This fight is so off. None of them are remotely making eye contact.

maybe they learned kagebushin no jutsu and are doing a four way battle?

I just noticed that the Vivio on the left has a black jacket, like in StrikerS. Evil clones?

The Einhart on the left is so screwed if her opponent really is Sankt Kaiser Vivio, she's like 20+ times stronger than normal Vivio and took a Blaster-3 buffed Nanoha to take down the mighty king.

I'll be in joy if this happens in the game.

although Einhart is missing her face mask (visor?)

looks like evil clones to me... if thats according to the script I think... Vivio(Black) and Einhart(Black) im not sure how yami is written... 闇 and so it is... Yami...

In Gears of Destiny, Einhart fights against Dark Piece Vivio (with Sankt Kaiser-like clothes) and Vivio fights against Einhart.
