Search of original costume. (Dead or Alive 5: Last Round)

Pumped recently the latest build, played-glad the costumes were very happy with the costume Cassano, but the execution not so much, and without a helmet would be nicer... In General, Hayato has a suit this is the same as in the picture. It's part of the last Hallowen set. I thought that the character of any Studio, but after learning what he's all depressed, but still not losing hope. Please tell me, who represents/symbolizes/is a parody of this suit, or at least where it came from, some percoidei, maybe it's the interpretation of the spirit of some of the the habaneras?! Not like he's on something taken from the ceiling, these things belong to the dark universe, and Aragami is very similar. Thank you for your attention. I will appreciate any theories
