A few kilometers outside the Battle Maiden Sect's Core Disciple Court, a tall woman with auburn hair and red eyes at the 3rd Stage of the Soul Transformation Realm faced off against a Mid-Stage Rank 8 Cougar. 

Although it was a Rank 8 beast and could transform into a humanoid form, most beasts never even considered doing something like that. There are several reasons for this, but the number one reason is pride. They were born a beast, spent their life as a beast, and didn't see a need to conform to human society. 

However, there are other more practical reasons, such as most beasts' life's worth of combat experience is in their beast form. Fighting and living in their humanoid form would be going against all the experiences they've built up over their entire lives, along with their natural instincts.
