Ren Amamiya, a Special App

Ren Amamiya, the leader of the Phantom Thieves, was used to strange apps. It was an app which allowed him to enter the Metaverse and steal hearts, after all, but this app seemed even stranger. He had found it on his phone with no explanation, much like the Meta-Nav, but this app was called 'Custom Girls'.

Ren wondered what exactly he could do with the app, and so he called up one of his female friends.
