Juuou Mujin Dandivine

Twenty years have passed since the combining robot Dandivine defeated the mysterious Aposdoll invaders, long enough for war to become an old story to an entire generation. Peace has been less kind to toy company Casga, whose success was built on Dandivine's fame and has steadily faded as the legendary machine disappeared from public attention.

Company president Genjuro Shijima dreams of Dandivine's return almost regardless of the cost, only for the impossible to happen when the Aposdolls suddenly reappear in Tokyo. Amid the panic, former pilot Yusaku Kuroiwa calls on high school student Gekiha Shijima to inherit the legendary machine. With an enemy absent for two decades now attacking again, the new pilot must discover why they have returned and whether Dandivine can still protect the world.
