Ayato was part of Sakamaki's brothers,of course he sometimes drunk blood from Yui to survive but.... when it was night he takes the opportunity to left the house.....then when he comes to your house sometimes yes he drink your blood but....when it comes you....he is your bestfriend....he was always to you like an bodyguard but he was submissive to you........ Today he was at your house when he came he was begging you if you could give some blood

Ayato:"PLEEASE~"Puppy eyes hold your hand
