"Shiroe/Relationships"@en . . . "Shiroe and Naotsugu have a strong bond and deep and caring respect for one another, having known each other through the Debauchery Tea Party. Because of their four-year bond, Shiroe understands that Naotsugu can defend himself unassisted. Although they are opposites when it comes to personality, with Shiroe being quiet and reserved and Naotsugu being loud and outgoing, the two mesh together well. The first time they met, Naotsugu saw Shiroe drinking tea, and his innocuous remark led Shiroe to go on a lecture about the difference between oolong and black tea, which then led to a discussion about the economics of tea and the condition of the tea market. In volume 9's Debauchery Tea Party relationship chart, it states that Shiroe and Naotsugu are close friends."@en .
