Abilities and Powers
Harden body: She can concentrate her stamina to harden certain parts of her body (head, fingers, torso), thus:
 * allowing her to use Matchless Return effectively.
 * making most slashing and piercing attacks against those protected parts useless. However, powerful enough blunt attacks (such as Madan) can still cause damage.

Matchless Return: Her signature move. After hardening her hands, she uses them to slash or stab to pre-emptively counter her opponents' attacks before they can even notice.

Nails: Her nails are sharp enough to punch concrete and break iron, as well as pierce Kyobo who is a bear without too many problems, using them to pierce people and even a manga that Nomura was using to protect his stomach from an attack from her.

Blood Testing: She seems to like to taste different blood when she manages to strike an opponent, and is able to tell that the girl standing next to Satori is actually Satori's sister by licking a bit of her blood.
