Suezō Hokari, a wealthy figure with a striking appearance, sports a prominent mustache, sculpted facial hair, and a gravity-defying hairstyle that accentuates his partial balding. As the architect of the Bottleman battle system, he holds authority as chairman of the Bottleman Battle Committee (BMBC), directing the governance and standardization of competitions. His eccentricity surfaces through contrasting attire—pink bunny slippers paired with formal wear—underscoring his blend of whimsy and institutional power.

His name originates from Pocari Sweat, a Japanese sports drink, reflecting the series’ beverage-themed nomenclature. Tasked with administrative oversight, he navigates the BMBC hierarchy, collaborating with executives to uphold the battle framework while abstaining from direct combat. The narrative frames him as a steadfast regulator, his role confined to systemic management without elaboration on personal history, motivations, or expanded development in ancillary media. His presence remains tethered to bureaucratic functions, maintaining the structure he designed.
