In the dystopian kingdom of Urunaria, the higher you live, the more you're worth.

From the bold mind of Roku Souna - a gripping sci-fi debut where one boy dares to rise against a world built to keep him down.

In the towering kingdom of Urunaria, society is literally built on inequality. The wealthiest reside at the top, while the poor are confined to the dark, crumbling depths below. For Kuro, a young slave raised by his uncle in the lowest levels, life offers no future - only labor, loss, and silence. But when his uncle is executed by the state, Kuro inherits a mysterious device: Gizmo - a pair of mechanical gloves with the power to grip, scale, and defy the very system built to crush him.

Armed with nothing but this outlawed tool and his burning desire for freedom, Kuro begins his ascent, both up the tower and against a society that deems him worthless.

Blending sci-fi action with sharp social commentary, Roko Souna's Gizmo Riser challenges readers to consider the cost of hierarchy and the courage it takes to rise. Perfect for fans of Blame!, Deadman Wonderland, and Made in Abyss, Roku Souna's daring debut delivers explosive worldbuilding, unforgettable visuals, and a hero who refuses to stay in his place.

Frequently asked questions

You’ve asked, we answered.

Visit FAQ Page

Do you offer free shipping?

We offer free shipping on all orders over $75.

As a small, growing shop, we partner with trusted distributors to ship books directly to you. This allows us to offer a much wider selection while we build toward our first physical space.

We also use tiered shipping, which means the more you add to your cart, the lower the shipping cost per book becomes. So that means, even if you’re not quite at $75 yet, it often makes sense to grab one more volume and save overall.

Why shop with you instead of big retailers?

Every order supports a small, Latina-owned manga shop built by real fans who care deeply about the stories, the art, and the culture around it.

We curate with intention, not algorithms, and we’re building something bigger than a storefront: a space for collectors, readers, and fans to connect.

What is your return policy?

Because of how we currently fulfill orders, we’re not able to accept general returns at this time.

The only exception is if your order arrives damaged or incorrect. If you experience either, please reach out to us at casitademanga@gmail.com
and we’ll be more than happy to personally help you with a damage/error return.

Can I cancel or change my order?

We move quickly to get your order on its way.

If you need to make a change, contact us as soon as possible and we’ll do our best to catch it before it ships. Once it’s on the way, we’re unable to modify the order.
