Exploring Character Design
How to use niji・journey smartphone version
niji journey has a discord version and a smartphone app version. You can also use the model by specifying -- niji5 in mid journey This time, we will explain the easiest way to generate on the smartphone app version!
!
Basically, you can create illustrations by entering commands (prompts) here. You can select various styles by pressing the palette icon. This time, we will use it to explore character design, so please choose whatever you like.
!
Niji Journey V5 is convenient for exploring because you can choose various styles!
!
You can change the size on the smartphone version from the ruler mark. In character design, the vertical ratio is the easiest to create, so let's select 2:3 and generate! Since it's about the same ratio as a vertical photo, illustrations are often generated in a bust-up angle if you don't specify anything.
Prompts and generation methods for wall-banging
From here, I will #50DAYS Mom Activity
https://note.com/iamkaho/n/n80f15b4d67dc How to train your character I will introduce to everyone.
What is 50DAYS Mom Activity?
A generation AI project for the streamer puffs. to find herself
An activity to become her own mother in 50 days of continuing to generate one image per day
Discovering her own unique appearance through image generation and image evaluation using niji journey
Announced at Tokyo AI Festival 2024.
- Named after the culture of calling an illustrator Mom in Vtuber culture
Don't forget the settings you prepared in advance, and proceed with generation little by little.
!
The important thing in character design is to think about what changes and how the impression changes. niji Since journey allows you to enter both Japanese and English, let's try generating it first.
!
DAY1 Prompt A red hair Girl at a gaming room
While thinking about which one, Japanese or English, is closer to your ideal, add energy if it's not energetic enough
!
DAY12 Prompt A girl with red bob hair, Vtuber, setting material, street fashion, smile, energy
While trying various methods, leave the elements you want to keep as they are. By repeating this, you can identify the elements necessary for the ideal appearance. Then, compare the finished products side by side.
Compare and evaluate
Evaluate the illustrations created for 50 days in terms of finish and puffs degree (self-likeness).
!
Please also refer to this note if you want to see all the images in detail.
In this project, the finish on the last day was very good, so we decided to adopt it as the main visual!
!
But in fact, the other illustrations that were generated at the same time as this visual were not satisfactory at all.
!
However, the work of refining the prompt is OK after this! Once the direction of the character is decided, the future content development will be stable.
Constructing a character design from the finished illustration
Since this is a project to find your own uniqueness, we will further identify the essential elements as a character design from here. The elements of the illustration with a puffs degree of "★★★" are ・Bob hair with slightly playful hair ends ・Reddish hair and pink eyes (initial setting) ・Street fashion → Including the background, a slightly creative feeling that is naturally in the city
!
In addition to the puffs degree "★★★" Many of the illustrations with a quality of "★★★" also have the same elements It is judged that it is perfect as a basic setting Decided to set it as the base of the character design!
!Images with puffs degree "★★★" quality "★★★"
How to use the completed character design
There are tips for developing content, but first, let's use the completed still images to brand the character. Since puffs. is a streamer, I unified the main images for the profile with the finished key visuals.
!Unified X profile and site icon!
I used the images as they were to create the visuals for the event I actually organized.
How to develop content using niji・journey V6
Once the character design is fixed, you can expect a lot of development by creating other illustrations using the design.
!
You can use illustrations of the same character with different tones to create announcements for distributions. At this time, you can use niji・joureney, which you used to refine the character design, to create it, so I will explain how to do that.
Use the character reference function
The character reference function refers to the image as a character design This is a function that allows you to generate similar images. By making good use of this function, you can use only your smartphone without creating RoLA You can generate character illustrations with consistency.
First, take a look at the image created as a result of working on image generation with the illustration created in [#50DAYS Mom Activity](https://note.com/hashtag/50DAYS Mom Activity) and a small amount of prompts.
!
To use the character reference function on the smartphone version of niji journey, you need to use niji journey v6.
!
Select the palette below the prompt input field
!
When you select Niji Journey V6, you can choose between Default and RAW. The RAW version allows you to set more detailed settings, but since automatic correction is not applied so much, it is better to use the default version unless you are using advanced prompts.
!
Select the image you want to refer to from the character reference. By selecting and inserting the image you created in the previous step, you can generate an illustration of the same character.
*Fujiyoshi's interpretation Image prompt: Refer to the original image Style reference: In a style (drawing style) similar to the original image Character reference: Closer to the character in the original image
Develop character content
Now that you can generate consistent character illustrations, it's finally time to develop character content! Just having an illustration makes it easier to develop goods, so try creating illustrations according to your purpose.
!
