If Holy Swords were capable of doing that, someone would've mention it already. After all that would make the Holy Sword Longinus caliber.

Unfortunately, i have to say Holy Swords aren't capable of killing Gods.

"Then, a wave hits Loki!

When I looked around to see what happened…..it seemed like Xenovia swung her Durandal. There is a massive amount of aura rising from the holy-sword.

“Victory goes to one who makes the first move.”

Xenovia says that calmly! You act too fast Xenovia! That’s such a head start!

“It seems like it didn’t work. To be expected from a Norse God.”"

But i can't say it'll be remain the same in the future, like in EX Holy Swords get improved through R&D and so on. So maybe not the current Holy Swords but the future Holy Swords.
