'BLEACH' voice actors Johnny Yong Bosch and Masakazu Morita say a difficult part of voicing Ichigo is expressing the depth behind what isn't written in the dialogue
Bosch said, "It just depends on the level — where does it need to be? Does it need to be subtle? Because sometimes your character will say something but mean something totally different, and you still have to portray whatever the underlying internal dialogue is. ... So at times anything could be challenging that way."
Morita added, "We play the same part, and so I think we really battle with the same kind of intricacies. I have a feeling what you think are the difficult parts are also what I think are. ... I think that the hardest part about Ichigo is trying to express what isn’t being said out loud."