Prompt for goods to be sold at club events A red bob hair girl with pink eyes dj at dance club, long shot, low angle, dance club, enjoying smiling, DJ Girl
!Can badges actually sold
Furthermore, create illustrations that match the theme
!
Generate New Year's illustrations using the character reference function. The face has a sharp impression as it is, so I used Photoshop (distortion function) to raise the corners of the mouth and add text.
!
Create LINE stamps with niji・journey
AI generation is not good at unifying the drawing style, but if you create variations in one generation, you can maintain a certain degree of consistency. Taking advantage of this feature, I tried to create LINE stamps.
!
Prompt when I tried to make puffs. stamps with niji journey v5 Emoji, A charming set of red bob hair girl stickers with a white background, line stamps, 9 divisions, red bob hair girl with pink eyes, various poses and expressions, messenger stickers
!
If you know how to generate images using the character reference function, you will no longer be satisfied with this level of character consistency...
I tried doing the same thing with niji・journey V6
!
Certainly, images that could be used for stamps were generated But for some reason, there was only one type or there were small ones around...It felt strange...
Prompt A charming set of red bob hair girl stickers with a white background, line stamps, messenger stickers, 9 divisions, red bob hair girl with pink eyes, various poses and expressions
!
The drawing style was unified, but this will not become a stamp... I will save the images I like for now, so I adjusted the top of the image on the left so that the top of the head is not cut off by using Expand Up. At this time, I used Pan Up.
!!
What a thing. Another illustration came out on top. *Moreover, it's so cute I thought, "If I extend this, I'll get a lot of variations, right?" From here, I extend the images in various directions to create stamps.
!
After generating and finding variations, select the illustrations that can be used as stamps and release them as LINE creator stamps. This time, I used Photoshop to adjust the images, but if you can prepare images with a white or single-color background, you can easily create stamps with the LINE Stamp Maker app.
!
If you use LINE stamps for yourself, you can set it to be free for yourself by not distributing the profits. I'm happy that you can create them for any purpose, such as for pets or family messages.
For details, please check the official guidelines.
These stamps are actually on sale!

Adjust visuals according to purpose
If you use character references, the clothes will also be similar to the reference source... I will tell you how I responded to the theme of "I want to create an illustration for a birthday cafe event!"
Theme: "Since it's a cafe event, I want it to be something that looks like it."
!
First, I tried to find the atmosphere of working at a cafe from the generation other than for cafes so far. However, I felt a little uneasy about whether this was okay for my birthday...Then, I got lost in the idea of "No, it's a maid outfit!"
!
I struggled to create something that looked like a maid outfit, but I forcibly processed the finished images with Photoshop to create a chimera, and then used that chimera as a character reference to solve the problem.
!
I'm very grateful that it makes even terrible crappy collages look like them! I succeeded in generating a maid outfit version with this brute force! If you can draw, you can do it better...
From here, I will proceed with the work of generating a lot and searching for the correct answer. While creating numbers and variations, I will create an event image.
!!
The main visual and sub-visual are complete!
!Main Visual
Main Visual Prompt a red bob hair girl working at a cafe, cafestaff, natural, smiling, cute, a red bob hair girl, pink eyes, with big smile, bright atmosphere, daytime,
!!Sub Visual ①
Sub Visual ① Prompt a red bob hair girl working at a cafe, cafestaff, natural, smiling, cute, a red bob hair girl, pink eyes, with big smile, bright atmosphere, daytime,
!Sub Visual ②
Sub Visual ② Prompt A cheerful birthday party scene in Japanese anime style, featuring a cute girl with red bob hair smiling joyfully. She’s surrounded by colorful balloons, a birthday cake with candles, presents, and happy friends. The atmosphere is festive and bright, with warm lighting and confetti in the air. The girl is wearing a stylish party dress and holding a slice of cake, with sparkles in her eyes and a joyful expression.
Hold an event with the completed visuals
Now that the main visual is complete, I created the design for the event announcement and the venue! This time, I wanted to add a random cheki to the drinks, so I also used sub-visuals to distribute them randomly.
!
I used illustrations in various situations such as goods in the venue, sales, and random distribution!
In particular, I wanted a variety of random distributions, so creating variations with creative AI was a great success!
!!
Up to this point, I have explained how to enjoy it with just a smartphone. However, from here on, it is the professional realm for making creativity a "job."
In fact, in order to develop consistent characters with quality at the corporate level, there is a secret workflow using "Nano Banana Pro," which is also explained in 『AICU Magazine Vol.19』.
In this paid part, I will share the case studies where I actually acquired corporate projects such as overseas expeditions and SusHiTech Tokyo, the specific prompts that made it possible, and the techniques for mass-producing LINE stamps at breakneck speed without hiding anything.
