This work was produced as the ninth special animated piece for the 24-hour television program by Tezuka Production, which took full charge of the original story, screenplay and director. Tezuka Osamu crafts a love story in the time when humans are expanding into space at the end of the 21st century, employing an omnibus form similar to Bradbury's "Martian Chronicle." The story line is similar to "Phoenix: Nostalgia." Leaving the earth after marriage, a woman is left behind in space when her husband suddenly dies of a cosmic disease. These background details were used in "The Phoenix" as well. This time, her friends on the Earth head for space to save the woman who was once everyone's ideal lady. In this special animated piece, Tezuka Osamu emphasizes his basic concepts that "love can save the earth" and "only love can save humans."

Ryofu Housen (Lu Bu) is a powerful general from the Three Kingdoms; alongside Chinkyuu (Chen Gong), Ryofu suddenly finds himself falling to Earth, and landing... in the body of an elementary school student?! With their new lives as flat-chested, women-loving children, Ryofu and Chinkyuu follow their hunger and their desire to get back to their old lives somehow; but it will be difficult, given the variety of obstacles in their way including old enemies, epic monster battles and the most important thing of all, trying to get their hands on Eri-sensei's mammoth F-cup breasts!

A trip to the beach turns out to be more than expected for two people who are mourning the losses of their beloved. Perhaps a mysterious girl known as the "Umi Warabe" can help them to heal their wounds and move on with their lives. Matsunaga Yoshihiro is the chaperone for a group of high-school students on a summer trip to the beach. One night he saves one of the students, Morisawa Nao, as she attempts to drown herself. She had been on this same trip a year ago, with her fiancee, who was later killed in a plane crash. As these two get to know each other, we find that Yoshihiro also has a painful secret from his past. Watching over everything is a mysterious young girl who somehow is always there at decisive moments.

In deep space, four astronauts discover that their colleague Makimura has mysteriously died shortly following a cryptic note about his imminent murder. Though horrified by the news, the inoperable state of their spaceship leaves the crew no time to grieve, and they evacuate via escape pods. Determined to identify the culprit, the survivors begin to suspect fellow crewmate Kizaki, on account of a rivalry between himself and Makimura regarding the only female team member, Nana Ichinomiya. However, to their bewilderment, they notice Makimura's pod following them, yet failing to respond to attempts at contact. As the astronauts try to interpret their perplexing circumstances, they learn there are more inconceivable stories about their lost teammate, one involving the Phoenix, a mysterious bird said to have the ability to grant immortality. It is not until they crash into a seemingly deserted planet that the crew will finally uncover the sinister truth behind Makimura and his suspicious pod. Set in a distant future, Hi no Tori: Uchuu-hen illustrates the cruelty of human beings passionately in pursuit of their own desires without any regard to the consequences.
