Herurisu / Portrait of a Father.Atsushi and Kyouka are tasked to investigate a mysterious briefcase in one of the yachts at the city's port. Lucy, who has held a grudge against Atsushi for not coming to save her when she let him escape the Moby Dick, deliberately withholds information regarding its location and causes the pair to go on a wild goose chase, with Atsushi almost drowning. Finally with Lucy's cooperation, the three realise the briefcase to contain classified information detailing the deaths of Kyouka's parents, who had been government spies and hence did not have details of their deaths disclosed to the public or Kyouka herself. Her parents were killed in an ambush attack by an ability-user that could control minds. In an attempt to protect their daughter, her mother, who was the wielder of Demon Snow at that time, ordered it to kill herself and passed on the ability to Kyouka. Kyouka reconciles with the ability she once hated, now with the understanding that it is a representation of her parents' love. It is later shown that Koyou was the one who had planted the briefcase as a gift for Kyouka celebrating her formal appointment into the agency.
