Keen is a human featured in Death Note: Our Truths. While not assuming the role of Kira, he possesses a Death Note, which he uses at serveral points in the story.
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.
