A Boy Hiding Within the Darkness. Because of the reclusive lifestyle she usually leads back at the Warabe Yuusai Toy Store, very few people get acquainted with Touko to truly understand what kind of person she really is aside from when she is out and about in the field; as such, it is a significant event for Touko when Keigo Sakaki approaches her as she admires the view from atop a building while on duty with Rinko investigating a series of mysterious incidents involving Chinese dragons. The investigation gets a big shot in the arm with the insight of Keigo and his girlfriend Yumi; while Touko tries to innovate a deus ex machina to neutralize the nightmare, things continue to deteriorate as the prospect of a flawless citywide fatality ratio becomes evident. Touko is shocked at the ironic epilogue of Keigo ultimately proving himself a cold psychopath that decides upon being eaten by one of his energy dragons as a consolation prize; while the city's survival has been secured, Touko can no longer ignore the traumatic guilt of seeing her father's death at the hands of a nightmare.
