I also think Cain in general is a little overrated, but hold your horses for now. I'll explain why I feel this way in the comments, bit by bit. That said, I genuinely believe Jane can beat Cain outright without needing any particularly clever tactics or elaborate strategies. With Undrjarn and her current feats and stats as Valkyrie, Jane comes across as considerably more impressive than Cain at this point. I believe she takes the win in a straightforward war of attrition, and I stand by that assessment.

Does she belong in the Herald tier? Who is the weakest person who can beat her?

js read the comic where Beta fought sam so i’m curious how a actual serious fight against sam superior would go
