Black Magic is the dangerous aspect of magic that deals with exercise and energy. Depending on the physical phenomena handled, it is divided into five lines of "active / fluid system" "acceleration / weighting system" "time / space system" "vibration / wave system" "focusing / diffusion system".
The basis in which Black Magic produces attack spells includes Fire, heat, cold and electricity. Black magic "activity / flow system" is a field that manipulates this. These three attributes are more efficient when converting magical power to physical acting force (material force) than other attributes, and in "Tsizer 's three genus ratio" against 10 magical powers, flame heat: cold air: electric shock = about 8.5: A theoretical maximum value of 7.9: 8.2 is obtained.
