Mimiko is an orphan who was raised by The Company, of which she now works for as a Compromiser. Her first impression of Jirou is not good.

Mimiko's boss calls her very early in the morning and tells her to get down the beach area to look out for a pair of Black bloods. She spots Jirou and runs down toward the 'beam'. She quickly makes up a story about it being for a film. She gets Jirou to his feet, while tugging Kotarou under her arm. She gets them inside, and out of the sunlight.

The restaurant is where they have their first fight. ^_^ Jirou comes across like a jerk, and tells her, that her name is strange. Then Kotarou wakes up and Jirou's attitude changes right away. Kotarou also tells her that she has a strange name. She gives Kotarou a rather yummy looking bowl of fruit and ice cream. She then decides to guide them to the Special Zone.

While walking, Jirou is holding an umbrella, and Kotarou doesn't seem affected at all by the sun, so when Kotarou asks her what's wrong, she says she doesn't understand how they could be brothers, they look nothing alike, and Kotarou isn't affected by the sun. Jirou tells her that they are brothers, and that simply Kotarou isn't affected by the sun, or water like he is, and it's better to just leave it at that. So she does so, and soon after they reach a spot overlooking a park, and the Zone is in site. Jirou informs her that there is an invisible barrier around it, which does not allow certain bloodlines to enter. He then annouces this is where they part ways, but Mimiko doesn't want too. Then Tsang and Wong appear, and try to convince Jirou and Kotarou to join up with them, but Mimiko doesn't want them too, but feels like it's not her place to say anything. Then the Suppression Team shows up shooting and hits Wong in the shoulder, as Jirou grabs Mimiko and Kotarou and jumps down into the park. Here Jirou informs her of his plan, and the 3 go separate ways.

Episode 3. Mimiko is running around trying to find Kotarou, and finds him down an alleyway talking to Tsang who is holding up an injured Wong. Tsang gets Mimiko, along with Kotarou to come back to their hideout.

Mimiko folds an origami crane for Chan, who is delighted to receive it. Kotarou folds an airplane and throws it. Chan's face lights up as Wong enters the room with tea, and fully recovered. Her and Mimiko talk, while the kids run off to play.

Mimiko asks Wong if her wound has healed already, and Wongs says: "Yes. I had a fresh drink, after all." She then grins showing her fangs, and Mimiko gulps. Wong then inquires why she didn't give Jirou any blood, and she reacts awkwardly to the suggestion and blushes. Wong informs her that it would be 'immensely pleasurable', better than sex. Mimiko spits out her tea, and enters into embarrassed rant mode: But it will poison her mind! And it's forbidden for Company staff to offer their blood! Mimiko starts to say that Jirou may be a Kowloon, but Wong tells her that isn't so. Wong says she's heard some rumours, that he was a 'consanguineous killer, that he's infamous’ and that if he had sucked her blood, he could have easily broke through that siege.

Mimiko inquires about something Wong said earlier, that if Jirou was a Kowloon Child, that they would still accept him. “Why? You’re aware of their infectiousness, aren’t you?”  That all a Kowloon has to do to control someone is to suck their blood, even black bloods.  That such beings cannot be aloud to exist.  Wong expresses that Kowloon Children have been abandoned just like those in her group.  Mimiko tells her otherwise.  That just one Kowloon Child could control half the world’s population, but that hasn’t happened because after drinking their blood, the victims are killed. 

Mimiko after being asked why she came back to the hideout with them, states she’d new at this and wanted to see it through till the end.  Then she tells Wong that she was an orphan.  Wong starts laughing at her, but then asks her to take care of them. 

Then the Suppression Team arrives.  Mimiko tries to stop them. Wong surrenders, but Badrick commands them to fire, they refuse, so knocks Mimiko to the ground and fires at them.  Wong is saved by the Hind Hand, and Tsang reveals himself as the Kowloon Child, and then reveals his controlled army.  That’s when Mimiko freaks out about where Kotarou is. Tsang after dealing with Badrick, approaches Mimiko, ‘to thank her’ as the Ultraviolet Rays are destroyed, and Jirou arrives.  He asks where his brother is, Tsang reveals him bound and gagged, with Chan guarding him.  When Tsang announces they will be going to a new location, the Zone, and that they’ve already been invited, Mimiko realizes what she’s done.

Episode 4.  Mimiko offers her blood to Jirou, and he accepts, but on the wrist, and not the neck.  He then points out the drool on her face. Embarrassing!  Mimiko takes the bike, with Wong, as Jirou flies over head.  Showdown on the bridge.  Mimiko watches in horror as Wong shots the controlled Chan, and later with sadness as Chan turns to ashes.  u__u    Mimiko points out the reports, and tells everyone they can get away from them in the Zone.  She invites Jirou and Kotarou (remember she already invited Wong), and they proceed towards it.  Wong leaves them as they arrive, to bury Chan’s remains.  Mimiko offers her place to Jirou and Kotarou. And there’s that lovely ‘Hentai! Hentai! Hentai!’ line. XD
