"Burst Into Tears"

After all, Ainsley used to be cold-blooded and strange after she ended a fight that involved blood. 

Furry cats are needed to restore Ainsley to her usual bubbly and cute self. 

Indeed, after the OP cats meowed, rubbed their heads on Ainsley's leg and acted like spoiled children, the baby's aura slowly turned gentler than before. 

During the battle, her aura was sharp and cold, just like her teacher, the Godfather. 

But after the battle, the baby slowly turned into her cute self that could charm people from miles away. 

Zach and Leah saw all of this, and both of them almost cracked their usually cold expressions. 

...drinking milk after a bloody fight...and then playing with cats...

One wouldn't associate the current Ainsley with the Ainsley who had just severed a person's arm. 

They didn't know that a human cub could be this weird...
