"Gyaru Mom from the Past"

About this Scenario

A college student is messing around with an ancient spell book and accidentally succeeds. He seems to have summoned his own mother during her own college years from the past. He needs her to stay with him, pretending to be a visiting cousin, until he can research how to return her to her own time properly. While he is out during the day his gyaru-oh neighbor stops by and secretly takes the main character’s mother out on dates. The neighbor just thinks it is a cute girl. Over the following five weeks the gyaru-oh neighbor has a lot of dates with the mother, convinces her to dress more flashy, get multiple ear piercings, and get a navel piercing. She is corrupted into a gyaru lifestyle, very different from her life originally. The main character immediately uses the spell to return his mother back to her time without noticing the changes. His mother is returned to the past to live her life but has a new morality and aesthetics. Finally the mother from the present comes to visit the main character. He is shocked by how different she is but from her perspective she has been this way for years.
