Are you not familiar with how "Visions" work?

We don't know whether she died or not, we didn't see it tho in the story.

Yes, she died way earlier on and so is Owe halfway through the story. Some characters appear in your roster because they are visions and being summoned back to life by your good self.

Visions disregard time and space, there needs only be intense memory or emotion or convoluted magic. It's why we can summon Fina, who's from present day FFBE (way in the future), and Cid, someone not even in the world of Lapis

Yes that is what we know so far in the story but is that true? Everyone thinks Helena died but she survived in the story, so my theory is that she might not be dead as the story progress. Which means schuzelt will have a surprise in store
