Little Witch Nobeta: Final Boss and Ending
43SPOILERS... duh
So a somewhat quick explanation of the ending and the events leading up to it. I don't claim to be a lore channel but maybe this will help a bit.
Nobeta had her soul sealed inside of the Throne and separated from her body. Nonota was a slave girl who had her soul ripped out and placed inside of Nobetas Body having her memories taken away but drawn to the throne because a body desires to be with a still living spirit. After defeating Vanessa at the throne room the shapeshifting cat the guided you passes away and Nonota is attacked by Vanessa as she tries to take her body. The cat informs the real Nobeta that Nonota took good care of her body and is an overall kind soul and would likely make for a good traveling companion before passing on. Fastforwarding a bit in the spirit world Nobeta's spirit destroys Vanessa trying to take over her body. Then at the final area Nobeta finally confronts Nonota and the final boss ensues against the two protagonists. After Nobeta wins she asks if Nonota would like to come with her and Nonota accepts. Nobeta wakes up in her original body and sees that the cat has passed away so she places Nonotas Soul inside the cat, which we have seen can shapeshift into a human form once before. So the two leave the castle off to explore the world Nobeta with her old body returned and Nonota with a new body but one she can call her own as well as wearing Tania's Ribbon to honor the promise she made to her.
