Maze Rune 105

I've done Moblin Maze Mongers more times than I can count, and while I don't have every rune, there's information online about most of them.
From Aquans to Magic Bursts, from Rune 001 to Rune 119 the only one that no one can find any information on or even prove the existence of, is Maze Rune 105.

Does Maze Rune 105 exist? Is it even in the game?
And if it doesn't exist, why skip that particular number? Will the elusive Rune be added before the final update? Of all the dropped content in the past, why leave out that one rune?

There are a bunch of runes that don't exist. Believe me, I've been through the exact same questions you have. NONE of the job runes beyond the original 6 were implemented, so that's runes #57-70. Additionally, only Healing/Enhancing/Enfeebling/Elemental/Divine/Dark Magic were implemented, so no to runes #47-50. I just have no idea what #105 was intended to be, but it simply does not exist.
