Guys, let's prepare for the worst....
I reread chapter 97 and found very strong similarities between the original god of Chaos and Loki, he also uses chains in battle and has marks on his palm, not to mention that the upper part of his clothes is very similar to Loki's design.
Ymir is 100% Zeus who only uses hand-to-hand combat and we all know very well that he can turn into a muscular giant.
I highly doubt that the author will not use the chance to resurrect Yggdrasill, probably Odin will use plan B if Siegfried is unavailable and use Zeus, Loki and Beelzebub as a vessel to return the originals to the world.
And you know what will unite all three? That's right, they killed the most symbolic Einherjar - Adam, Tesla and now Loki is fighting Simo. We wanted an unpredictable 50/50 match, but it seems the author clearly tried in these chapters to make sure we knew who should actually win.
Goodbye Simo... I hope you at least save the Valkyrie and your dog(((
