Michiru Rescue!

Four glowing orbs of different colors fly through space, chasing after a dark red orb. After a fierce battle, only the blue orb falls to earth, landing in the room where Michiru is sleeping. The dark red orb also appears on earth and changes shape into the form of a boy, who starts to illegally raise Mejiro birds.

Later, Michiru is at a flea market in a park when a large flock of Mejiro birds covers the sky and begins attacking people. The yellow, silver, and purple orbs appear and manage to calm the birds, but violence is about to break out again. At that moment, Michiru hears a voice inside her head asking her to save the Mejiro.
