The Ramparts of Ice Season 2 English Dub Streams Trailer

The Ramparts of Ice (Koori no Jyōheki) kicked off its second season on Thursday, and on the same day, Netflix released the English dubbed trailer. The preview is the English version of the second promotional video and features Escort, the opening theme performed by four-member band THE BEAT GARDEN. Superfly, for their part, handles the ending theme with Hanakage.

The series follows Koyuki Hikawa, a distant high school student who puts up a wall between herself and others. She spends her time alone at school, but Minato Amemiya keeps trying to get close to her. The coming-of-age story is rounded out by Miki, the popular girl, and Yōta, an easygoing guy. Four characters, each with their own complications.

It's not a premise that reinvents the wheel, but the manga found its footing. Kōcha Agasawa serialized it as a webtoon on the LINE Manga app between January 2020 and April 2022, and Shueisha published the 14th and final compiled volume in February 2025. Before that, the title had already made waves in rankings and awards: 15th place for male readers in Kono Manga ga Sugoi! 2024, a nomination at the 69th Shogakukan Manga Awards in 2023, and second place in the vertical scroll comic category at the Rakuten Kobo E-book Awards in May 2024. At AnimeJapan 2023, it placed second in the "most wanted anime adaptation" poll.

Release and platforms

The second season airs in Japan on Thursdays at 11:56 p.m. on TBS and 27 affiliated channels. Netflix streams it globally, along with other Japanese platforms. The first season premiered on April 2 and also hit Netflix the same day. There's no gap between the Japanese broadcast and the international release here; it's one of those cases where the platform moves fast with the dub.

The dubbed trailer dropping on the same day as the premiere says a lot about the priority Netflix is giving this title. That's not the norm: many series wait weeks or months for an English version. Here, the material was ready from the start. The strategy makes sense considering the series arrived with a fan base built from the webtoon and with recognition at major awards.

Agasawa had already shown he knows how to work in this space with You and I Are Polar Opposites, another of his works. His style of characters who can't quite communicate and relationships that move forward in fits and starts carries over to The Ramparts of Ice. The anime adaptation doesn't have a major studio behind it or a staff that generates headlines on its own, but the source material is solid.

What's left to see

The dubbed trailer confirms the opening and ending themes are already set, and that the international promotional machine is up and running. What's still unclear is how many episodes this second season will have and whether it will adapt all the way to the end of the manga, which is already complete in 14 volumes. With the first season as a reference, the most likely scenario is that the series moves into the second half of the story.

The second season of The Ramparts of Ice is now airing. The question, as always with these stories about closed-off characters who gradually open up, is whether the adaptation will manage to keep pace with the source material or settle for skimming the surface of the youth drama.
