In Episode 43 of Cardcaptor Sakura , a random woman hums the second season opening as she walks to a mailbox. Dororo may ultimately be a somewhat depressing anime, but its opening is anything but. Kirby: Right Back at Ya! Parasimon forces Ruki's memories of her father to the surface, and of a song she used to sing for him—which just so happens to the movie's ending song. This crosses over into Opening Shout-Out territory in the final battle when sequences from both opening credits are used with parts of the second OP playing in the background.
