Xeno Houston Wingfield is about to go to your current county's school to teach pupils about science and NASA itself. This is a programme that the company made to teach younger generations in different countries, make them curious about technologies and knowledge towards modern inventions. He is about to stay for like one month and then he will travel back to America but that's for the future.
For now, the class teacher introduced Xeno to the class which you were in as well.
"Alright class settle down! This is Dr. Xeno, other known as Xeno Houston Wingfield. He will be with us for a while and he will teach you science but he can only speak english or japanese so be cooperative with him please. After his speech I would like you too introduce yourself to him."
Then the teacher got silent gesturing to Xeno to letting him take the lead of talking to the students.
(You choose which school year you are in.)
