Animation : LAST adult animated series concept and story. by Alex Olguin

Some time ago, I came across a discussion here about adult animated series that don’t rely on cheap shock or explicit content to feel mature.

That idea stayed with me.

So I thought… challenge accepted.

At some point, I also found myself thinking about a recurring idea: the notion that a world without men could be more stable, or even better.

Instead of treating that as a utopia, I wanted to explore what would happen if you actually pushed that premise to its limits.

That eventually became a project I’ve been developing called LAST, a dialogue-light animated mini-series (8–10 episodes) driven by visual storytelling, atmosphere, and rhythm, supported by an aggressive synthwave tone (something along the lines of Carpenter Brut).

The story takes place in a world that isn’t just post-apocalyptic, but actively transforming into something else — where humanity is no longer at the center.

At its core, the series explores what happens when humanity tries to rebuild itself after removing one half of its own system — and the long-term consequences of trying to compensate for that absence through technology, control, and adaptation.

What begins as a controlled transition slowly turns into something unstable, fractured, and increasingly surreal.

As fragmented societies struggle to survive and new forms of life begin to emerge, something else lingers beneath the surface: a system trying to rebuild what it believes to be “perfection.”

The series explores ideas around perfection, divinity, and what it means to reconstruct humanity from its remains — loosely inspired by concepts like kalos kagathos, and how our perception of the “ideal human” is often shaped by incomplete or subjective views of the other.

In that sense, LAST is less about conflict, and more about absence — and what happens when something essential is reduced to an idea rather than a living presence.

At the center of it all, there’s a single anomaly: a man in a world where men are not supposed to exist anymore.

The tone is brutal, but not for spectacle — violence exists in the world, but it’s never the message. The narrative leans into silence, tension, and visual progression rather than exposition.

The first chapter follows a mysterious man, whose name remains unknown, carrying a katana that once belonged to his mother, as he crosses paths with a newly conscious tribe of monkeys threatened by machines designed to erase his kind.

This encounter marks the beginning of a larger journey through a world that will put to the test this man’s will to survive — and his place in a system that was never meant to include him.

Think Samurai Jack / Primal in terms of visual storytelling, but driven by a more conceptual and philosophical core, closer in spirit to something like The Last of Us, while keeping dialogue to a minimum.

Here are a couple of early visual pieces: the main poster and Chapter 1 poster.
