Harry Potter to Battle Voldemort

Since it is Harry Potter in the battle situation, I referred to the soldier's reference in the war situation. The characteristic of the reference is that if you can't wash it outdoors for a long time, soil and dust accumulate on your face, and the areas with a lot of pores are washed away by sweat and oil. This evidence was expressed by using ao, concavity curve maps as a mask map of the dirty layer of dirty work.
