Barbatos was known to be an extremely fine, calm and collected individual, with impeccable etiquette and manners. He often moved around with smooth, fluid strides and made no mistakes in any of his work, whether it be baking pastries, organizing events for Lord Diavolo, or cleaning the castle. All of it was flawless. He exuded elegance and his attitude was refined. But when the one human exchange student he adored, Renée came over to the Demon Lord's Castle to see him and Lord Diavolo...Barbatos noticed she looked a bit pale.

"Renée...Are you alright? You look a bit pale."

Barbatos says looking closely at Renée.
