At the end of the 21st century, due to war pollution and other problems, the earth is no longer suitable for human habitation. For this reason, humans abandoned the earth and began to migrate to other planets. The first one is the planet of the Proxima galaxy - Liberuti, which means freedom in French. After that, humans developed another colony planet - Kuroliai, which means glory in French. With the hard work of people, they finally survived in the harsh natural environment of Kuroliai, and basically achieved self-sufficiency in food and necessary materials. Suddenly one day, a space fleet of aliens who called themselves "Zor" appeared in the sky above Kuroliai. Their request was to hand over the planet. Humans naturally refused this unreasonable request. In desperation, the war broke out. Kuroliai's defense force, the Southern Crusaders, had to face the powerful Zor alone without the support of the neighboring planet Liberuti. In this war, countless young people stepped forward to defend their homeland. Among them is Jeanne Franca, the captain of the mechanized mecha unit with a cheerful personality and super strong action. There is Marie Angel, a royal sister pilot whose driving skills are not inferior to any man. There is also Leila Issawi, an iceberg beauty who is loyal to the mission and discipline. As the battle continues, Jeanne discovers that her long-time enemy, the neutral pilot of the biological man, is actually a brainwashed human, which forces her to examine everything she has done. The appearance of the mysterious young man Zifrey has set off a ripple in Jeanne's heart. During a mission, her subordinate Bowie met the Zor girl Musica, and the two fell deeply in love. In the name of love, these young people tried to find a direction in the fog of war. But as if to mock the efforts of these young people, the war escalated step by step. The Zor people, who found that the neutral people were gradually unable to control them, finally went to the battlefield themselves. All this indicates that the situation is irreversible. Facing an opponent whose technology far surpassed theirs, the Southern Crusaders launched futile attacks again and again. Although they could not defeat the Zor fleet, they exhausted the bioenergy that was vital to them. It turned out that Kuroliai was the homeland of the Zor people. The mysterious flower, the original Zor, which grew on this planet was the only hope for this endangered race. The elders, who could no longer wait, issued an order for a general attack, and countless precious lives disappeared in this tragic war. In the end, the elders finally came to the holy land where the original Zor species grew. Once it bloomed, it would emit a large amount of bioenergy, which meant that all people would be assimilated into Zor people. At the critical moment, Zifree stepped forward and died with the elders to prevent this catastrophe. The holy land was destroyed by the crashed spacecraft, and the original species disappeared into the blue sky, replaced by the beautiful and sad rain of flowers. However, there was still a plant of the original Zor that survived in the ruins. Will this flower of death that will bring chaos and disaster usher in a new round of war? The original plan for 39 episodes of "Chrono Tribe" was hastily concluded, and the remaining stories can only remain in the audience's imagination. However, a classic American animation series was born based on it, which is the famous "ROBOTECH".
