Persona 5 Royal has many side activities. Many of these are only unlocked after hours of playing. One of the additional activities is part-time work. The Triple 7 convenience store is one of them. In this place you can earn money and increase your Charm. Thanks to this article you will learn about Triple Seven and barcodes.

To apply for a job at Triple Seven in Persona 5 Royal you need to go to Shibuya, specifically the Underground Walkway. Now go to a newspaper stand with a sign that says "Best work". Interact with it and after a short conversation you will become an employee.

To get to the Triple 7 convenience store you have to go to Shibuya Central Street. The shop is located opposite the Burger shop and next to the Arcade. It is marked with the number “24” on the map.
Working at Triple 7 in Persona 5 Royal will, of course, allow you to earn money. However, there is an additional bonus. This job will also increase your Charm. It is best to work in this convenience store on days ending in the number 7. You will then get much better rewards.
Being an employee at Triple 7 is also the only way to unlock the Calling for Justice for Cats request. This is one of the tasks you can do in Mementos. You have to work a few shifts there (2 or 3). If you do this, Mishima will eventually contact you and assign this mission.
An additional bonus of working at Triple Seven is that you may be visited by various Confidants. Meeting them will be rewarded with +1 point to Rank.
