I think I've officially lost the plot.
I have no idea what is happening anymore
Lynn was possessed by Siegfried, became a Futa and fucked many girls, got together with some narcissistic dragon twins and a super masochist whose sword grows the more he suffers.
Lynn joins the Rosen Garden tournament to meet her beloved Brunhilde who saved her previously.
Lynn had a curse that made her look ugly to everyone, the few who could see through it recognized her as identical to Kriemhild.
Lots of chapters, new characters and dicks later.
Giselher, the youngest brother and a Kriemhild siscon reveals he is something akin to a "cursed time traveler", when Siegfried gave Kriemhild the Nibelung ring (a ring that can give someone any wish), and Sieg was killed, Kriemhild took revenge killing everyone and killing herself, she even accepted Attila just to use him to kill everyone.
Giselher wanted to save her from this curse, so he used the Ring himself to save her, but it kept on repeating itself. In his time loops, Giselher followed different paths, meeting, befriending and learning from all these different groups of people that now surround Lynn.
The current loop is the one he feels is the closest to freeing Kriemhild, as she has not died yet, and her desire for revenge was changed into what created Lynn. However, Giselher himself also became a Key to the loop, and just like the Nibelung ring created Lynn from Kriemhild's wishes, Giselher also has an entity forcing his wish, which is now revealing itself.
They need to defeat/kill Giselher to break the loops in this world where Kriemhild did not kill herself to save everyone.

Saying this from memory, so I could have gotten some detail wrong, but I think it's a good enough summary

Thanks for the corrections, seems like I mixed up two different character, to say the truth, I didn't remember this guy at all, but now checking on his design, yeah. Giselher has the opening on his hair, Gunther does not, completely took them as the same person pretty much.
So the above is now fixed.
