Hades, Osiris and Pluto are the girls that need rebalancing the most. Satou even benched them for Kushinada and Buer.

Joking aside, I tried to make Hades work for the longest time, in a team with Hercules (Axe + SS), Satan, Pluto, Osiris and Hades. The first turn, Hercules gets 45 burst from abilities alone (+30 from Axe, +15 from Osiris), so she can burst in about 2 or 3 turns (as she gets DATA too) and apply Def Down. Satan comes along and debuff defenses some more. Pluto helps beating down with Atk Up... Then I had Hades responsible for keeping the team alive, but ended substituting her for Cernunnos. Hades Defense Up is only 2t duratin, 8t CD, opposed to Cernunnos Stackable Def Up every other turn, plus Damage Cut and Cover all alllies.

But... does her 2t Invincibility prevent damage from Agaliarept's ability?
