I'm coming for this one, too. This new route only trains up skills to +9 once (for Floral Gust, Mamudoon, Bufudyne, and Fire Breath), and does not bother with Susano-o or Odin (just runs MaZiodyne, which, while it is slower, saves 20 minutes of fusing/grinding in Cosmic Egg, more than off-setting the time loss to the two-three bosses that it's relevant against).

After this failed attempt today (mostly my own fault due to trying out untested strats and ending up with Dekaja/Dekunda/Magaon on one demon, oops), I'm confident that it should be at least 15 minutes faster than the old record. More to come soon (TM)!
