I'm not real knowledgeable of DNC and cant read jaoanese. It seems like you put a couple steps on him and then 3 stepped darkness. Mind translating a little there Konvict?
From what I can tell:
1. DNC/SAM, box steps (lowers def)
2. fan dance+poison potion or similar
3. meditate+sekkanoki -> evis->pyrrhic kleios -> darkness
4. Grand Pas (DNC SP2)->Reverse Flourish (i think climatic flourish too around here)->Rudras-> double dark.
Might've missed something, I'm not sure. You can do this without /SAM too (double dark that is) btw, tp to 1k->SP2->evis->rev. flourish->PK->rev. -> climatic-> rudras.
