Though it was hard to believe, Diya indeed had the highest demand for strength; her "Aquatic Line" Miracle was an extension of the Fist Claw Faction, fundamentally requiring immense power. This was contrary to Ash and Sonia, whose swordsmanship focused more on skill and speed, so Diya took the "Ogre Gloves."
"Technique Spirit Coffin" could be handled by anyone, but considering Ash had blatantly favored the Sword Maiden under everyone's watch, he let Weiser take the collection.
Drinking two potions from the Lightless Sanctuary allowed Ash and Weiser to consume Magic Power to congeal the Holy Domain. However, it was different from Technique Spirits and Miracles; the Lightless Sanctuary was like a black box—Ash couldn't comprehend its functioning principle and only knew that inputting Magic Power could raise the Holy Domain.
Unless they later entered the Space Faction, the Holy Domain could only remain at this preliminary stage.
