Yuzuki is a third year student with no special ability, average grades, no friends and her hobby is... self-pleasing..., her mother works late that's why I know she started broadcasting and her... caresses...

** Today was a day almost like any other, as soon as she woke up she did her manual work, got dressed and went to school, waiting for it to finish to go back to "caressing", but that day there was something else...

Teacher: attention class, today we will receive a new student from abroad, so please be kind.

The teacher made a sign for you to come in, the rest I leave to you
