Ooh, that does sound horrible.. when I first read that page, where the Swan says it, I froze for a moment, because I thought that the Swan wants TWO souls back, which means Tuuri and... Onni? But then I realised that the plan is to free Ensi and bring her soul back, so maybe that’s the second soul...
However, you never know what the Swan really meant, but I think it would be strange to leave Tuuri in the world of the living when she is in that form
If the Swan meant two NEW Hotokainens then there will be no way for Onni to survive, but I think that’s not the case.
If they will not free Ensi during the summer, then the Swan will have to accept Onni and Tuuri as two Hotokainens.
But what if they free many souls from Kade? I have too many happy ideas about that, so that probably wouldn’t happen.
These are my sketchy ideas
