As you have just read, it is nothing more than the second season of Yuuki Yuuna.
Let's start from the beginning: It all starts with the disappearance and forgetfulness of one of the 6 heroes: Tougou, no one remembered her and it was as if she had been completely erased from that illusory world. We learn that in reality Tougou is in a dimension where only the souls of a few people access, being used as a sacrifice to the gods of fire, being aware of it for having caused the breaking of the wall and trying to atone for his faults.
Being so consumed and marked by this curse Yuuna decides to save her friend as she saves her in the first season.

Once saved, Yuuna is branded in place of Tougou and takes his place as a sacrifice. This brand acts as a real curse consuming its life and if it somehow tries to talk about it, it will be transmitted lightly to other people as well. So Yuuna becomes a real sacrifice, as well as marked throughout the body and soul, the only way to try to break it is to make the Shinkon, a marriage between a hero and the sacred treeYuuna decides to sacrifice herself for the good of all, but at that moment the gods of the world of flames arrive trying to destroy everything and this is where the final battle takes place ____ Tougou fails to save Yuuna and it is at that moment that ALL the souls of the past heroes arrive even that of their friend Gin, thus helping her to save Yuuna. The battle ends with the final transformation of Yuuna with the glove of infinity defeating the gods of the world of flames, thus restoring peace and thus freeing this illusory world and transforming it into a real world with few sources. ▶ Video A fantastic battle both from the point of view of history but also graphically and from the crazy audio department. Final opinions: I really enjoyed this second season and I have a lot of expectations for the next one, of course I will also read the side stories of the previous heroes. ____ HERE'S THE GUIDE TO WATCH YUUKI YUUNA
