Chika comes to kill Shintarō in revenge for her father but is overpowered by Shintarō with Shūsaku's help. He persuades her to give up being a ninja and live a normal life tending her father's grave. However, Chidori comes to her and praises her for getting close to Shintarō and says Kongō is pleased with her and wants to give her her father's crest. She goes with her to what she believes is the location of the new Phantom hideout. This is a trap as it is not the real location as Densai tells her before punishing her as a traitor. They fight and she is badly wounded. Shintarō and Tonbei go to the house and are attacked by Densai, Chidori and the other ninja. Chidori uses the blinding snow trick on Shintarō in the house but Chika throws her web on her, allowing her to be captured. She then dies and is buried next to her father.
