I just readed the whole raw manga "Toriko-Again Shoujo", but i dont really understand the ending. So i am here to ask if anyone have read it, please let me know the ending meaning? Does Siren leave Shinju for another child in new country? or its the future, Siren is dead in the past? Im dying to know it <3

I know this answer comes to you far too late, but if you still care to know:

At the end he goes to war and dies, the ending is a monologue of her saying summarizing: I know we will never see each other again and a part of me died with you, wherever you are no matter how or when, wait for me and when we finally meet again no one will ever be able to separate us (simultaneously with this monologue you see precisely him in a different era, finding what is in fact "another her" they also have different names, but you can tell it is still them).
