Key begins to fixate upon the idea of becoming a pop idol herself as the surest way to making 30,000 friends. In the meantime, Ajo's team are trying to determine whether she might be where Dr. Mima cached his last technological secrets before dying. When Key's presence (care of Shuichi) disrupts Miho Utsuse's latest concert, the company sends out two PPORs to hunt Key down, remotely controlled by a dangerous operative known only as 'D'.

As if to confirm earlier hints that Key possesses a phenomenal power whose exact nature is hidden even from herself, this episode sees her disabling both PPORs and rescuing their secondary target from certain death. However, this display is witnessed by hundreds of passers-by... including Prince Snake-Eye, a spiritual leader who sees in Key a way to revitalise the faith of his cult followers.

Prince Snake-Eye convinces Key to come to his temple. The child of two of his followers is deathly ill, but their faith precludes medical intervention... so he hopes that Key can cure the boy with her 'supernatural' powers. However, Ajo's lead soldier 'D' has finally tracked Key down, and a confrontation between him, Tomoyo, and Prince Snake-Eye ensues.

Sakura, apparently content to put her own dreams on the back burner for a while, creates 'Production Key'... an agency devoted solely to helping Key reach pop idol status. She tries pumping Shuichi for his connections in the music business, but he seems overly preoccupied with the connection between Ajo and Miho Utsuse. (Not that Ajo isn't already lining up a replacement for the day when Miho can no longer perform.) A bored Tsurugi notices Key at an open audition and his interest is piqued by her utter lack of emotion.

Ah, this is a really satisfying episode... so much so that you end up wishing the whole series ran at this pace. First, you've got Tsurugi being Tsurugi. Then there's Ajo trying to milk every drop he can out of Miho. (Recording singles in the ICU, anyone?) Prince Snake-Eye is doing his level best to put the fear of god into anyone who's even thinking about giving Key a try-out. And Shuichi decides now's a good time to go play private investigator in Mamio Valley (where Key and Sakura grew up). Amazingly, he actually manages to turn up a few clues about the life and death of Key's 'grandfather', Doctor Mima. And if that isn't enough action for you, Ajo craves screen time and keeps cropping up, first selecting new girl Beniko as Miho's soon-to-be replacement... and then crossing paths with Shuichi in Key's old village!

Much like the first in this set, everything is geared to reach a climax of sorts in this last episode of the disc. Again, it would be rubbish of me to ruin all the fun for you. Let's just say that everyone who's anyone makes it to Miho's concert. And yes, mayhem obligingly ensues. Oh, and you finally get to properly hear the 'lullaby' song that Key's author has been teasing the audience with for a while now.
