Elena

"Your mother, Elena, has been missing for many years, I'm afraid she might have passed away."'

- Ferdinand to Sofia/Lilina

Elena (or Irina) was the previous wife of the Empire's King Radler. She's also the mother of Sofia. She disaperead a long time ago...

In the Beast Lady Line, we discover that Irina is alive : she became a Beast Lady and serve Divine Beasts as a cum dumpster. She say that Feldt charmed her to send her to the Beast Land. Here, she met Barrock who submited her with a special Crown. Irina almost lost totally her mind. Divine Beasts claimed her and she become a cum dumpster. That said, a small fragment of her soul remained and she regain consciousness when she met her daughter. she explained her everything and also how to use the Beast Lady state as a transormation and how to escape.

However, this small fragment now fainted and she's condemned to be a cum dumpster forever.

If Sofia become a Queen Beast, she will be the one who will reward her and give her limbs back.

According to Ferdinand, when he explain his plan to bring back Arianna, all Princess who become Spirit Witch will transform to have the same body, probably because of the magic device who contain Arianna's soul fragment. This explain why Elena and Sofia have the same body.
