"Kira... I'm actually standing face-to-face with the real Kira!"
Keen is a character featured in Death Note: Our Truths. He is a 23 year old successful businessman, who at the start of the story, is heavily interested in the Kira case. On his own time he has spent countless hours researching and following the mysterious events that surrounded Light Yagami's death. However, he is not friendly to Kira, or Kira's goals.
Keen is a tall, slender Japanese businessman. He is well-kempt and usually wears suits. His hair is black, his eyes are brown, and he has a small black beard on the edge of his chin. While slender, he is also muscular, and in great all around physical shape.
Keen is a successful business man, and therefore very socially aware. His high sophistication is a front, more or less, for his nighttime obsession with tracking the Kira case. Upon the release of the Kira files to the public, many things about the case were revealed to Keen (and many of them he had already assumed). Besides his work with the Kira case, and his day job, Keen does little else besides exercise. He is unmarried, and in his own words considers women, "A pain in the ass". His morality is actually not with Kira, he is loyal only to the law. He finds what Kira did to be despicable and morally insane. However, a bit hypocritical himself, he has gone to great lengths where the law is questionable to gain knowledge about Kira. He seems unconcerned about this.
As mentioned before, Keen spent all of his time, prior to his introduction, pursuing the Kira case. Upon his introduction he is a businessman, working for Hideki Kiryu, Haruki's father. He is brought home one day to be a motivator to Haruki, to join his father's business. However, when Keen and Haruki get to know each other, they realize that they are both fascinated by Kira. Particularily, Keen's impressive knowledge about the history of Kira, and even more importantly, about his killer L.
It is also revealed at the concluding chapter of the Discovery season, that Keen is being haunted by a rogue Shinigami.
- While character basis for Keen has roots in Teru Mikami's design, the two are very dissimilar, when compared in personality and the actions they henceforth take.
- Keen's name is his own design, taken to prevent his real name (Andrew Young) to be written down in the death note. This is similar to characters such as Near, Mello, and L.
