Adachi, Mitsuru

The story is set in a place very similar in appearance to Earth in the Edo period. However, Adachi (the mangaka) regularly reminds the reader all throughout the series that the setting is another planet in the distant future which just happens to look like Earth.

After the death of his mother, Shichimi sets out to join his step-brothers and -sister who live together in Karakuri Tenement, a place provided by the father they have never met. He finds out that each of them had different mothers (all of whom have died), but were fathered by the same man. Not long after Shichimi's arrival, the siblings decide to journey to visit the graves of each of their mothers. On this journey, they encounter many dangers.

"Alabaster" is a criminal science fiction of suspense depicting the dark side of the human psyche that envies beautiful things.

James Block is a young black man with sinister intentions. When he is in prison, a strange old man tells him about the "F" laser beam that makes humans and any other living things invisible. After he has been released from prison, James receives the F laser beam. But because the beam is imperfect, he becomes semitransparent with an ugly figure. From that time on, he calls himself "Alabaster" and hates anything beautiful.

Using the F laser beam, he begins to eliminate hypocrites and those who boast of their beauty. When living things are exposed to the F laser beam long enough to become transparent, they die. Meanwhile, Dr. F, who told Alabaster the secret of the F laser beam, had previously used his daughter as a guinea pig to investigate its effects. The daughter, who was pregnant at the time, gave birth to a girl. The girl, who was named Ami, is completely invisible. Alabaster approaches Ami and begins to use her for his dark purposes.
