This is the invaluable Part 1 of Tezuka Osamu's lifework, "The Phoenix," which was never completed.
The setting is the mythical age of Japan in the latter part of the 2nd century. Iza-nagi, who saves the Phoenix's egg from fire started by molten lava, is given lifeblood of the Phoenix as a token of her thanks.
Iza-nagi and his younger sister Iza-nami, who gain 3,000 years of life after taking the blood of the Phoenix, depart for the north in search of a new world with a baby Phoenix, along with the monkey Yota, the rabbit Popo and the tortoise Noro, who protect the child.
Landing on an island, they are given the name "Amaterasu O-mikami" from the residents, and became the living gods of the tribe.
Meanwhile, upon hearing the rumor about the Phoenix, Himiko, the Queen of the neighboring country, Yamatai, orders her follower Sarutahiko to capture it.
The Phoenix (Chapter of Dawn)[Manga Shonen Comic]
July 1954 to May 1955
Appeared serially in "Manga Shonen" (Gakudo Sha)
After the serialization of "Jungle Emperor Leo" in the magazine "Manga Shonen" was completed, the chapter "Dawn" was newly serialized.
However, the serialization had to be discontinued after the eighth issue due to suspension of the magazine publication; thus the work had to be terminated though it was yet incomplete.
Tezuka Osamu later wrote The Phoenix: "Dawn" under a new concept for the magazine "COM." This "Manga Shonen" version, however, emphasizes the fantasy aspect by including such regular characters as a monkey, a rabbit, and a tortoise.
In the "Manga Shonen" version, the mother Phoenix is immortal until her egg is hatched, but she dies of the heat and the flame exuded by the egg at the time of the chick's birth. The setting here differs from those depicted in the subsequent "Phoenix" series chapters.
