These two are going to have the most ruthless fight ever (ignore übel).
I know the whole wherlos/eisen deal kinda bilnded people of the actual peak fight that stark will have in the arc. To be clear, I'm not saying he will not fight wherlos, but i don't think he will be the main fight for him either.
Schritt, on the other hand, has some striking parallels with stark with the whole hands shaking if she doesn't drink before a fight, plus her being a redhead just like stark may be a hint of them being related somehow maybe same clan or even from his village.
Just think about it. Stark clearly suffers from survivor guilt since he abandoned his village that day, so her being another survivor of rivale's assault opens up a very interesting thread for stark as a character to progress, more Stoltz and we may get some lore about the reason rivale attacked the village. I think it also matches chronologicaly? with gorilla starting his journey, so maybe he found her and then became known as siblings.
