Synopsis

Four colored orbs chase a dark red one through space. After a brutal fight, only the blue orb makes it to Earth, crashing into Michiru's bedroom. The dark red orb lands too, transforming into a boy who starts illegally breeding Mejiro birds. Things escalate when Michiru's at a flea market and suddenly hundreds of Mejiro birds swarm the sky, attacking people. The yellow, silver, and purple orbs show up and nearly manage to calm the birds down, but violence is about to erupt again. That's when Michiru hears a voice in her head—begging her to save the Mejiro.
