The production team has recently released the synopsis and several cut scenes from the very first episode, titled "Lines and Walls." This premiere episode is scheduled to be broadcast on April 2nd, and the excitement in the anime community is quite high right now.

The story follows a young girl named Koyuki Hikawa, who is a first-year high school student. Because of some deep-seated trauma she faced during her middle school years, she has decided to distance herself from everyone around her. She basically lives her life behind an emotional wall, trying to avoid any kind of social interaction that might hurt her again. Her plan was simply to let the second semester end without any drama or incidents. However, life has other plans for her. One day, she is suddenly approached by Minato Amemiya, a boy from another class whom she doesn't even know. This unexpected encounter is what starts to change her quiet and isolated life bit by bit, making us realize the ramparts of ice surrounding her heart might actually start melting.
Special Pre-Broadcast Program Announced
To celebrate the upcoming release, a special program titled "Special program of Ice Castle Wall right before the TV anime broadcast" will be aired on YouTube. You can catch it on the "TBS Anime" channel starting from 9:00 pm tomorrow, April 1st.
