1000-nen Joou: Queen Millennia

In the year 1999, Earth faces an impending crisis as the planet Lar Metal nears its orbit, threatening humanity's existence. Yukino Yayoi, a junior high school teacher with a passion for astronomy, learns of this looming danger from Dr. Amamori at the Tokyo Observatory. Unbeknownst to those around her, Yayoi is actually Queen Millennia, a figure from Lar Metal who has been observing humanity for a millennium.

As meteors begin to rain down, causing widespread panic, one of her students, Hajime, steps forward to assist her. In the midst of the chaos, Yayoi leads Hajime to a hidden cave beneath the surface, where the fate of both Earth and Lar Metal hangs in the balance. As they confront the challenges ahead, their journey intertwines with themes of duty, sacrifice, and the bonds that connect them across time and space.
