms Ohma with his raw power and incredible durability, forcing him to unleash a forbidden technique called the Advance just to keep up. In the tournament's first round, he faces the rogue sumo wrestler Kiozan Takeru. This match becomes a philosophical clash between the worlds of pro wrestling and sumo. Despite Kiozan's immense power, which shatters Sekibayashi's bones and organs, Sekibayashi refuses to fall. He ultimately wins by using Kiozan's own momentum against him, ending the fight with a devastating powerbomb. Severely injured from the bout, he is approached by the young giant Haruo Kono, who asks if he can change his own ways; Sekibayashi grins and agrees to take him on as a student. In the second round, he faces the mercenary Muteba Gizenga. Fighting in his Marvellous Seki persona to demonstrate true pro wrestling to his new disciple, Sekibayashi is eventually felled by a heart jab but rises again, fighting past his limits until Muteba ends the match in a final display of pro wrestling showmanship out of respect. Following the tournament, he officially takes Haruo under his wing, subjecting him to rigorous training to become a professional wrestler.
Sekibayashi's key relationships are built on mentorship and mutual respect. His bond with his late chairman Babadozan Hiroshi and his senior Kurachi Karugo forms the foundation of his life philosophy. His rivalry with Kiozan Takeru is intense, but it stems from his recognition that Kiozan has not yet learned to truly love sumo, driving him to teach his opponent a lesson in the ring. Most importantly, his relationship with Haruo is paternal, as he becomes a patient and demanding teacher who offers the young man a new path and a reason to believe in himself. He also forms a friendly bond with the aspiring fighter Koga Narushima, allowing him to train at the SJPW gym and testing his resolve.
As a fighter, Sekibayashi's abilities revolve around his superhuman durability and a versatile arsenal of wrestling moves. His defensive mastery is unique; he does not defend in the traditional sense but instead uses a technique of "destroying while defending," where he subtly shifts his body to take blows on less vulnerable areas and uses his own resilience to disrupt the opponent's form, turning their power against them. His offensive techniques include powerful slams like the Powerbomb, the German Suplex, and the Argentine Backbreaker, as well as striking moves such as the Arm Whip, a powerful chop that can shatter concrete, and the Backhand Chop aimed at the opponent's chest. He also possesses surprising agility and speed for a man of his size, capable of executing acrobatic dropkicks and surprising skilled fighters with his burst of movement. His incredible stamina allows him to continue fighting and even smiling while enduring catastrophic internal injuries, a testament to his absolute conviction in the power of pro wrestling. Throughout his journey, Sekibayashi demonstrates significant development, moving from a mad dog delinquent to a disciplined performer, and finally to a mentor who seeks to pass on the values that saved his life to a new generation.
