Sakura relieves her memories of meeting with Inukai and her sister prior to joining TOKKO. After TOKKO's clash against Gaki demons, Ranmaru receives an anoynymous call from a mysterious person who could provide him information as to the true reasons behind the events behind the Machida massacre years ago. During his investigation, he is suddenly attacked by a lone Phantom demon in the nearby park, specifically the 13th Phantom demon. Later on, he is saved by Sakura and her TOKKO comrade, Inukai when the two killed the 13th Phantom. In a conversation between Ranmaru and Sakura, she warns him not to continue getting involved in fighting the demons anymore. Ranmaru is left baffled by her strange warning. Sakura is left to believe, at first, that some people in the Public Security Investigation Agency were responsible for Ranmaru's appearance in the park

TOKKO had decided to move Saya to a safer place, more specially Ryoko's apartment instead of the Shindo's for her own protection. During Ryoko's surprise visit, she managed to obtain information from Muramasa that he was the inside man paid by Taishi to provide police information regarding the case after threatening him with Ryoko's Colt SAA revolver. Later on, Taishi dispatches Gakis to assassinate all active TOKKO members as a means of further slowing down their investigation against him. Surviving the said incident with help from the Araragi siblings, Ryoko obtains an arrest warrant for Taishi. Despite heavy security, the group was able to penetrate deep into Taishi's mansion, but not before he escaped. After the assault, Ranmaru reaches to find Ryoko's apartment, only to realize that it was ransacked, probably stormed by Taishi's henchmen with Saya held as his prisoner. Taishi's associate in the PSIA later moved in against TOKKO by disbanding it and having Ryoko arrested, on false charges of using a fake arrest warrant and supposedly trying to kill Muramasa, who lead the PSIA agents to arrest Ryoko in her office.
