Dragon Ball: Sleeping Princess in Devil’s Castle

Released in 1987 as the second animated Dragon Ball feature, this short film captures the series at a moment when its hero was still a boy training under Kame-Sen'nin rather than trading blows with cosmic opponents. It matters chiefly as a time capsule: a theatrical side story produced while Akira Toriyama's manga was still in its early, gag-driven adventure phase, and a clear example of how the property was packaged for cinemas, here as one part of a summer festival bill alongside other Toei shorts. For readers tracing the animation's history, it marks a distinctive era of tone and scale that later entries moved away from.

The experience it offers is brisk and self-contained. In roughly forty-five minutes, Goku and Kuririn accept a test from their would-be master, a mission to recover a fabled sleeping princess from a demon's castle, and the result plays as a compact dungeon-style romp. Slapstick comedy sits beside martial arts exchanges, eerie castle corridors, and mild monster-and-demon menace, so the mood stays playful rather than frightening. Because the story stands apart from the main continuity, nothing here is required homework, which makes it easy to drop into and easy to finish in a single sitting.

Its brevity, gentle content level, and straightforward premise make it approachable for newcomers curious about early Dragon Ball, for younger viewers ready for light supernatural action, and for casual fans who want a quick taste of the cast's training-era dynamic. An English dub and streaming availability lower the barrier further. Think of it as a light appetizer rather than a cornerstone: enjoyable for what it is, and most rewarding for viewers already fond of the characters' earliest adventures.

Goku and Kuririn share the same goal: to become students of the Turtle Hermit, Kame-Sen'nin. The master agrees to train them, but only on one condition. They must travel to a distant castle and bring back the legendary Sleeping Princess. Whichever of the two succeeds will earn the right to study under him, turning a simple errand into a contest between rivals.

The journey leads the pair toward a mysterious fortress set among the peaks known as the Devil's Hand, a place wrapped in old stories about a beautiful princess who has slept there for ages. The castle and its surroundings are guarded by monsters, demons, and other strange creatures, and the legend itself is bound up with the sinister figure Lucifer, who holds sway over the stronghold. Reaching the princess means getting past everything that prowls the grounds.

What begins as a race between two hopeful students becomes a struggle to survive the castle's dangers and to understand what is really happening to the Sleeping Princess. Goku's fearless strength and Kuririn's cleverness are tested as they push deeper into enemy territory, and their competition slowly gives way to the teamwork they will need if either of them is to make it out again.

Dragon Ball: Sleeping Princess in Devil's Castle is the second anime feature film drawn from Akira Toriyama's Dragon Ball manga, arriving in 1987 after the earlier Dragon Ball: Curse of the Blood Rubies and ahead of Dragon Ball: Mystical Adventure. Like those companion features, it adapts the manga's world into a self-contained theatrical story rather than continuing the television storyline, running roughly 45 minutes and told in a single installment.

The film opened in Japan on July 18, 1987 as part of the Toei Manga Matsuri festival lineup, where it screened in a quadruple feature alongside the first Saint Seiya film and the film versions of Hikari Sentai Maskman and Choujinki Metalder. That shared billing placed the movie within a seasonal theatrical program of Toei-linked properties rather than a standalone release.

An English dub produced by Funimation followed in 1998, bringing the film to English-speaking audiences years after its Japanese debut. The movie is also available through Bilibili TV, and its source material remains Toriyama's original manga.

Dragon Ball: Sleeping Princess in Devil's Castle is the second anime feature film in the Dragon Ball franchise, arriving after Dragon Ball: Curse of the Blood Rubies and before Dragon Ball: Mystical Adventure. It takes the Dragon Ball manga by Akira Toriyama as its source material but tells an original story rather than adapting a specific arc, which places it as a theatrical side entry instead of a direct continuation of the main narrative.

The movie was released in Japan in 1987, during the era when the Dragon Ball story was still focused on Goku's early training years. It fits into that period as a self-contained adventure that pairs Goku with Kuririn under Kame-Sen'nin's instruction, so it can be enjoyed alongside the early series while remaining independent of the ongoing arcs that the manga and television anime were developing at the time.

Within the broader franchise, this film shares characters, tone, and continuity touchstones with the mainline works but stands alone as a single feature with a runtime of about 45 minutes. Later English-language releases, including the 1998 Funimation dub, introduced it to audiences outside Japan as one of the earlier Dragon Ball theatrical movies, separate from both the television series and the manga chapters that inspired it.
