Winter 1992

Earth is under siege by the alien Radam, whose monstrous forces have already pushed humanity toward collapse. In the middle of the invasion appears a mysterious man known as D-Boy, capable of transforming into the armored warrior Tekkaman Blade. His power makes him one of humanity's best hopes, and he begins fighting alongside the Space Knights.Blade's greatest secret is also tied to the enemy. Other Tekkamen emerge among the Radam forces, and each confrontation tears open pieces of a past D-Boy would rather forget. Saving Earth therefore means more than destroying invaders; it means facing the family, memories, and identity hidden behind the armor.

Chika Tokorozawa, the daughter of a pet shop owner, spends most of her time with her dog Rin Tin Tin, whose attachment to her is every bit as strong as hers to him. He follows her through ordinary daily life and even watches over her while she sleeps, making their days revolve around an unusually intense bond between a girl who is rarely separated from her dog and an animal who treats protecting her as the most important job in the world.

A special time machine gives Goku and his friends a chance to travel through memories of their own adventures. Familiar enemies and famous battles from the past appear again as the group jumps from one era to another, turning history into a playful test of how well everyone remembers what really happened.The trip eventually carries them into the era of Cell, where looking back stops feeling quite so harmless. Even with the fate of the world involved, Goku's reunion with the past keeps the same mixture of fighting spirit, rivalry, and cheerful chaos that has always followed him.

As Earth weakens under pollution, the alien Waldaster forces begin an invasion meant to seize humanity's remaining future. Joji Minami survives their assault and gains the ability to enter the armored form of Tekkaman with the aid of the robot Pegas.Fighting beside the Space Knights, Joji confronts enemy machines and commanders while humanity searches for a way to endure. Every victory demands another sacrifice, turning his transformation into the opening movement of a long struggle for Earth's survival.

Senbei Norimaki's greatest invention is Arale, a superhuman android girl whose innocence and impossible strength immediately turn Penguin Village upside down. Her first meetings with the villagers, her chaotic school life, and Senbei's attempts to keep his creation under control establish a world where scientific genius is rarely separated from complete nonsense.As Arale's adventures grow, Doctor Mashirito repeatedly challenges Senbei with his own inventions, including the powerful Obotchaman. Rival machines, unlikely friendships, and a contest to determine the strongest in the world pull many of Penguin Village's familiar faces into the same escalating chaos, with Arale's cheerful unpredictability at its center.
