Vodka

ウォッカ
Vodka is mostly seen as the sidekick to Gin, and usually doesn't contribute much to the mission other than being there. Despite his hulking appearance, he is the more easy-going of the two and therefore more suspectible to the traps and diversions which Gin immediately exposes. He calls Gin 'aniki', and he seems like Gin's loyal partner (or subordinate?)
