The Beautiful Girl That Loved Nobita

After seeing a blue bird on his way to school, Nobita gets excited and plans to search for it with his classmates, but they abandon him to go to an idol autograph event instead. Feeling disappointed, Nobita returns home and hears a huge explosion coming from his room, where he finds a mysterious glass case containing a sleeping girl. The girl wakes up and introduces herself as Rurii, a care robot sent from the future, but she was actually deployed by an evil organization led by Walser, who plans to use her to eliminate Nobita. Unaware of the danger, Nobita happily befriends Rurii, while the villains secretly prepare their assassination plot.
