Remember Tanaka and his popular TV show Tanaka’s Amazing Commodities? If you watch this program in Shin Megami Tensei: Persona 3 and Persona 4 the "granter of your desires" will sell the protagonist items and a potential social link in Persona 3.
Amusingly, Atlus opened up a net shop featuring Tanaka who is selling the Persona 3 The Movie soundtrack which has two versions of "More Than One Heart" and remixes of "Burn My Dread." The CD costs 3,000 yen and you get a Tanaka sticker as a bonus.
The site also has some items from Persona 3 that Tanaka sells in game on the site. Unfortunately, these are all sold out.
