Angry smoker

Another Touhou crossover, because it really is never enough e.e
OC Brooke is pretty similar to Mokou, both can control fire, smoke, have a very bad temper and could kill someone any moment (especially their target rival). The only 2 differences are that Brooke is not inmortal and she is a NEET (yes, Brooke can be considered a NEET since she doesnt study or has a permanent job D: )
