Creating a high-fidelity cosplay of Justina Gu (known as Yin Ziping in the game) from Naraka: Bladepoint requires a precise fusion of Chinese wuxia aesthetics and translucent ice magical effects, all built from accessible materials like EVA. This guide covers everything from visual deconstruction of the character to technical armor construction, with special focus on structural adaptation, realistic ice effects and painting and finishing techniques that ensure a professional result. If you seek an authentic Naraka Bladepoint cosplay, this is the definitive resource.
Visual deconstruction of the character
Justina Gu, or Yin Ziping, is a medical warrior from Naraka: Bladepoint, whose design combines traditional Chinese attire with powers based on ice energy and healing. Her look is marked by a balance between lightness and structure, where rigid armor elements merge with fluid fabrics and translucent details that evoke ice crystals and vital energy. The silhouette is defined by broad pauldrons with rounded edges, symmetrical chest plates and a structured skirt with overlapping layers, all inspired by wuxia armor — a style mixing Chinese martial fantasy with magical and mobility elements.
The dominant colors are icy white, pale blue and metallic gold, with details in crimson red referencing symbols of Chinese culture, like yin-yang and floral patterns. The use of translucent EVA is essential to replicate cosplay ice effects, especially on pauldrons, arm bracers and chest details. Light passes through these pieces, creating an internal glow that simulates real ice. The armor is not massive, but rather strategic, with plates that seem to float over a fabric or silver mesh base, suggesting lightness and agility.
The main challenge lies in the representation of Chinese patterns in EVA without losing durability. Elements like stylized dragons, clouds and lotus flowers appear in low relief, often with metallic edges. These details are not merely decorative — they are part of the visual language of evolutionary cosplay, where each piece tells a story. When replicating this style, it is crucial to understand that the wuxia armor tutorial is not about faithful copying, but symbolic interpretation. For example, a gold edge does not need to be hand-painted if a spray fool’s gold is applied with a mask.
Anticipating the next question: "How to choose between opaque and translucent EVA?" The answer lies in the function of the piece. Use high-density EVA (5-10mm) for main structures like pauldrons and chest plates, and reserve translucent EVA only for areas that need to transmit light and transparency, like pauldron tips or side skirt details. This reduces cost and weight while maintaining visual impact.
Priority pieces: what to build first
To ensure the Justina Gu cosplay is immediately recognizable, you must prioritize the pieces that contribute most to the silhouette and visual identity. Not everything needs to be done at once — an evolutionary cosplay allows for building in stages. The three priority pieces are:
-
Pauldrons with translucent ice effect
They are the most striking element of the look. They have a shape of overlapping petals, with curved edges and hollowed-out centers displaying inner layers. Use light blue translucent EVA for the core and white or silver EVA for the external structure. The contrast between opaque and translucent is what creates the illusion of ice depth. -
Structured chest piece with raised Chinese patterns
The central chest plate is the heart of the design. It must contain a stylized dragon or lotus flower in high relief, with gold edges. Use 8mm EVA for the base and 3mm EVA for details on top. Symmetry is crucial — any imbalance breaks the harmony of the wuxia look. -
Skirt with overlapping layers and metallic edges
It is not a common skirt, but a set of curved plates that move with the body. Each layer should be slightly larger than the previous one, creating a cascading effect. Use 5mm EVA for rigidity and gold spray paint on edges to simulate aged metal.
Building these pieces first allows you to test the cosplay ice effect in real environments — under natural and artificial light — before moving on to smaller details. Additionally, the chest piece and pauldrons define the vertical axis of the cosplay, making it easier to adapt arm bracers, belts and greaves later.
Other pieces, like arm bracers, belts and greaves, can be made later, but must follow the same palette and technique to maintain cohesion. The ideal is to create paper prototypes first, adjust on the mannequin or body, and only then cut the final EVA. This avoids wasting expensive material.
Common mistakes and practical solutions
Even experienced cosplayers make mistakes when working with Chinese EVA armor and cosplay ice effects. Knowing the most common ones allows you to avoid or correct them quickly.
Mistake 1: Translucent EVA yellows or clouds over time
Translucent EVA exposed to sun or heat can yellow, destroying the ice effect.
