As you might imagine, an innocent like Key gets into trouble pretty much the moment she arrives in Tokyo. Aimlessly wandering the streets, she's picked up by a 'photographer' for a 'model agency'... whose main line of business actually seems to be making adult videos. Luckily for her, she's rescued by a chance encounter with a childhood friend of hers, Sakura – who holds down three different part-time jobs but hasn't really decided what she wants to do with her life yet.

As Key settles in as Sakura's temporary houseguest, we get to see a bit more of the other lead characters in action. There's Sakura's friend Shuichi, fan club president for the famous pop idol Miho Utsuse... who herself seems somehow connected to Jinsaku Ajo, the megalomaniac CEO of Ajo Heavy Industries. Also lurking in the background is Tomoyo, Dr. Mima's old lab assistant, who has followed Key to Tokyo in order to keep an eye on her.

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.

After their first big showdown, everyone—good, and bad—are busy regrouping and deciding what their next moves will be. Where does this leave Key? Source: crunchyroll

While `D` recovers from his last battle, Ajo leaves him locked up in  a cell with only a computer terminal ... and a mission. Meanwhile, Sakura and Key are thrilled to learn that Shuichi`s connections are paying off. Source: crunchyroll

The story machinery starts grinding down towards the last of the TV-length Key episodes. Shuichi catches Prince Snake-Eye in the act of sabotaging Key's 'career', but this really isn't nearly as important as what 'D' has managed to do back at the ranch. (No, I'm not going to tell you.) Key – having heard about Miho's concert from Sakura of 'Shuichi only gave me the one ticket and you can't bloody well have it' fame – tries to convince Tsurugi to get her in.

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.

It`s the big reveal, with the meaning of the photograph found in Tomyo village deciphered, Doc`s life story finally told, and Tokiko and Key`s connection ultimately revealed. Source: crunchyroll
