Kagerou

Princess

Kagerou was sold to the brothel by his grandmother shortly after his father's bussiness failed. He resembles his run-away mother which caused his grandmother to dislike him. Kagerou is considered very proud and was even given the nickname 'princess' by Kichou. He has feelings for Kichou but seems to be in denial about them. He and Kichou are fighting for the title of best selling courtesan. (source: evilempire.com, baka-updates, me de shireru yoru no junjou manga)
