Reito I think is someone who has a lot of spite and anger towards humanity, as he was cursed to death by someone but the fact that he believes that death's jib is not to simply extinquish life makes me believe he is someone thwt - deapite his jaded view point does not think that people are incapable of change . Though he was originally on board with Sunao's death , its hard to say if he really was or if he was trying to teach Sunao something. I think hes a really interesting character, and I wish i could see the stage show to learn more!
