Mondo is a Baritone. We were unable to find a voice for him so no one is singing for him at the moment, meaning the sooner we get a singer for him the better.. The fans have a love-hate relationship with him so he probably will sing a normal amount of times. But maybe more since he's shipped with Ishimaru and Chihiro, two very like and popular ships . He basically sounds like Eminem when singing but his voice is a little more melodious.
