【Evolution of Generative AI】The Trajectory of Anime Expression Followed by "nijijourney"
In AI image generation, there are two main styles: anime-style and photorealistic. Within the anime-style category, there are specific styles that have established their own areas of expertise.
Specializing in anime and illustration expression, the image generation AI that continues to captivate creators around the world is "nijijourney". Its evolution is also a history of how faithfully and beautifully we can project the "2D worlds" we imagine in our minds onto the screen.
In this article, we will look back at how that style has changed in three steps.
1. The Dawn: The Challenge of Anime Expression
At first, the very act of "making an AI draw in a Japanese anime style" was a major challenge. Back then, it was an era of trial and error to get the lines just right, as limbs would often be out of proportion or a touch of Western-style painting would inadvertently creep in.
2. Achieving Diversity: The Birth of the "Four Styles"
A major turning point was when it became possible to choose your preferred art style. With just a single prompt specification, you could freely summon different worldviews, such as the following:
Default: A high-saturation, classic, and glamorous anime look
Expressive: A mature touch reminiscent of international concept art
Cute: A deformed, adorable style
Scenic: A style that emphasizes the beauty of the background and the atmosphere over the characters
3. The Latest: Infinitely Expanding Expression Drawers
And now, the precision of depiction has improved dramatically. It goes beyond just "beautiful anime art," and now includes features like pencil rough sketches, ink wash paintings, delicate line art that looks like it was drawn with a G-pen, and even the ability to incorporate individual art styles.
Now that AI has evolved from a mere "tool" into a "good partner" that infinitely expands a creator's range of expression, nijijourney has entered a mature stage where it can draw out individual personalities.
In the generative AI Stable Diffusion, there are also many models (checkpoints) that incorporate this style.
Among them, the one I use is the SDVN7-NijiStyleXL model.
When using this model, you must include (niji style) in your prompt to bring out the characteristics of this model.
Below, I will introduce some examples and their prompts.

niji style, best quality, masterpiece, delicate, intricate details, a close-up portrait of a cute young girl sitting in a vast, vibrant wildflower meadow. She is focused intently on weaving a flower crown with her small, gentle hands. Her face is in soft focus, illuminated by warm, golden hour sunlight filtering through her slightly messy, light brown hair (decorated with a few small braided flowers). She has a peaceful, concentrated expression with a small, gentle smile. The foreground is filled with a rich variety of detailed wildflowers (lavender, chamomile, daisies, clover) and greenery, creating a shallow depth of field (bokeh). The flowers are held close to her chest as she weaves. Her clothing is simple, cozy, and natural (e.g., a linen dress in a soft pastel color). The background is a beautiful, completely blurred (strong bokeh) sea of colorful flowers and distant trees under a soft, diffused sky. High-resolution, cinematic lighting, soft color palette, emotional and dreamy atmosphere.
