The origins of the great UFO Robot Grendizer come to life in this manga based on the hit Anime Grendizer U.

Fans of mecha anime will love to discover the origins of one of the most heroic characters in the Mazinger series.

When a UFO from the Vega Alliance arrives on Earth, humanity faces its biggest threat in an oncoming Alien invasion. But their hope arrives in another Alien, Duke Fleed, a refugee of the planet Fleed who finds his home in Japan. Duke pilots the mighty Grendizer, a weaponized Mech to fight off the Vega forces. Along with his best friend and partner Koji Kabuto, they fight to free Earth from the terror of the Vega forces.

Written by the legendary Go Nagai and illustrated by 8KEY, Grendizer: U The Inception modernizes the iconic story of the lost prince who shoulders the responsibility to protect his new home from the same Empire that destroyed his last.

Featuring a prequel story by Tatsuto Higuchi not told before, this manga is an adaptation of the anime Grendizer U.

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.
