Okay people, I don’t know if this was thought of before but I just came up with two theories on how kuernai himejima was able to create ex gremory’s (I think it was meant to be ixis because that’s was it said in the first spoiler of the highschool dxd ex short series) artificial longinus, boosted gear diabolos.

1- kuernai used one of the red versions issei’s of dividing wyvern fairies to make his sacred gear (like how issei and rias were able to make her own scale mail armor from syncing his red wyverns with her aura).

Or

2-kuernai created his own version of the boosted gear gauntlet, only instead of using multiple dragon souls like euclid lucifuge did, he used the soul of his father’s retainer, bova tannin aka bova the destroyer, as a power source(I think this is possible because due to bova being such a devoted follower of issei he would do anything for him even protect kids, as for how the gauntlet would get the power to boost, perhaps bova learned that ability later on from fighting alongside issei, or the gauntlet channels ex’s natural ability to boost his power, which is said within to story by azazel to be an ability all his siblings have inherited from their father).

What do guys think of these theories, and which one do you think is more likely? I especiallywant the admins opinions.
