Notes:

"Araki said that he used male idol groups and Italian fashion as the visual inspirations for this part. He wanted to design the main cast in a "pretty boy image" to deliberately contrast the taller, muscular protagonists from previous arcs. Araki remarked that the gay undertones found within certain scenes were included as a homage to the eroticism generally found within the fashion industry. He didn't think that events or character relationships had any deeper meanings behind them until fans brought it to his attention" – From the Wiki
Yeah, sure thing Araki
