The Spring 2026 anime season brought many new shows to viewers’ screens, and The Ramparts of Ice quickly became a quiet favorite. The series, which adapts Kocha Agasawa’s popular manga of the same name, tells the story of a high school girl learning to lower her emotional walls. The show premiered on April 2, 2026, and has been releasing new episodes every Thursday since then.

Studio Kai handles the animation production for this slice-of-life romance series. The show follows Koyuki Hikawa, a student who keeps everyone at a distance, and Minato Amamiya, a boy who slowly tries to break through her defenses. Unlike many over-the-top romance anime, this series takes a grounded approach to its characters and their emotional growth, which helped it build a steady following over the past two months.

Episode 10 Arrives on Netflix This Thursday
The Ramparts of Ice Episode 10 is scheduled for release on Thursday, June 4, 2026. The episode will follow the show’s regular weekly pattern, dropping at the same time as previous episodes. For viewers waiting to see what happens next in Hikawa and Amamiya’s relationship, the wait is almost over.

Total Episode Count and Complete Schedule
The Ramparts of Ice Season 1 will have 12 episodes in total. The show follows a weekly release schedule rather than dropping all episodes at once. This means viewers get one new episode every Thursday until the season finishes in mid-June.
Here is the complete remaining schedule for The Ramparts of Ice:
- Episode 9 โ May 28 (Available Now)
- Episode 10 โ June 4
- Episode 11 โ June 11
- Episode 12 โ June 18
Some sources initially reported an 8-episode season, but multiple release schedules now confirm the full 12-episode run. The confusion likely came from early announcements before the complete season order was finalized.
Each episode runs for approximately 25 minutes. This is standard for most anime series airing in this time slot.

What Makes This Anime Different
The source manga for The Ramparts of Ice has over 14 volumes of material. This means the story has plenty of content beyond what Season 1 covers. The anime adaptation so far has maintained strong animation quality throughout its run, something that fans have pointed out online.
The story focuses on Koyuki Hikawa, a high school student who lives a structured and predictable life to keep herself safe. She keeps distance from her classmates and avoids emotional connections. Then Minato Amamiya enters her life. He is the complete opposite, someone who reaches out to people he feels are neglected. His attempts to get closer to Hikawa slowly make her question her emotional walls.
The series gained attention because it does not rely on exaggerated drama or forced romance. The slow, natural development between the two main characters feels real to many viewers, which explains why the show kept its audience week after week through the Spring 2026 anime season.
