Kyosuke, Saburo’s grandfather, was killed in New York City, where he was residing, by an unknown assailant.
Saburo decides to travel to New York so that he can go through his grandfather’s belongings and remember the times they spent together.

Soon after, he finds out that his grandfather’s final word was ‘Daedalus.’
