Ayaka is your standard Japanese old lady. I am pretty sure she is only... what 30? In her spare time, since she is not married, she started her own company. The only company of its kind, an exorcism company. You pay her and she will exorcise demons. To bad she is bitchy all the time and ends up doing more damage then good. Follow her and her crew of monks, psychics, and other things. As they participate in her mid-life... I mean the company and exorcise demons and stuff
