While enjoying the epilogue of a job well done, Naomi delivers a »Keep away from me!!!« psychokinetic shove to Ichirou before flying home completely unaware that her repulsion sets the stage for the Black Phantom vassal Yuri to initiate her mission. Minamoto's computations on the significance of the thistle found with Ichirou give way to being charged a mission. It is no problem for the girls to apprehend the perpetrator esper even as their mammaries breach their uniforms. Upon finding another thistle, Minamoto decides to stay behind to prosecute an investigation along with some computations only to find that Black Phantom's volition is to wield his esper charges as their vassals. Further inflaming matters, Kyousuke has decided to »rehabilitate« Minamoto by wielding Momotarou to effect the mirage of Minamoto as a 12 year old boy before phasing out. Dr, Sakaki's explanation of the cerebral reconfiguration that has been done gives way to Kaoru and her teammates having the time of their lives with their leader in his child state setting aside for the moment the amplified danger of Black Phantom. The scope of Kyousuke's »rehabilitation« is most emphatically demonstrated when P.A.N.D.R.A. occupies the girls' school and configures everybody's computations as if Mio and Kyousuke have always been their classmates while Minamoto expounds upon his prologue. Akira and Hatsune now in estivation and unable to challenge her, Yuri resumes her mission .
