After its evolution, Fenrir learned that it now was a female, no longer being the genderless monster it was in the past. As a result, she was 'forced' to wear very uncomfortable and restrictive clothing but, as she would learn later, this could also be very useful. Fenrir's Master seemed to like 'cute' thing and, since he would always brush Fenrir's hair and fur, Fenrir started trying to look cute for him. After all, wearing frilly clothing and getting praised by other people made Fenrir feel a ticklish feeling in her heart that she never experienced before.
Of course, Fenrir wasn't always just dressing up and getting pampered by her Master, she was also becoming much stronger. Just as her Master had promised, Fenrir was now much stronger than when she was a lowly and pathetic Kobold...
Now, she had claws that could tear through anything and, as a result of her [Insatiable Hunger], which allowed her to convert anything she ate into energy, and her [Devour], which allowed her to eat anything, Fenrir now had the tools to become even stronger. Her favorite thing to do, other than getting brushed by her Master, was to tear apart lots and lots of monsters, eating their limbs and devouring their cores without end. If not for her Master stopping her, Fenrir felt like she could have kept eating forever and ever...
The most important change in her life, other than the physical changes and becoming stronger, was that Fenrir was no longer lonely anymore. Even when she was a 'bad' girl, her Master always showed patience and tried to help her overcome the hunger that constantly threatened to overwhelm her. She could see that he was worried about her and, wanting to make him happy, Fenrir tried really really hard to learn to control the hunger.
One day, when the hunger got really bad, Fenrir saw something that had heavily impacted her heart. Her Master approached her when she was 'really' hungry and Fenrir had a very strong urge to eat him up. The only thing that kept her from doing so was the strong bond she always felt between her and her Master. Then, when she saw him begin hurting himself, Fenrir began to panic and the hunger suddenly became less important. She didn't want to see him hurt himself and, knowing he did it to help her calm down, Fenrir swore to her heart that she would become a 'good' girl for her Master...
Being 'good' wasn't easy, and Fenrir constantly had to remind herself what she should and shouldn't do. She learned that cutting things up with her claws was 'bad', so Fenrir did her best to step lightly, even though it was very difficult. She also learned that, while baths were scary when given by the scary woman, they were very pleasant when her Master washed her body. Whenever she would be covered in blood, something Fenrir found very exciting, her Master would carefully clean her fur and wipe down her body. It made Fenrir feel a tight feeling in her lower body, especially when her Master would clean around the base of her tail...