Solution: Use resin varnish with UV protection, such as Varathane Clear Finish, or apply a thin layer of epoxy resin with anti-UV additive. Store the cosplay away from direct sunlight. Test on a small piece first: leave under light for 24h and check the coloration.
Mistake 2: Metallic paint peels when bending EVA
Common metallic paints do not flex with the material, cracking at hinges.
Solution: Use paints specific for flexible plastic, like Krylon Fusion for Plastic or Motip Dupli-Color. Apply in thin layers, lightly sanding between them with 600 grit sandpaper. Test flexibility: bend the piece after drying — paint should not crack.
Mistake 3: Translucent pieces don't shine like ice
Many cosplayers paint translucent EVA, but lose transparency.
Solution: Paint only the edges, leaving the center transparent. Use acrylic paint diluted with water (1:3) for translucent layers. For depth, paint inner layers of overlapping pieces with darker blue. The final effect should be of ice with inner layers, not colored plastic.
Mistake 4: Armor is too heavy or doesn't fit the body
Large structures like pauldrons can unbalance the cosplay.
Solution: Use carbon fiber rods or coated wire to support external pieces, connecting them to the base vest with industrial Velcro straps. This distributes weight and allows quick removal. Test-fit before permanent gluing: piece must move with the body without pressing shoulders.
These mistakes are predictable — and avoidable. Always make cardboard prototypes or cheap EVA before using final materials. This saves time, money and frustration.
Safety and handling considerations
The use of materials like EVA, resin varnish and thermal tools requires rigorous precautions to ensure safety during and after construction. Always work in a ventilated environment, especially when sanding, gluing or spraying paints and varnishes. Use an N95 mask or respirator with VOC filter to avoid inhaling particles and toxic vapors.
When heating EVA with a heat gun, keep extinguishers or water nearby — the material is flammable above 140°C. Use silicone thermal gloves for molding, avoiding burns when handling hot pieces.
For LED-lit pieces, completely isolate electrical connections with heat shrink tubing and position the battery in a ventilated compartment. Check heating periodically during prolonged use at events. Never leave lithium batteries charging unattended.
Store the assembled cosplay in a dry, dark and cool place to prevent yellowing of translucent EVA. Cover with TNT or fabric to protect against dust and light impacts.
Practical adaptation of construction
Building a wuxia armor tutorial in EVA requires practical adaptations to make the look viable in the real world. The original game design is stylized but does not consider ergonomics, mobility or weight.
First, simplify complex curves. Instead of cutting each pauldron petal individually, create a circular mold and cut in concentric layers. Use a heat gun heated to 130°C to shape edges upward, simulating the effect of frozen petals. Temperature is critical: below 120°C, EVA does not mold; above 140°C, it burns and shrinks.
Second, create a light structural base. Use a neoprene vest or stretch mesh as support for main plates. Secure pieces with high-strength Velcro or Velcro strips with clips, allowing adjustment and removal. This is essential for conventions, where you will need to sit, walk and take photos in dynamic poses.
Third, integrate cold lights (optional). To intensify the cosplay ice effect, use addressable RGB LED strips (WS2812B) inside translucent pieces. Power with a hidden 3.7V battery in the belt. Configure for light blue glow or soft pulsing. Use Arduino Nano controllers programmed with slow pulse effects. Test heat dissipation: the strip should not heat too much in contact with EVA.
Fourth, simulate fabrics with textured EVA. Parts like sleeves and skirts have a silk appearance. Use 2mm textured EVA with silk pattern (sold as EVA fabric) or create the effect with sponge painting using opaque and semi-opaque silver paint. The contrast in sheen simulates fabric folds.
Materials and execution strategy
The choice of materials defines the success of the Yin Ziping cosplay. Below, the complete list with specific products and their functions.
Mandatory materials
- 8mm EVA (high density) – for main structure (chest plates, pauldrons, skirt). Recommended brand: EVA Branco Nacional (R$12/m²) or Worbla’s EVA Board (premium, R$45/m²).
- Ice blue or crystal translucent EVA – for ice effects. Brand: Foamiran Transparent Blue or EVA Cristal Nacional.
- 40W hot glue gun – for quick gluing. Brand: Tramontina or Mondial.
- Contact glue (optional, premium) – for permanent joints. Brand: Acrilex or Cascorez.
- Metallic spray paints – aged gold, silver and ice blue. Brands: Montana Gold (6000K), Linhafix (Ouro Envelhecido).
