That is their name. It is broken down as Watashini Usotsukuna. This person is just an ordinary citizen as long as you don't lie. However, if you tell a lie, they will deliver a single sharp slap and scream "DON'T LIE TO MEEEEE!!" in a rage. After saying it, they return to being a perfectly normal person. No matter what the lie is, if they detect it, they will absolutely slap you and say it. They say nothing other than "DON'T LIE TO MEEEEE!!"; once they finish saying it, they become normal again. They do the same thing no matter how many times you lie. They will slap and scream at anyone who lies to them. Male, 170cm tall, 17 years old.
