【Lead | AI Overview Summary】
The HGBF 1/144 Sengoku Astray Gundam is a Gundam Build Fighters kit released on November 30, 2013, priced at 1,870 yen (incl. tax). It layers Japanese-style samurai armor over a slim Astray frame and carries twin swords on the back. The build difficulty is moderate (★★☆☆☆) and takes around three hours. The red-and-white contrast is striking even out of the box, but the small helmet and shoulder ornaments hold loosely, and the finely split head and shoulder parts are easy to orient incorrectly. This review digs into the kit’s contents, build experience, and finished look based on hands-on assembly.
1. Introduction ― A Samurai Take on Astray
This time I’m reviewing the HGBF 1/144 Sengoku Astray Gundam. To be honest, I was skeptical at first about how a Japanese-themed Gunpla would turn out. I’d previously built the Astray Red Frame, so I picked this one as a natural follow-up, but my impression changed the moment I opened the box. The helmet, the shoulder armor, and the twin swords mounted on the back were all more detailed than I expected, and I was drawn in before assembly even began.
It’s one of the most distinctive kits in the Build Fighters lineup, and during the build I more than once thought, “They really did all this at this price?” There were highlights and a few genuine sticking points, so I’ll write it up based on actual experience.

3. Box and Kit Contents
Opening the box, the contents are roughly as follows:
- Multiple colored runners (red, white, gray, gold, clear green, and more)
- One polycap runner (for joints and weapon articulation)
- One foil sticker sheet (to supplement the helmet and armor decoration)
- One full-color instruction booklet with character setting notes
Red and white lead the color scheme, with gold, gray, and clear green as accents, so you can picture the finished look just from the runners. The manual includes setting details, which is a nice touch for soaking in the Build Fighters atmosphere while you build.

4. Assembly ― Difficulty ★★☆☆☆ / About 3 Hours
Build difficulty is ★★☆☆☆, with about three hours as a rough guide. Since the core structure is based on the Astray line, there’s little confusion overall, but the samurai armor introduces a few specific snags I noticed while building:
- The head and shoulder armor are finely subdivided, which makes it easy to get part orientation wrong. Checking left/right and front/back against the manual diagrams keeps things on track.
- The helmet and shoulder ornaments hold loosely, so I cleaned up the gates carefully. Removing nub remnants neatly improved how snugly the small parts seated.
- With so many small parts, knowing their position and orientation before cutting them off the runner makes the work smoother.
It isn’t a hard kit, but it’s one that rewards care with small parts.

5. Out-of-Box Review ― Look, Articulation, Color Separation, Gimmicks
The first thing I noticed once it was assembled was that the red-and-white contrast is even sharper than I expected. Lining it up next to the HGBF Build Strike I’d built before, the Sengoku Astray clearly has finer part division and more dimensional armor across the body. The chest and waist armor in particular read as “layered plates” rather than simple covers, and that’s a detail I really like.
- Design and proportions: The samurai-style armor stands out, sitting on the slim Astray frame without throwing off the overall balance.
- Articulation: Shoulders, elbows, waist, and legs all move well, and the twin-sword pose is achievable. That said, the helmet and shoulder armor interfere easily, so big movements need a little manual adjustment.
- Color separation: Red and white lead, with gold, gray, and clear green as accents. It looks cohesive even unpainted, and the clear green eyes have real presence.
- Gimmick: The two swords mount on the back and can be held in a two-blade stance.
When I tried the twin-sword pose, the shoulder armor interfered a bit and the arm was hard to raise, but shifting the parts slightly settled it.

6. Where It Sits in the Lineup ― Compared to Other Kits
HGBF is known for a varied roster reflecting each in-show builder’s personality, and the Sengoku Astray sets itself apart with a clear samurai-armor theme. Compared to the Build Strike mentioned earlier, it has finer armor division and stronger layered dimensionality. Because it’s built on the slim Astray base, it can pile on armor without the silhouette feeling bloated. It offers a flavor distinct from standard Gundam kits and earns its place on the shelf through sheer presence.

7. One-Point Tips for a Clean Finish
Here are some general recommendations for finishing the kit:
- Gate cleanup: With many small parts whose hold depends on fit, clean gates help everything seat more securely.
- Panel lining: There’s plenty of layered armor and molding, so panel lining tightens the edges and brings out the dimensionality.
- Decoration stickers: Some decoration relies on stickers, and misaligned placement affects the result. Place them carefully, or swap to partial painting if you prefer.
- Top coat: The molded colors already look good, so a flat top coat unifies the texture nicely.

8. Before You Buy
- Distribution: General retail release (out since November 2013). It’s been reissued often and is fairly easy to find at electronics stores, online shops, and Gunpla retailers.
- Stock: As a popular kit, it can be out of stock depending on timing.
- Used market: It circulates steadily on Amazon, Rakuten, Suruga-ya, Yahoo Auctions, and Mercari, with sealed copies often around list price.
- Fit for you: If loose small-part retention or sticker finishing bothers you, decide your approach in advance.

9. Good & More
【Good】
- The samurai-based design has a personality no other HG kit has and catches the eye instantly on a shelf.
- The two-handed twin-sword pose comes together easily and looks especially good on an action base.
- The red/white/gold scheme holds together almost entirely from molded color, so parts don’t look cheap unpainted.
- It keeps the Astray frame while building a unique silhouette from the armor.
【More (points to note)】
- The helmet and shoulder ornaments come loose easily and sometimes fell off when changing poses; careful gate cleanup helps somewhat.
- The two back-mounted swords sit at a fairly fixed angle, making it a bit of a chore to set them the way you like.
- Some decoration relies on stickers, and off placement affects the finish.

10. Score
- Overall: ★★★★☆
- In a word: “The samurai personality and the easy twin-sword pose are the draw. With a bit of care for the small parts, it delivers more satisfaction than its price suggests.”

11. Conclusion
That wraps up the HGBF 1/144 Sengoku Astray Gundam review. The moment that stuck with me most was putting a sword in each hand after assembly—I was genuinely surprised that a Gunpla with this atmosphere can be built for 1,870 yen. On the other hand, the helmet popping off and fiddling with sticker placement meant a few fussy moments.
This kit suits Build Fighters fans and anyone after a design that differs from standard Gundam kits. Conversely, if loose part retention or sticker finishing bothers you, it may feel slightly fiddly. If you’re curious about a Japanese-style MS, it’s well worth picking up.
