Sanakia Drelshkaf

Rance IV
Sanakia first appeared in Rance 4. She was a knight from the ancient kingdom of Dallas. When searching the floating city of Irapu, she was captured and frozen for a long time by a mad doctor. When she was about to be transformed by the doctor, Rance slays the doctor and rapes her while she wasn't conscious. Because of it, Sanakia hates Rance and leaves. When the floating city of Irapu falls to the ground in the end of Rance 4, Sanakia escapes from the crash and set out an adventure alone since her country (Dallas kingdom) was gone long time ago.

Kichikuou Rance
After the event of Rance 4, Sanakia settles on the ruins of the fallen city of Irapu. She became the military leader of local city. When Rance's army attacks her city, she is defeated by Rance and raped again.

(*Since Kichikuou Rance is not approved as an official storyline, so this really didn't happen.)

Rance VI
After the event of Rance 4, Sanakia travels to Zeth kingdom. When she saw the slavery of non-magic users in Zeth, she joins the resistance Ice Flame.

When Rance joins the Ice Flame, she first conflicts with Rance. But in the later part of Rance 6, she expects to be a Rance's knight when Rance promised to make her the leader of the knights when Rance becomes the king of zeth.

However, Rance forgets about the promise and went to JAPAN....

Sengoku Rance
In Sengoku Rance, there is an event that Sanakia complains why Rance didn't keep the promise. This is just through dialog and Sanakia doesn't appear in-game.
