In crafting the main title sequence, we focused on themes that shaped every vignette. At the core was espionage — capturing the tension, secrecy, and intrigue driving the narrative. Equally important was the cultural and emotional bridge between Korea and America, showing how these two worlds intersect and collide within the story.

We also built in high-energy action, paired with intimate character moments that reveal connections, conflicts, and growth, adding both intensity and emotional depth.

Our characters were placed front and center, portrayed in ways true to their personalities and roles. Beyond authenticity, we emphasized visual composition — designing scenes that are as dynamic and compelling as they are meaningful.

Animation was treated as more than a style choice: it was key to the storytelling. We wanted unexpected movement and bold transitions that surprised viewers, sustained their curiosity, and made the sequence feel alive. The goal was to create not just an introduction, but an immersive experience. Our goal was set the tone, build intrigue, and pull audiences into the world of Butterfly from the very first frame.

The team first explored black-and-white styleframes but ultimately chose color for the sequence. From there, we looked to the colors of Korea — testing palettes that ranged from bold and vibrant to more muted, desaturated tones.

The latter won out, echoing the sun-faded, timeworn hues of the show’s real-world locations.

To introduce our hero, David, in episode one, we open with something intimate: a voicemail he leaves for his daughter. This small gesture sets the emotional tone, grounding the audience in David’s humanity from the start. The challenge was to represent that voicemail visually in a way that felt both meaningful and woven into the world of the show.

Our solution was a custom soundwave visualization of David’s voice. Built with layered depth and texture, it feels dimensional and alive, rather than a flat graphic. As the sequence unfolds, the soundwave morphs into the sprawling cityscape

of Seoul, symbolizing the bridge between David’s personal world and the vast, complex environment around him.

This soundwave design does more than open the story. Its style, palette, and layered composition became foundational to the series’ visual language, influencing graphic elements throughout.

The result is a cohesive aesthetic that binds together emotion, place, and character — drawing viewers deeper into Butterfly’s world.

Typographically, we aimed for a style that balanced action and technology, capturing the pulse of espionage that runs through the series.

For the Butterfly logo, we chose Stratum, a versatile geometric sans serif that delivered the precision and strength we needed. The logotype sits against a butterfly silhouette built from dozens of firearms, a striking nod to the original

graphic novel cover. This distinctive mark carries across marketing materials and the new graphic novel editions.

For credits, locators, and other text, we turned to Aglet Mono. By pairing semibold and light weights, we created a clear hierarchy between primary and secondary information while keeping the typography cohesive and functional.