- Resin varnish or epoxy resin – ice finish. Products: Varathane Water-Based (safe) or System Three Clear Epoxy (professional).
- Tools: Olfa utility knife, metal ruler, heat gun, sandpapers (180 to 600).
Optional materials
- WS2812B RGB LED strip – for internal lighting.
- Arduino Nano + 3.7V battery – light control.
- Painting mask (N95 respirator) – safety when sanding and spraying.
- Silicone molds (for Chinese patterns) – speeds up detail production.
The execution strategy should follow this order:
- Create all molds in kraft paper based on game references and cosplayer photos (like 米奈minako in the high-engagement video).
- Test on body with masking tape, adjusting symmetry and mobility.
- Cut the final EVA with sharp utility knife, changing the blade every 30 cm of cutting.
- Shape curves with heat gun at 130°C for 5 seconds per area.
- Assemble layers with hot glue, leaving visible joints for correction.
- Paint with spray in thin layers, keeping the nozzle 15cm away.
- Apply resin varnish in a dust-free environment, with 24h cure between layers.
Up to this point, each piece must maintain its shape without collapsing, and the joints must withstand light manual twisting.
Step by step
1. Create paper patterns with dimensional accuracy: use game references and real photos to trace each piece at full scale
Download high-resolution images of Justina Gu from Naraka: Bladepoint and use software such as Photoshop or GIMP to align proportions. Print at 1:1 scale (setting resolution to 300dpi) and cut out each piece. Glue onto kraft paper with double-sided tape. Mark articulation points (shoulders, waist) to ensure fit.
Checkpoint: When placing the pattern on the body with masking tape, symmetry must be perfect and movement must be free. Adjust before cutting EVA.
2. Cut EVA sheets with a sharp craft knife: use a metal ruler and cut in several light passes
Never try to cut 8mm EVA in a single stroke. Make 3-4 passes with increasing pressure, always keeping the blade perpendicular. Use a large cutting mat (A3 or larger). For internal curves, pierce holes with the tip of the craft knife before cutting.
Checkpoint: Edges must be smooth, without jaggedness or misalignment. If there are irregularities, sand with 180-grit sandpaper.
3. Shape pieces with a heat gun: heat EVA to 130°C and form smooth curves with heat-resistant gloves
Hold the nozzle 5cm from the surface and heat for 5-8 seconds until the EVA becomes pliable (not melted). Use silicone gloves to shape the curve with your fingers or with a wooden mold. For petal-shaped shoulder guards, heat each section separately.
Checkpoint: The piece must maintain the shape after cooling. If it returns to flat, heat for another 2 seconds.
4. Assemble layers with hot glue: start from internal structures and work your way to external ones
Use clear glue sticks and apply at strategic points (not in a continuous line). Press for 10 seconds. For translucent pieces, use thin contact adhesive to avoid bubbles. Let dry for 1 hour before handling.
Checkpoint: The structure must be rigid, without creaking or peeling when pressed lightly.
5. Paint with spray in thin layers: wear a mask and work in a ventilated area, applying from 15cm away
Shake the can for 2 minutes. Apply 3 thin layers, with 10-minute intervals. For Chinese patterns on EVA, use paper masks or masking tape for sharp edges. Paint smaller details with a brush and acrylic paint.
Checkpoint: Paint must be even, without runs or dust. When bent slightly, it should not crack.
6. Apply ice finish with resin varnish: brush thin layers and let cure 24h between each one
Use a soft foam brush. Apply in a clean, wind-free environment. For depth effect, add a layer of diluted translucent blue paint before the varnish. Repeat 2-3 times.
Checkpoint: The finish must be smooth and reflective, like wet glass. No brush texture or bubbles should be visible.
7. Mount onto the base vest and perform mobility test: check fit, weight, and security
Connect all pieces to the vest with Velcro. Walk, raise your arms, sit down. Check for pressure on the shoulders or ribs. Adjust straps if necessary.
Checkpoint: The cosplay must move with the body without slipping or causing discomfort. Light-up pieces (if used) must function without overheating.
This complete guide ensures a high-impact Naraka Bladepoint cosplay, faithful to the spirit of Justina Gu and technically sound. With EVA Chinese armor and cosplay ice effect techniques, you create not just a costume, but a moving work of art.
