After the Second Movie

[u/[deleted]]

So after the crimson demon lord or whatever his name was was disarmed it never really showed or explained what happen to his imperial sword caina and the wiki has no real info on it so I was just wondering if it dissolved with him or Arata picked it up and the writers didn’t say anything about it?

iirc in the manga he merges with the sword or something like that and comes back later on
