Lost in Starlight and the Seoul It Imagines

A Korean Animation Worth Revisiting Amid the Demon Hunters Hype

The world is buzzing about K-Pop Demon Hunters. Its mix of pop music, action, and fantasy has swept charts and timelines, pulling global audiences into the energy of K-pop and the backdrop of Seoul. For many abroad, it was their first time being captivated by the city’s neon streets, crowded rooftops, and urban pulse on screen.

But three weeks before the Demon Hunters premiere, another Korean animation had already arrived. Lost in Starlight (이 별에 필요한), released in late May, was quickly overshadowed. Which is a shame, because it offers something different yet equally valuable: a vision of Seoul imagined not only as spectacle but also as a setting for reflection.

Both films are driven by imagination, though in different ways. Demon Hunters creates a pop fantasy of idols battling demons in a neon-lit Seoul, channeling the exuberance of K-pop into a story that families and fans alike can enjoy. Lost in Starlight turns toward speculative fiction. As an SF romance, it situates love and loss within a reimagined city, making structures like the elevated walkway of Sewoon Sangga central to its narrative. The result is not immediate spectacle but a slower unfolding of what Seoul might look like in the future and how human connection might endure within it.

On the elevated path of Sewoon Sangga, Seoul becomes both memory and possibility.

Of course, Lost in Starlight faced limits. The choice to cast film actors instead of professional voice actors drew criticism, with some feeling that the emotional line never reached its full potential. And as a retro-futuristic romance, the genre itself was always likely to appeal to a narrower audience than an action-driven K-pop adventure. Still, those shortcomings should not obscure what the film accomplished.

Because in its own way, Lost in Starlight shows how far Korean animation has come. Its world-building, sense of craft, and ambition to portray Seoul not just as backdrop but as a living presence reflect a level of polish that would have been hard to imagine a decade ago.

The Demon Hunters phenomenon is exciting and full of energy. Yet for anyone who watched it and found themselves drawn to the streets and skies of Seoul, Lost in Starlight is worth seeking out. It reveals another layer of the city, another rhythm, and another way Korea is telling its story through animation. If Demon Hunters is the bold exclamation mark of the season, Lost in Starlight is the thoughtful counterpoint that deserves not to be forgotten.
