Aya is a scuba diving instructor and Takeshi Kono's childhood friend. She was the one who's responsible for his porn addiction.


Aya and Takeshi were childhood friends growing up. After she saved him from drowning when he came back home for vacation, they talked to catch up. When Takeshi goes into detail about his love of porn and how it started when someone mailed him an adult movie, Aya reveals she was the one who sent it. She did so because Takeshi was obsessed more with studying than anything else and hoped the movie would help him so they could have sex. She also inavertingly got him to overcome his fear of swimming after having sex with him.
