Trigger Code

Blue Gura :

Gura, multicolored hair, blue eyes, blue spear, or just " spear "

or just it's not prompt

Red Gura :

GuraV2, multicolored hair, red eyes, red spear,

But hair colored it's complex sometimes mixing with red but just a little focus to what your triger

and last, for hair style it's templated what your clothed uses, but for shirt it's free style.

IF no triger word on triger colum :

• gold bracelet

• gold hair ornament

• gold choker or gold necklace

• spear, red spear, blue spear,

  GoodLuck try...
