The 'fast' dark SSRs are Thanatos and Satan (Thanatos is actually fast, Satan needs AW.) If you don't have those, it's hard to put together a 'fast' dark team ('fast' in quotation 'cos it's slow compared to the meta teams in other elements, but still faster than your regular SR teams.)
Volos is one that I would recommend if you want some DATA. She is also a rage punisher and has the added benefit of having a +5% hp team-wide passive, so when you get better himes and want to retire her, she is still valuable as a sub.
It sounds like you need a burst leader and not team-wide DATA though, in which case Manes is probably the only option. Manes works well if you EX revive on your soul. A little tricky to use well though.
