Maintaining the Same Character | How to Fix Settings in Text

In the first episode, it was the same character. But by the fifth episode, they become a different person.

When creating characters with AI, you can get a pretty good image if you only need one. The problem is what happens after that. When you try to make a continuation of a manga, a short animation, or a series for social media, the face changes slightly. The hair accessory disappears. The sleeves of the clothes change shape.

I will state the conclusion first. To keep the same character, just asking for "the same character as before" is not enough. You need to fix the elements that shouldn't change into a text format that you can paste every time.

In this article, I won't cover all the tips for character creation, but rather how to create a setting sheet to keep the same character across multiple images and episodes. The goal is not to get a good picture on the first try, but to leave information so that even in the fifth episode, it is clear that it is the same character.

Why they become a different person by the fifth episode

AI does not remember past images like humans do.

Even if you write a similar prompt, it interprets it slightly differently each time. In the first episode, the eyes were round, but next time they look a bit more mature. The clothes are similar, but the shape of the collar or sleeves changes. The hair accessory disappears in one episode.

If you look at one image, it is acceptable.

But in a series, those small differences add up. By the time the reader thinks, "Is this the same character as the first one?" in the fifth episode, they are looking at the differences in the art before the story.

What is needed here is not to make the prompt longer every time.
It is to separate the elements that should not change from the elements that can change.

Fixing elements that should not change in text

The first thing you write in character settings is not personality or worldview.
First, fix the elements that determine it is the same character on screen.

• Facial features

• Hairstyle

• Hair color

• Eye shape and color

• Basic clothing

• Body type and sense of height

• Accessories

• Color combinations

• Art Style Direction

If you leave this vague, the AI will create a plausible average every time.
For example, just saying "a young man with black hair" is not enough. This is because the interpretation of black hair, clothing, and the atmosphere of the scene is too broad.

黒〜ネイビーの短めの少し乱れた髪、落ち着いた青い目、白いTシャツ、濃いネイビーのフーディ、透明な青いホログラムUI。

If you write this much, at least the character's exterior will be more likely to remain consistent.
Furthermore, if you are using it for a series, divide it by body parts.

【顔】
落ち着いた青い目。少し考え込むような表情。顔立ちは細すぎず、やわらかい。

【髪】
黒〜ネイビーの短めの髪。前髪は額に少しかかる。毛先は軽く外へ跳ねる。

【服装】
白いTシャツ。濃いネイビーのフーディ。スポーティすぎず、少し未来感がある。

【小物】
透明な青いホログラムUI。指先の発光パネル。青いデータ画面。

【色】
ネイビー、シアン、白、青い発光、少量の紫。

By keeping it in this format, you can paste it as-is for the next generation.

Decide which elements can be changed

If you fix everything, the image will not have any movement.

In manga and anime, expressions, poses, angles, backgrounds, and lighting need to change. If you fix everything to this extent, the result will look like the same standing illustration with only the angle changed.

Therefore, you should also write down the "elements that can be changed" in your setting sheet.

Things that do not change:

• Facial proportions

• Hairstyle

• Hair color

• Basic clothing

• Accessories

• Color temperature

Things that can be changed:

• Expressions

• Hand positions

• Body orientation

• Camera distance

• Background

• Time of day

• Light intensity

Without these boundaries, the AI will either fix everything too rigidly or change everything freely.
For example, these instructions are easy to use for a series.

以下のキャラクター設定は変えない。
表情、ポーズ、背景、カメラ距離だけを場面に合わせて変える。
服装、小物、髪型、顔の比率は維持する。

Writing this much makes it easier to request 'the same character in a different scene'.

Small items are the most easily forgotten

Small items are particularly prone to being dropped in a series.

Even if the hairstyle and clothing remain, bags, hair accessories, glasses, pens, and neck accessories tend to disappear. The reason is that they are often treated as information with lower priority than the character itself.

However, readers sometimes judge that it is the same character based on these small items.

Blue hologram.
Glowing panel on the fingertip.
Dark navy hoodie.
Color difference from the white T-shirt.

If these disappear, it looks like a different shot even if the face is similar.
If you want to keep small items, just listing them is not enough. Write down their roles as well.

透明な青いホログラムUIを必ず手元に置く。
濃いネイビーのフーディと白いTシャツは、このキャラクターを識別するための固定要素として扱う。

Instead of 'small items that would be nice to have,' make them 'fixed small items to identify the same character.'

This is the most effective part of this setting sheet.

If you continue with the same character, carry over the settings into the conversation

If you create each image on a separate screen, you need to copy the setting sheet every time. That is sufficient for short tests.

However, if you are creating multiple pages of a manga or a short animation of the same character in succession, it is easier to carry over the settings within the conversation.

If you use CrePal here, it is better to use it in a way that increases scenes while keeping the character settings, rather than generating single images.

CrePal handles materials, scenes, generation, subtitles, audio, and export in the same flow as a video production agent-type workflow. When creating different cuts with the same character, the advantage is that you can carry over the settings you want to fix while conversing with it, saying 'use the same character as before.' Of course, since the free tier, watermarks, commercial use, and export conditions change, please check the latest screen before using.

The key points are the same, not just for CrePal.

Treat character settings not as a one-time prompt, but as information to be passed on to the next cut.

If you can do this, you can reduce the probability of them becoming a different person by the fifth episode.

First, fix the exterior, not the worldview.

When creating a character, you want to start with their personality or story.

Cheerful personality.
A bit clumsy.
Close to the reader.

Of course, that is important. However, in the practical work of maintaining the same character with AI, what is needed first is the exterior.

Face.
Hair.
Clothes.
Colors.
Accessories.

If this is not preserved, even if the personality is the same, the reader will see them as a different person.
What you create first is not a completed profile.
It is a setting sheet that you can paste again next time.
Whether they look like the same child in the fifth episode is largely determined by the text before you release the first episode.
