Nino is a supporting character in the show and often as supporting character in comics. I do not care if you wish to keep his accent or not, so feel free to do what you want with that. He is often seen in comics, but he does not have too many lines.

Nino is the best friend of Adrien as well as the boyfriend of Marinette's best friend Alya. He is sometimes known as Carapace (the turtle miraculous) in the comics, but that is not done most of the time. Nino is carefree and a loving boyfriend to Alya. He is often seeing supporting Adrien and only wishes that Adrien can hang out more. He has a love of music and wants to be a DJ one day. In comics, he is usually seen as a helper to Alya's plans or support of Adrien.
