Stardust Paradise

Once brilliant teenage detective Shinichi Kudo was given a poison that reverted him to a 4-year-old. He's adopted the pseudonym Conan Edogawa so no one (save for an eccentric inventor) will know. Now he's got to solve a series of bombings before his loved ones become victims. Who is this madman and why is he doing this? Only the young genius can save the day but will even he be up to the task?

Agedama is a small boy going to elementary school and having the usual problems for a boy of his age. He is also secretly a superhero-in-training (called "Agedaman"). Along with Wapuro, his floating computer companion, he fights against a criminal organization who can turn humans into monsters of various types.
