The Ramparts of Ice anime revealed a new trailer ahead of the April 2 premiere date. Netflix will be streaming the anime. The new trailer shows off the opening theme song by Novelbright, titled "Toumei":

Studio KAI is animating the series with Mankyuu as the director and Teru Ishii as the director. Yasuhiro Nakanishi is doing the series composition, and Miki Ogino is doing the character designs. Kanade Sakuma and Natsumi Tabuchi are composing the music. Poladot Stingray is performing the ending theme song, "Sakasama." The cast includes:

The anime is based on the Koori no Jouheki web manga, written by Koucha Agasawa and serialized from 2020 to 2022 on Line's Line Manga digital platform. Shueisha published the series in print and compiled the chapters into 14 volumes. MangaPlaza licensed the series in English.

Netflix describes the plot of The Ramparts of Ice anime as:
Koyuki Hikawa is a socially withdrawn student who keeps an emotional wall between herself and others. The only person she spends time with is her childhood friend, Miki Azumi. One day, Koyuki's quiet life is disrupted when a boy named Minato Amamiya inexplicably starts trying to break through her barriers.
The aloof Koyuki, the popular Miki, the overly familiar Minato and the laid-back basketball player Yota share an awkward, occasionally frustrating, yet wholesome student life.
An ensemble drama shaped by the crossed paths of youth is about to begin.
