Edit: Yi Zaha is absolutely and completely hilarious HAHAHAHSHSHSHA LOLOLOL. Yi Zaha seems to have anger issues but btw i love the patient-psychiatrist relationship between Yi Zaha and Poison demon (i forgot the doctor's name hayz) ANYWAY absolutely love this story and will continue to observe the progress of Yi Zaha's goal of becoming just a little less crazy demon unlike his prev. life HAHSHAHAHHA
