Akio  is a very popular Fashion Designer from the country of Italy, where all fashion comes from. He was born in a very poor family and had to slowly make his way up, stories say that when he was little he was just fascinated by the clothing worn by the people who participated in steet parades, he used to draw the designs in the only book he had, and then he started making his own.

He tends to stick around people with class and those who wear fashionable clothing, he has a passion for colors and symetry, staying away from those who make an improper use of these...

Though he is Italian, I would try to make two variations of your audition if you are going for this type of accent, keep in mind that he tends to speak in a "Classy" manner.

An example of his voice would be [Yusuke Kitawaga from P5] with a more mid pitched voice.

Here is a reference picture of Akio's design:
