You can see kuvira and heal her at Kya's Healhouse
Complete Asami blosssom lessons, gather 3000 yuan, and check your room at day time
Complete Opal events too
After these you can proceed with Chakra lessons
I have done all of what what you recommended below, including those from the walkthrough, twice. :)
I cannot seem to find Kuvira to start her route. I saved the game after Kya asked if the guru can take care of her, and then tried all possible ways to find her. Hence why I ask at what level(s) should I find kuvira?
Overall in the game (without a Kuvira path), I went as far in the game as level 15 and I am missing two chakras to finish korra trainings, which I cant move forward. I am stuck with the only hint being, " in your room", and still there is no one there. :)
