Story[]
According to Luna, they were separated when her owner came to Japan for her primary studies. However, Luna's owner would then prepare to go back to her birthplace where she could meet Tera again. Doraemon was touched by her story, and so he decided to present a song to her, reuniting her with Tera through Anywhere Door, and also conveying Doraemon's feelings to her. Tera and Luna spent some time up in the clouds gazing at the moon, and then returned to their homes.
