Ryuji is essentially the opposite of Ren's character. He is loud, abrasive, vulgar and at times obnoxious or completely oblivious. However, he's the most loyal and easygoing of the main cast and is Ren's best friend throughout.

His voice should be brash and quite loud. Following a mostly Mid-High pitch. Keep in mind that he is an incredibly loud-mouthed character, much to the annoyance of the rest of the main cast.

You can look at the game's dub (Acted by Max Mittelman) for reference.
