Ryuusei no Rockman

Synopsis

A mysterious melody fills the airwaves of Echo Ridge, causing everyone to fall asleep. Mega Man rushes to the source, an EM Wave Human named Lyra Note. The two battle, and Sonia snaps out of Lyra's control. Later, the two begin to argue, but Lyra agrees to stop controlling Sonia when she sleeps and to stop trying to take over the world. Then, Copper suspects Geo has a connection to Mega Man and follows him throughout the city. Meanwhile, an EM virus unintentionally merges with a disgruntled artist who then goes on a rampage in a museum. Copper locks Geo up in his squad car while he tries to take care of the attack himself.
