While Mankyu returns as the director, Yasuhiro Nakanishi will once again handle the series scripts. The main cast, including Anna Nagase (Koyuki Hikawa) and Shoya Chiba (Minato Amamiya), will also return to reprise their roles.
The anime The Ramparts of Ice is based on Kōcha Agasawa’s popular webtoon, which was released on the LINE Manga platform in 2020. The story is about Koyuki, a quiet high school girl who struggles to interact with others because she finds it difficult to communicate. Her life changes when she meets the cheerful and outgoing Minato, who helps her come out of her shell. Along with their friends Miki and Yota, the group faces the ups and downs of teenage life while learning to face their insecurities and build meaningful friendships.
