Sensui from yu yu hakusho (chapter black) VS gilgamesh and saber from fate/zero or fate/stay night.
both teams bloodlusted.
Sensui rather easily. His speed greatly surpasses both Gil and Saber as he could easily pick off the two before they have any chance to react and his stronger attacks could even overpower an Excaliblast. The Fate team's only chance at a victory would be use of Gae Bolg or Ea, but I highly doubt Sensui's gonna give Gil the time to whip those two out.
