This is LoRA created for the purpose of adjusting the cuteness of anime characters. It is a specification that increases the childishness in the positive direction, and increases the adultness in the negative direction. The setting range is about -2 to +2. In practice, it should be assumed that it is often used within the range of ±1, or even ±0.3.
By applying this Lora, the character's apparent age will change, but it is not intended to change the age. Among the existing Loras, it is quite close to Moe2Mature. I guess what you're doing is pretty much the same.
It can be used for things other than anime models, but if you use it in the positive direction, the face often becomes distorted.
Since it was originally intended for adjusting cuteness, the parameter is set as the amount of cuteness, but I have also prepared a version "Cute-Mature Slider" that has the same direction as Moe2Mature and Age Slider (plus/minus is opposite). The contents themselves are the same.
*The sample above is from an older version and is darker in the negative direction, but it has been fixed in the public version.
