Disco

Disco (ディスコ) is in charge of the Human Auctioning House at Grove 1. He is a brutal person, who abused and kicked Keimi when first brought to him, but before he could do worse he fainted due to Silvers Rayleigh using his Haki.

He was later seen injured (the anime showing it was Shalulia that caused it when Disco was inquiring about payment for Keimi during the chaos), calling the shop's owner, Shichibukai Donquixote Doflamingo for help - but after the latter told him he could have the shop, as he, Doflamingo, wasn't interested in it anymore because the government was calling the Shichibukai to battle against the Whitebeard Pirates.
