A former prince and his retinue take Hifumi to a world powered by imagination.

Shinichi Kudo is a high-school student who, by using observation and deduction, is good at solving mysteries. While investigating one, he is caught by the criminals that he was watching and forced to take an experimental drug. Leaving him for dead, the criminals disappear. Instead of killing him, however, the drug turns Shinichi into a little kid.
To preserve the illusion of his 'disappearance,' Shinichi adopts a new name based on his favorite author (Arthur Conan Doyle) and becomes Conan Edogawa. Ran, his (actually Shinichi's) childhood friend takes this little boy under her wing and brings him to her home.
Conan now lives at a detective agency run by Ran's father, but his mind is as keen as ever and he continues to solve mysteries... always allowing Ran's father to take all the credit.
As far as everyone's concerned, Conan is just a little kid anyway... even to Ran. This is *extremely* frustrating to Conan since nobody will listen to a 'little boy.' Despite this, Conan has a mission... to find the criminals who did this to him and get the antidote to that drug.

From Tokyopop:
In the year 2068, the Brain Computer, created by humans to be the core of a machine-driven Earth, itself creates Leave, an android that far surpasses the abilities of humans. With mankind now an unnecessary aspect of the Earth ecosystem, Leave, along with her 'father' Fenrir (the human scientist who raised her), destroys humanity and in its stead creates the four 'Mothers' who in turn create an android race modeled on Leave known as the Selenoid.
They divide the world into four parts, each ruled by a Mother, and then further sub-divide the android population into hierarchical levels with the strong at the top and the weak at the bottom. A virtually perfect society ...
And it would have remained perfect if some of the surviving humans hadn't formed a revolutionary group together with some of the lower caste Selenoid with the explicit purpose of overthrowing Leave and delivering the Earth back into the hands of the humans.
