On two occasions in the Kyoukai no Kanata anime franchise, Ayaka disclosed to Mirai how much A.K. (Akihito Kanbara) would pay for her nude photos. The first time was at 16:55 in episode 5 of the main series, but Ayaka's fingers covered most of the pay check so we aren't privy to the modeling fees.
Then Ayaka bargained again in episode 2 of the Mini Theater, but it wasn't helpful that her voice was censored when she spoke of the modeling fees. However, five 10,000 yen notes were shown onscreen.
Are we to take ¥50,000 as the price A.K. is willing to pay for Mirai's nude photos?
