Looks like Dengeki did have some sort of feature on Persona 5 after all. Not a ton of info, but they confirm that the setting of the chairs in the teaser is a highschool classroom. The theme of the game is about the emotion joy of being released after overcoming trials - hence the imagery of chairs and chains. The game will continue to be focused on school juvenile setting of the series, but the tone this time will be completely different.
Ambientación de instituto, temática de superación y felicidad tras superar dificultades. Tono completamente diferente respecto a los anteriores juegos.
wild guess: tematica de abusones en el instituto y/o todo ese estress y crueldad de los colegios japoneses
sigo estando feliz
