A Little Love Letter, a poignant anime by the same studio behind the Helen Keller series, shifts its focus to a Japanese narrative centered around actress Mariko Miyagi and her involvement in the Silk Tree Academy during the 1970s. Through live-action films like The Silk Tree Ballad and Mariko-Mother, she champions the cause of disabled children. This anime delves into the 14-year span of Miyagi's dedication to the academy, exploring her deep connections with the children. Presented in four seasonal segments, the film showcases lifelike character designs inspired by real individuals and boasts storyboarding by the accomplished director Noboru Ishiguro of Star Blazers fame.
