A Smiling Key Visual, a Trailer About Missed Connections
The new key visual is deceptively cozy. It shows all four leads (Koyuki, Miki, Minato, and Yota) laughing together in a classroom, a much warmer image than the teaser visual from July. The first trailer, revealed August 28 by Japanese entertainment news site eeo, pulls in the opposite direction: it focuses on how the quartet's feelings keep drifting apart even as they grow closer.
The trailer went up on TBS's official anime YouTube channel, and it doubles as a scheduling announcement. Season 2 keeps the late-night Thursday slot, airing at 11:56 p.m. across 28 TBS-network stations nationwide starting October 1, 2026. Netflix then streams each new episode from October 2, a day after broadcast and ahead of every other streaming service, with the rest following on a rolling basis.
Where Season 2 Picks Up
Based on Kōcha Agasawa's complete 14-volume manga from Shueisha, The Ramparts of Ice follows Koyuki Hikawa, a high schooler so bad at dealing with people that she builds a wall between herself and everyone around her. Her only company is childhood friend Miki Azumi, until a boy named Minato Amamiya starts cheerfully bulldozing through her personal space.
By the time Season 2 opens, the comfortable four-person balance is cracking. Koyuki and Minato have grown into something more than friends, and Yota has told Miki about the feelings he'd carried for years. Some of them speak up, some keep everything buried, and every arrow of affection lands somewhere it shouldn't. That mismatch is the entire engine of the show: the aloof Koyuki, former school idol Miki, zero-personal-space Minato, and the gentle basketball-team member Yota.
Anna Nagase stars as Koyuki, with Fūka Izumi as Miki, Shōya Chiba as Minato, and Satoshi Inomata as Yota Hino. The supporting cast includes Akari Kitō (Nezuko Kamado in Demon Slayer) as classmate Momoka Kuriki. Director Mankyū returns at Studio KAI, with Yasuhiro Nakanishi on series composition, character designs by Miki Ogino, and music from Kanade Sakuma and Natsumi Tabuchi.
Looking Ahead
The broadcast premiere is October 1, 2026 in Japan, with Netflix streaming from October 2. Today's announcement covers the Japanese rollout, but the international picture is promising: Netflix already carries all of Season 1 worldwide, English dub included, so a global release for Season 2 appears likely even though it hasn't been spelled out yet. In Japan, Season 1 is also available on Prime Video, Disney+, U-NEXT, and other services.
For readers who want the source material, Agasawa's manga is finished at 14 volumes and is available in English digitally through the MangaPlaza platform. The series started life as a self-published webcomic on LINE Manga before Shueisha's Margaret editorial team came aboard, which explains its unusual path to a Jump Comics release. The new key visual and trailer are both live now, giving fans a month to brace for round two of this slow-burning love square.
