The TV anime of Kyouran Reijou Nia Liston — English title Nia Liston: The Merciless Maiden — released its first trailer on July 28, 2026, alongside additional cast and staff and a confirmed October 6, 2026 premiere, per Anime News Network. Here's the setup, who's in it, and where to file it in a crowded fall isekai slate.
Quick answer
Nia Liston: The Merciless Maiden is a fall 2026 isekai adapted by KONAMI animation from Umikaze Minamino's light novels (published by Hobby Japan, 11 volumes as of June 2026). It premieres October 6, 2026 on Tokyo MX, BS NTV, and MBS. Motoki Nakanishi directs, with series scripts by Gigaemon Ichikawa and character designs by Yuki Ito and Kana Tosaoka. The premise: an undefeated warrior-hero dies regretting she never met a true rival, then reincarnates into the frail body of noble girl Nia Liston and sets out to rebuild her strength.

Where it fits this fall
This is a frail-noble-reincarnation power-fantasy — a well-worn corner of isekai, and it'll live or die on execution rather than premise. It's a niche seasonal title rather than a franchise event, so treat it as a wait-and-see. If you want the isekai that already have a track record, our best isekai anime 2026, ranked is the safer starting point, and returning heavyweight Mushoku Tensei Season 3 is the benchmark the genre is measured against. Once Nia Liston airs, it'll pick up a SenpaiRanks score you can weigh against those on the board.
