The official website for the anime film series inspired by Japanese stationery company San-X's popular mascot character brand, Sumikko Gurashi , today released a main trailer and visual for the upcoming fourth installment, entitled Eiga Sumikko Gurashi: Sora no Okoku to Futari no Ko ("Sumikko Gurashi The Movie: The Sky Kingdom and Two Children"). The trailer features the film's theme song "Kimi no Kasa" ("Your umbrella") sung by singer Kaela Kimura. Eiga Sumikko Gurashi Sora no Okoku to Futari no Ko Main Trailer The taglines on the main visual read: "if it's the two of us. If we're all together." and "A gentle adventure that will surely become a treasure." Kimura, who wrote the lyrics of the theme song by herself, shared the following comment: Each of the Sumikko Gurashi characters has their own little inferiority complexes and worries, and they may be shy, lack confidence in themselves, or feel down when comparing themselves to others. But, because they have friends by their side who accept them for who they are, they are able to move forward step by step. I put my message "It's okay to have weaknesses and doubts. With your friends together, you can overcome any feeling." into this theme song, "Kimi no Kasa,. I hope that this song inspires listeners to cherish "themselves just as they are," just like Sumikko, and gives them a little courage.
