There is also the fact that Emet-Selch (due to his sheer power) could not even be contained in the auracite, and that Lahabrea wasn't killed in the conventional way. According to Ishikawa he's in a similar boat to Hades

Actually I'm reading that statement to mean they're not in the same boat - although it may be missing the actual comparison.

Lahabrea wasn't "literally" trapped in auracite but was pulled into the Eye, which functioned the same way and was subsequently destroyed.

The question may be asking about his first defeat in ARR but Ishikawa didn't take it that way.
