Rin asked, "Who are you and what is your business with me?" ,the girl didn't answer immediately but eventually ,She spoke "I need someone to introduce me to the system and everything in the school". Rin replied in cold tone "ask someone else". The girl hesitated and said "everyone is staring at me from the point ,I entered the school and everyone started staring at me ,It is kind of uncomfortable". Rin asked "what does it have to do with me" ,the girl with pleasant smile replied "you didn't even paid attention to me when you entered the class ,so I thought you might be a good option then others". Rin sighed and said "ok ,come with me" ,Rin explained every details and rules to follow in the school and he asked "so ,what is your name" ,The girl replied "OH ,so after this much time you had some respect to ask my name".
Rin didn't react or replied ,the girl eventually spoke "My name is Yuri".
Then Rin with a cold eyes and cold tone said "so ,the government send you to spy me ,ha" ,the girl didn't react either and she spoke "so you real are smart as the rumour says". The girl spoke "The government see you as a potential threat ,but to me you are just a insolent and arrogant brat".

The story of how the world was created was a fake story to make the people believe the government.
