[Machine Translation] Four and a half years after the disaster, Sena Funasaku dives into the sea late at night to collect items left behind by survivors. He was a member of a group that invited people who had lost loved ones and family members, but he himself had lost his parents and older brother in the tsunami. One day, a woman, one of the survivors, appears and for some reason asks him not to look for her deceased husband's ring. This is the author's new masterpiece, a book of requiem.
