OK, I guess I lost all the discussion. Well, if the number of omnipotence is growing, I can do the following if you want. 
[list]
 [*]Lead Necrox to find Lilly and Magio so they can go to their home.[/*]
 [*]Make Yuuka use her power to break a boundary so she and Flandre can return to Gensokyo.[/*]
 [*]Let you guys beat Kaguya (not yours, Kael) to her "death" so she screams HELP ME, EIRIIIIIIIN!!!... and then she goes out.[/*]
 [/list]
With that, the only ones that would remain are Stella, Cruxis and Àgnes (that I completely forgot on the IC).
