Mr. Cartelet is a tall and handsome man with sandy-blonde hair that reaches his lower neck and very small brown eyes. He was depicted in casual clothing, like long shirts and pants.
Mr. Cartelet is rather friendly and warm as it is seen in his sweet and loving smile to Shinobu Ōmiya whilst casually leaning on his mini.
His banter is top-notch, because he's British.
