Are all strive arcade routes cannon?

Some character routes just don't make sense at all, like the Jack-o endings, if it is cannon what is the in story/cannon explanation for her wanting to hunt nago? The ending of strive shows us that sol and Jack-o are living together happily in a semi-isolated place, why would she go alone? Sol would definitely not let her go alone. And then we see a clone of herself is that even possible?
