AW V21 stuff.

Metatron can only control up to Beast-class Enemies,anything above that rank is beyond her abillity to control unless they're from Contrary Cathedral in which case she has control over them.
Oscillatory Universe's EK plan:
1.Orchid Oracle uses Paradigm Breakdown to bring everyone to the UNF thereby temporarily negating the Territory Battle.
2.Glacier Behemoth traps the NN members using his IS skill Last Glacial Period and Snow Fairy EK'ing them using Brinicle,while Ivory Tower prevents any attempt of them using IS Skills to break out of the EK using Imaginary Time.
3.Repeat EK until everyone is dead(if anyone somehow escapes Brinicle+Last Glacial Period+Imaginary Time combo the other members of OU like Cloaker and Milady hunts them down and EK them).
It's revealed that that the members of Oscillatory Universe is aware that the ARS are the inner circle of the Legion and are working together with them willingly,also the non-ARS members like Shadow Cloaker doesn't have BIC on them.
Orchid Oracle doesn't know that Falcon and Blossom(the most important person in her life even more than Kuroyukihime) died because of Cosmos and after a talk with Blossom's backup backstabs the ARS by using Paradigm Restoration to undo Paradigm Breakdown
It's hinted by Glacier Behemoth that Oscillatory Universe knows that the Fluctuating Light is the reason why AA,BB,and CC were created and refers to it as a curse older than Chrome Disaster and the ISS Kit,also Rose Milady mentioned that OU's goal is to bring about an end and a beginning.
The cane Ivory Tower has is actually the Luminary loaned from Cosmos(whose Luminary form is 99% likely to be the Throne seen in the AW games and Millenium Twilight unless Reki changes his mind)it's abillity is to create silver crowns to control Enemies,it looks like a cane when Tower/Vise is using it because the Seven Arcs(minus The Fluctuating Light who is actually a person and not weapon) changes form depending on who is using them.The Luminary was returned to Cosmos because Bell used Citron Call Mode 2 to reverse Tower's time to before the Luminary was loaned to him,this also has the effect of undoing his control over the Devil Enemies he controlled using it which resulted in him killed by them.
Ivory Tower has the abillity to negate IS skills using his own IS skill Imaginary Time,the downside is that the range is limited to anyone near him so he has to also be continually killed by Snow Fairy for the trap to work.also he can use his alternate form's abillities Shadow Lurker,Static Pressure,Layered Armor,Hexahedral Compression,Octahedral Isolation in his Tower form altough he will turn into Vise shortly after using one of his alternate form's abillities.
Paradigm Breakdown isn't a go to the UNF free ticket IS Skill,all it does is bring anyone from a local duel into the UNF and no one can go beyond a 2km radius of where Oracle used Breakdown and the area is isolated from the rest of the UNF.
Megumi regained Brain Burst a short time before the Territory War happened in the school library.
