She also runs the Prisons and is the head of the Intelligence. And if I'm not mistaken, Vi the only one of the sisters who is Kiyomi's most capable student and can stand up for herself. Of course, she's still a long way from Kiyomi's level of fighting prowess, but our reserved and somewhat shy scientist can easily wring the neck of just about anyone, even without the help of her subordinates, Kiyomi and Deadly Vipers.
