Durarara!! Light Novel Volume 06/Epilogue and Next Prologue

The Epilogue and Next Prologue is the ending to the sixth Durarara!! light novel and the Toramaru Arc.

Synopsis
Life returns to normal for Tom Tanaka and Shizuo Heiwajima, who cannot talk about the events of the past few days, and Tom agrees not to ask.

It is discovered by the Awakusu-kai executives that Mikiya Awakusu had hired Slon to kill three spies within the organization. A bystander being framed for the crime would have been ideal for the organization, were it not Shizuo. Unable to handle that particular civilian and with their reputation at stake in the midst of a merge, they have to let Shizuo go. Mikiya instead makes a deal with Drakon to excuse his daughter's actions in exchange for significant discounts on arms and ammunition. The executives Shu Aozaki and Mizuki Akabayashi together corner Vorona and Slon, shooting and capturing Slon and leaving Vorona in the hands of Denis, Simon Brezhnev, and Egor.

Haruya Shiki is suspicious of Izaya Orihara's involvement in -and absence from- recent events. Izaya arrives in a city in the Tohoku region of Japan on the night of his birthday and receives a call from an unknown number. As the man on the other end teases him playfully, he walks by and stabs Izaya in the stomach, introducing himself as Jinnai Yodogiri, the very man Izaya has been searching for, and leaves Izaya bleeding on the sidewalk.

In Ikebukuro, Mikado Ryuugamine has weighed the options Izaya has presented him with, to return to a normal life or dive deeper into the city's underbelly. In his desire to bring back the original Dollars, the Dollars from a year prior who had been excited to belong to something, even if that something wielded no power, he needs help. He meets with Aoba Kuronuma and agrees to fuse the Dollars with the Blue Squares. Catching Aoba off-guard, however, he stabs his junior through the hand with a pen for threatening to bring Anri Sonohara into their conflict. Reverting to his usual self, he quickly apologizes and bandages Aoba's hand, while the gang members around them are left transfixed by his personality change.
