Ketsui has unwavering determination and resolve. She's not afraid to stand her ground against tokotas and other creatures much larger than herself. As such, she can be difficult to handle from an owner's prespective. While she may lean towards using aggressive acts and threats to get her way, it is rare for her to actually harm anyone beyond a well-placed nip or bite. That said, should the receiver of her warning fail to back down, she's not opposed to using violence.
