VRM you can download in mainland China (AplayBox)
Chibi Castorice VRM0_V1.0 (by 0xcchen): A chibi VRM by 0xcchen, hosted on AplayBox and downloadable directly in mainland China without conversion. The rounder head-to-body ratio concentrates detail in the visible area and the model is far lighter than Niko's high-detail version, so it suits modest hardware. Model page terms apply (verified 2026-09-12).Is Castorice a good desktop pet?
Castorice is the performance ceiling of this batch: 52,291 triangles, 516 joints and 36 material slots in 10.7 MB. Every one of those numbers is the highest in the set, and they compound — geometry, skeleton and draw calls all peak on the same model.
The upside is 80 blend shapes, which gives her the widest expression range here. She animates beautifully. The downside is that a mid-range laptop will notice her, and running her alongside other companions is not realistic.
| Spec | Value |
|---|---|
| Triangles | 52,291 |
| Joints | 516 |
| Blend shapes | 80 |
| Materials | 36 |
| Textures | 11 |
| File size | 10.7 MB |
| VRM spec | 0.0 (UniVRM-0.53.0) |
Verdict: the best-looking model here and the most demanding. Treat her as a single companion on a machine you trust.

What it looks like on your desktop
Her white-and-purple palette shines on light and pastel desktops; on dark wallpapers she needs a brighter backdrop or she washes out into a grey silhouette.
Because she is the heaviest model in the batch, the practical advice is to give her the screen to herself. If frames drop, scale her down first — that trades visual size directly for GPU time.
| Setting | Recommendation |
|---|---|
| Wallpaper match | Light and pastel backgrounds; she needs contrast behind her on dark themes |
| Suggested scale | 25-30% of screen height. Triangle count is the constraint, so smaller helps |
| Default placement | Anywhere with a light backdrop; keep her off busy wallpaper patterns |
| Running several at once | Not recommended. At 52,291 triangles she is the heaviest model here by a clear margin |

- Click "Add a companion" and pick the .vrm file you downloaded.
- Adjust size and position, then save.
Extra notes for this character:
- 10.7 MB with 52,291 triangles, 516 joints, 36 material slots and 80 blend shapes — the highest load in this batch on every count.
- VRM 0.0 from UniVRM-0.53.0, so it imports without conversion.
- Modification, redistribution and commercial use are all forbidden. Strictly personal desktop use.
- On a modest GPU, scale her down to 25% rather than removing her — the expression range is worth keeping.

First-wave supply for a new character
Niko shipped a downloadable Castorice shortly after her release, the same fast-response pattern as Varesa. That is good news if you want a new character, and a warning if you expect choice: one version, one author, and no alternative if the terms do not suit you.
She is also the heaviest model in this entire set — 52,291 triangles and 516 joints. New characters often arrive as high-detail conversions first, with lighter fan versions following later.
