Hild is the ruler of Niflheim, with power equal to Kami-sama.  

Where in the manga does it say her power is equal to that of Kami-sama?

It doesn't - but Belldandy as a Goddess First Class wears a single earring 
limiter in order to bind her powers - which - if let loose could destroy 
the world.  Hild wears more jewelry than all the other goddesses combined 
by a factor of ten or so.  Hild's minature 1/1000'th form (which is 
actually quite large - the size and appearance of a child) is still more 
powerful than a full-manifestation of a Goddess.

Hild refuses to use full-powered spells because she's afraid of the 
damage (of killing a Goddess).  She creates a transportation (or was it 
warding?) mandala in seconds - while it takes the Norns hours to create a 
similar one...

Hild's teleportation from hell had to be specially shielded by her so as
not to wipe the village she was teleporting to off of the face of the
planet due to residual discharges...

Need any more proof?
