The game is about a young stock trader named Shun Aiba. Shun's father was a trader who went bankrupt and disappeared when he was 13. Five years later, you are summoned by your father's former trading partner, Toru Narasaki, who wishes to teach you the tricks of the trade. Shun is joined by Hanako Kirikagura, the daughter of a family of entrepreneurs and Toru's pupil. The gameplay is split into two parts: adventure and trading. Adventure mode is apparently much like Capcom's Ace Attorney series, where Shun travels around town furthering the story. Trading mode consists of Shun battling against rival traders, earning a set amount of money, or trading with an AI partner. Shun can purchase or gain Trading Arts to increase his skills in this mode. from wikipedia
