Nagito initially comes across as friendly and warm; trying to bring the group together and being generally optimistic. But during the First Class Trial, Nagito reveals a much more twisted side to himself. Nagito has a crazed obsession with hope (believing it to be an absolute good) and expresses how he is more than willing to kill or die for the sake of hope. He appears to love and practically worship his Ultimate classmates and he despises himself, believing himself to be worthless and insignificant. During the class trials, he tends to act as both the biggest help and the biggest hindrance. 

His official English voice actor is Bryce Papenbrook.

Nagito's voice should be somewhere around mid-range and sound somewhat raspy. He should sound like someone you would inherently want to trust.
