Saja

Saja (沙蛇) is one of the Six Ancestors, of the Lamia and Harpy bloodline, with their genes mixed within her body. She boasts an arrogant nature and is very clingy and relentless to males she likes and won't be satisfied until she makes him into her sexual slave. There is an unconfirmed theory that she might be the second monster lord.

In Paradox Chapter 1, Promestein refers her as "a snake type monster who looks like Alice".
