Episode 21 -
Warning: Spoiler!Akari wakes up in the middle of the night to hear the sound of a train, but she shouldn't be able to and wonders if it's the Galaxy Express. All the cats are out again and I think I'm getting another supernatural episode! I love that Alice's kitten has a stuffed President Aria and attacks it the same way as the live one. The next morning, Akari asks Alicia about the train, but she's never heard it and Akari wonders if she's the only one.
At practice, Akari asks Aika and Alice about the train, but they never heard it either. Alice asks about a Manhome book regarding the “Galaxy Express” and Akari says that she has it. Alice says that it's a train that goes to the land of the dead and Aika warns her again to be careful because she always seems to attract strange things. Alice tells her to never to get on the train if she ever sees it, and scares Aika.
Back at Aria Company, Akari reads the Galaxy Express book and thinks maybe she made a mistake. However, that night President Aria wakes her up and gives her an envelope from the Cat Sith that contains a ticket for the Galaxy Express. Later that day at practice, Akari tells Aika and Alice that she isn’t sure what to do. She says that she used to get excited and that her heart would race when they met; she still wants to see him, but doesn't think she should. The girls think she's talking about a guy until she says it's the Cat Sith. They say that they would not want to meet him, but Akari says that – “he always gives me a sparkly, exciting and mysterious experience” and Aika hits her with “no sappy lines allowed!”, before resuming practice.
Akari later visits the spot where the train would stop, but it is just an ordinary street. She thinks of her past encounters with the Cat Sith and tries to decide whether or not she should go. She asks President Aria if they should and it certainly sounds like he says that they should go. At sunset, a worried Alicia looks out of the window to see Akari just drifting in her gondola. She takes her gondola out to join her and gets the story of the ticket. Alicia thinks it wonderful, but Akari thinks she shouldn't go and wonders about all her strange encounters. Alicia likens them to Aqua's ocean and says that since Akari wants to learn about Aqua, well then maybe Aqua wants to learn about Akari as well. Alicia tells her that for whatever reason, she has gotten close to Aqua's heart.
Later that night, Akari has made up her mind to go. She goes back to the spot she visited earlier in the day, but this time there are train tracks, a platform and a crossing light. She can’t believe it's the same street, but then the train comes and stops in front of her. When she looks around, all the cats are there with their tickets and it looks as if the Cat Sith is the train conductor. He stamps the tickets as the cats board the train, but one little kitten doesn't have a ticket and the conductor won’t let it board. Akari steps forward and gives her ticket to the kitten. She guesses the conductor is the Cat Sith and she thanks him for saving her at the graveyard, as well as inviting her to ride the train. He pats her on the head and then takes her face between his paws, as she asks him a series of questions. He doesn't answer her, but instead stamps her forehead and President Aria's forehead as well. Akari thanks him and watches the train depart. The conductor rides at the back of the train and bows to her, removing his hat to reveal himself as the Cat Sith. She nods back as the train launches off the bridge and up to the stars. She believes that it really was the Galaxy Express and promises President Aria that someday they will ride on it too.
Akari wakes the next morning to think that it was all a dream, but then she sees the stamp on President Aria's forehead, and looking at her own stamped forehead in the mirror, she knows that it wasn't a dream after all. She tells Alicia about what happened and Alicia wisely tells her that she wants to learn more, but is afraid to find out, she wants to get closer, but can’t judge the distance, but that they “finally took a step towards each other”. Akari wonders if the Cat Sith could be Aqua's heart after all. She later writes of her experiences to Ai and Ai tells her that she'd like to encounter Aqua's “mysterious wonders” with Akari someday.
