Matsumoto, Leiji

In the future, humanity has achieved a vast starfaring civilization, but is slowly and steadily succumbing to ennui or despair, often due to defeat and subjugation by a foreign invader. Rising against the general apathy, Herlock denies defeat and leads an outlaw crew aboard his starship Arcadia to undertake daring raids against Earth's oppressors. Their primary oppressors are the Mazone, a race of organic plant-based alien women who explored Earth in the mythic past and are now back to reclaim it.

Alien In Atami & Other Stories

熱海の宇宙人

Tezuka, Osamu

From time immemorial to the age of space colonization, there is one legend that has stayed unchanged in every history book—the tale of the immortal bird Phoenix. A being whose blood is said to grant eternal life or wisdom, the radiant figure ensures the continuation of sentient life in the universe as it oversees human civilizations and their development.

Yet, mankind remains a slave to its habits; from happiness and sorrow, to wrath and love, a myriad of emotions continue to play an integral part of human life. Simultaneously, time and time again, certain beliefs and agendas persist over the centuries to disturb the fragile equilibrium of the world's preordained nature and principles. It appears that fate, with its dynamic variables, can manifest itself in many ways—and oftentimes exhibits a bizarre sense of humor.

There are  only two rules, Hyun-Bin has to protect Yae-Ha with her life and no one must ever find out that she's a girl. It's a lonely and cold way of life but a fateful encounter with the delinquent Yun-Ha becomes a catalyst of changes to come, where loyalty and a sense of duty clash with feelings of love...

An adaptation of eight Ray Bradbury stories.

1. R is for Rocket
A group of boys dream of one day riding a rocket into space.

2. The Screaming Woman
"When you're living on a street like I'm living on, you just don't think awful things are going to happen. Like shooting, or stabbing, or burying people under the ground, practically in your back yard. And when it does happen, you don't believe it."

3. The Fog Horn
The sea is full of ancient wonders, perhaps even beyond human understanding. And once a year, the sounds of a fog horn reach them...

4. The Lake
Even after years away from the beaches of his childhood, the memories of a young man still remain when he returns.

5. Come Into My Cellar
It seems innocent enough when Mary's brothers receive in the mail their order of mushrooms to grow in the basement, but as the day goes on her suspicions rise.

6. Homecoming
Everyone's coming for All Hallow's Eve, which only serves to remind Timothy how much he feels like the family's black sheep.

7. Jack-in-the-Box
Her house is the world; her deceased father, God. Donna is wildly intrigued by what lies beyond those walls even though her Mother and teacher assure her that there's only death. But... what does "death" mean? 

8. The Rocket Man
Doug's father is a Rocket Man, home at last after a three-month trip. Turns out that working in space isn't as wonderful as it seems, and yet it keeps calling him back.
