Hmm. I was rereading that part and I think there's a part where maybe all of us misunderstood.

"But if you were to group them, there are four types of [Absorption Line], [Blaze Black Flare], [Delete Field], and [Shadow Prison]. These Sacred Gears were hidden with each possessor with somewhat differences. And our organisation, Grigori, retrieved them and put the Vritra-type Sacred Gears that we kept into Saji-kun."

Meaning, there are 16 Vritra Sacred Gears in total and all of them are in Saji's.

~Anyway... Discuss.
