Saja

Saja (沙蛇) is one of the Six Ancestors of 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".

Biography
Saja first appears in Part 2 of Monster Girl Quest: Paradox. While Raphaela is showing Luka the alternate Esta in an attempt to sway him to her side, Saja invades the world using a projection of herself. Addressing Luka as "Worldbreaker", she tells him not to listen to Raphaela as the world she promotes is one where people have no free will and are merely slaves to Ilias. Raphaela retorts that Ilias' control is necessary as humans will make the wrong choices if left alone, to which Saja responds that the freedom to make mistakes is necessary for life to have value. They continue arguing in this manner, eventually demanding that Luka listen to them and not the other. Luka has the choice to agree with one of them or remain undecided.
