The difference between ota (Enemy) and aseni (Personal Evil Doer)

There is a difference between ota and aseni,

Wait, what is the English of Aseni? (Personal evil doer...uhn?)

Anyways, According to research,  Ota lives at your backyard while aseni lives with you in the house and gives ota clues about what goes on with you in the house.

Ota is anybody that don't wish you well while asheni is a person who's finds his or her purpose to destroy and make you unhappy.e.g its just like someone going to pry sch wit you,secondary and tetiary just to get close to you and destroy you and not for the certificate.
Ota are beefers mostly that act on the beef,but asheni lives for it,they go all the way.
