He serves as a red herring for most of the game. He wears sunglasses through his appearances, hinting at his being a suspect.

Most of the time, Danno is cool and collected, not socializing very much and appearing quite a bit like Akiyama Shinichi in his decisions. He is calm under intense situations, and likes to observe the action rather than take part in it. While not to the same levels as Akiyama, he is quite manipulative and a smooth talker.
