Again, I am not translating the speech bubble, google translate is over there you lazy ass gringo!!!!

But, i'am I explaining her name!! Is basically a junction between two words that mean the same "Ke" being from the language spoken from the Guarani folk here in Brazil and "Sonnar" Being an ancient form of the world "Dormir" from Portuguese.

The two words means in itself sleep, dream etc.

So you could interpret her name as “Sleep and dreams”
