Where Does Justice Lie? Yumika tells Ittoki about the existence of Iga's secret Ninja Core, and informs him that he will only be told its location if he becomes a register ninja of the Iga Clan. The NSC covertly sends word to the 13 major Ninja clans to convene for the Grand Ninja Council, the first one in over 70 years. Ittoki stays behind in the village while Yumika goes to attend the meeting. Goshogawara levels his accusations against the Koga that they have been violating the Ninja Ordinances by unlawfully suppressing or absorbing smaller ninja clans, citing the mysterious disappearance of the Saiga and many other clans. He then calls for the other ninja heads to testify against the Koga, but none stand up except for Yumika, who admits the existence of Iga's secret Ninja Core and points out Koga is looking for a pretext to steal it. She declares that she is willing to destroy the core to keep it out of the wrong hands, and reminds the other clans that their purpose is to uphold Japan's peace, not fight each other. This inspires the other clans to admit that the Koga have been slowly encroaching on them as well. Kidou is arrested, but Captain Karajishi uncovers newly discovered evidence implicating the Iga in Kishinmaru's death, resulting in Yumika's arrest as well. Suspicious, Goshogawara performs his own investigation and discovers something wrong with the evidence, but he is murdered by Karajishi, who reveals himself to be working for Koga. At the Iga village, Ittoki decides to assume the role as the clan's acting chief. Meanwhile, blaming Iga for Kidou's arrest, the Koga declare war and prepare to attack the Iga. At the NSC headquarters, Karajishi sentences Yumika to death.
