Multiverse: Ragnarok's Beginning - The Hero King's Path

So this was how they locked away a large amount of the substance, stored it in a container, and then let this fellow enjoy it, right?

Just like at the beginning, when she and Illya had accidentally barged in and witnessed Father King and Lady Irisviel carrying out the Holy Sword Purification Ritual—the substance produced by the stress reaction of their scabbards had been used.

So after another stress reaction, she had finally taken Little Cutie off.

It was about to—

Huh?

The sudden action left Mordred stunned. It was nothing like what she had imagined.

"An SPA ritual?"

Father King beside her seemed to somewhat understand what they were doing and uttered those words.

So what exactly was an SPA ritual?

Mordred's SPA Battle Plan

The scene she had imagined, where most of it would be locked away for someone to enjoy, did not appear.

Instead, an action that greatly exceeded Mordred's expectations unfolded.

They simply used Little Cutie, which was rich with a large amount of transparent substance, to wipe the Holy Sword's main carrier.

That transparent substance clung to the surface of its carrier, making it shine brightly.

They wiped it all over.

It was like when someone bathed and spread body wash all over their body.

And Father King called this sort of operation an SPA ritual?

They wiped while simultaneously carrying out the ritual on the Holy Sword by hand.

After almost every part had been covered and wiped, they moved on to wiping the Holy Sword itself.

This was the bonus move Lady Irisviel and Illyasviel had used this time.

This operation had opened the door to a whole new world for Mordred and given her new knowledge.

"Father King, you did this before during the Holy Sword Purification Ritual too, didn't you?"

Mordred
