- "You need change? What is it then? How about a game of Excite QTE?"
- ―Yuji talking to Ryo at You Arcade.
Despite owning the arcade, he doesn't play alot of arcade games so he doesn't tend to update the machines unless his customers tell him about new games. He only set up the business three years ago after a lot of other failed businesses and this is his last chance to succeed as he and his wife are now in debt from the previous failures. One day, he hopes to have paid off all their debts and go travelling around the world with his wife.
If Ryo Hazuki enters You Arcade, and asks Yuji about Mr. Yukawa, he will reveal that Yukawa was at the arcade. Yuji will then give him Yukawa's business card and let him know that there is also something written of the back of it.
When Ryo is searching for the Tattoo Parlor in hope of meeting Charlie Grant, he can go to You Arcade and ask Yuji about it and he will say a tattooed man comes in the arcade all the time. That man is Shingo Murasaki, and once he is at the arcade playing a game with Koji Yabe, Ryo can ask him about it and he'll tell him the location of the parlor if he joins their biker gang.
At You Arcade, when Ryo is supposed to meet Jimmy Yan from Asia Travel Company for his ticket to Hong Kong, Chai ambushes him and they fight. If Ryo successfully defeats Chai, he will rescue a tied up Yuji behind his desk. Yuji will then let him know that Jimmy is one of the Mad Angels.
After saving Yuji, if Ryo enters the arcade and speaks to him, he will thank Ryo for saving him.
