A Glimpse into the Sky Kingdom with “Kimi no Kasa”
The newly unveiled full trailer provides an extended look at the upcoming adventure for the beloved San-X characters. It not only showcases the whimsical “Sky Kingdom” setting and new characters but also features a preview of Kaela Kimura’s theme song. Kimura herself penned the lyrics for “Kimi no Kasa,” with music producer Yoshiyuki Tsutaya handling the composition and arrangement.
Kimura shared her thoughts on the theme song, noting that the Sumikko Gurashi characters, despite their complexes and worries, find strength in their friendships. She expressed that “Kimi no Kasa” carries the message that “It’s okay to have weaknesses and doubts. With your friends together, you can overcome any feeling,” hoping to inspire listeners to cherish themselves.
The Story: An Adventure in the Clouds
The fourth installment of the Sumikko Gurashi film series transports the shy characters to a mystical Sky Kingdom located above the clouds. The plot centers around a prince from this Sky Kingdom who visits the Sumikko Gurashi’s town to address a serious water shortage, initiating a new and heartwarming story. The trailer also teases encounters with “monsters” in the Sky Kingdom and the appearance of a new character, “Ebifriedon,” a playful combination of Tonkatsu and Ebifried’s tail.
