Shinzou Karino

He was a police officer in Japan and was coming back from Guam on the plane trip. He has a son at home and was a part of Miina's Group after the plane crash. Shinzou at first seemed like a kind man who helped both Akira Sengoku and Kanako Oomori willingly, also allowing them to escape. He offered his help to search for Towa and also teased Akira about having a crush on a girl. Though he teased him, he had also stated it was a good thing to have precious people. He also remarked that his own precious thing is his son, showing quite a bit of affection towards his son. Despite this, in the end, it was revealled he was only keeping track of Akira and Kanako in case they found Towa's dead body. He seemed pretty smart during his time as he had looked as if he was the leader of the adults when separated from Miina Isurugi (Fake). He shown his true colours when Akira found Towa's dead body, then trying to kill both Akira and the rest of his group mercilessly.
