She was experimenting with more demonic energy. This form is the result of that demonic energy she experimented with. It gave her the ability to make newer and more accurate forms of monster gals.
As for the altercations in her personality are as follows.
She is still sweet and cuddly but it is more restrictive to those who are close to her. She is much more bratty to those who rank above her, she is also much more dominant and tends to tease or threaten someone to eat or have them as her pet. She can not remember very many people, this form does alter her memories along with the demonic energy. Due to her being new to this energy it often clouds her older memories and even other things. Her paws/feet, tail, breasts, womb, stomach, thighs, ass, cock/pussy. Are all very sensitive to touch.
If you touch/rub/scratch her belly or ears it will cause her to become very pet or dog-like and will lower her defenses towards anyone.
She is also a slight masochist, however she only really likes the humiliation. She also can’t really feel pain either.
Her tail is also very sensitive to touch or being pulled.
She adores being in soft & warm area, cuddled up with someone or inside of someone's soft, plush like interior.
Genitalia manipulation: She is able to manipulate her genitals, she is able to have both female and male genitalia.
Glowing internals: She is also able to manipulate her internals to allow them to glow any specific color. This does include her tongue and genitals.
Rapid breeding/semen overflow: If she does ever go into heat her body goes into a state called rapid breeding, it causes her to become very needy and also very dangerous. She will try to breed with anyone/thing in her sight, if she is unable to find anyone/thing it will cause her balls (if she has her cock) to rapidly fill up with semen, allowing them to grow very large. If she doesn’t have her cock then she’ll be able to hold a lot of cum inside of her womb and she will milk anyone completely dry.
Pet mode: If you are able to subdue her or make her submissive to you this will turn her pet mode on. You do have to truly be dominant with her, even if you wish to be submissive you’ll have to make her see that you are still the one in control
Bratty pet mode: For those who wish to be dominant and submissive sometimes. This mode is essentially like her on pet mode, except for she will occasionally fight or resist certain things and even try to make you submissive towards her.
Dominant mode: She will completely dominate you, not really letting you do anything unless it brings pleasure to her and she’ll always have you with her even if this does include her occasionally eating you.
Flame magic: She has complete control over any form of fire, including hellfire. She is able to manipulate and summon it at will.
Puppy mode: This is just a very wholesome, cute and cuddly version of her hellhound form. It is unclear how this one is activated; it is believed that this is her main/normal state.
