It was announced during a panel at Anime Expo Lite that Sentai Filmworks has acquired the license for the Shikizakura anime, and that HIDIVE will simulcast the series as it airs.
The story of the series is described as:
In the place of Shikizakura (cherry trees), where autumn leaves and cherry blossoms are flourishing and where the human world intersects with the demon world, a ritual to save the human world is about to begin…
Kakeru Miwa, a high school student, gets involved in a battle between powered suits and oni that emerge from the demon world to prey on Onis manifest themselves in this world by possessing humans. Only “Yoroi,” powered suit that is a fusion of ancient secrets and cutting-edge technology, can protect people from onis. Kakeru puts on a Yoroi by chance and becomes a semi-official member of a team that fights against onis.
Determined to become a hero, Kakeru battles Onis to protect Ouka Myojin, the shrine maiden destined to save the world. In the season of Shikizakura, in midst of autumn leaves and a flurry of cherry petals, Ouka performs a dance as a shrine maiden. At the place where the past and the future, this world and the alien world, people’s thoughts and hopes all meet, a tale of heroic action-adventure begins.
Shikizakura is scheduled to premiere in Japan in October 2021.
