Yokohama Disturbance Part IV.Lu Gonghu's attempt to remove Chiaki is thwarted by Watanabe and Naotsugu Chiba. Mr. Zhou visits Chiaki and appears to cast memory alteration magic so that she will forget about his involvement with her. Saegusa, Watanabe, and Tatsuya go to the detention facility and elicit a confession from Sekimoto on his intention (and unsuccessful attempt) to steal the Magic Thesis project data and locate the relic. Lu Gonghu appears again, apparently to silence Sekimoto, but is defeated by the three and taken into custody.
