This coming-of-age battle narrative focuses on the renowned 17th-century Japanese warlord Date Masamune during his youth. The Date clan derived its name from the Date region within the former Mutsu province, an area that now forms part of the modern city of Date. The anime serves as the inaugural project of the city's "Kirari na Wonder Project" (Twinkling Wonder Project), an initiative designed to showcase local tourist attractions and the region's appeal. Gainax's newly established Fukushima studio will produce the anime, with completion scheduled for the end of March. A private screening is planned for April, followed by showings at anime events and online distribution.
