Arc System Works are avid supporters of the Nintendo eShop. So far, they’ve released games like Family Tennis 3D and Freecell (both out in the U.S.) and Japan-only titles like Family Go-Kart Racing 3D and a port of visual novel True Remembrance.
Arc System Works’ next eShop title is apparently a big enough deal for them to tease its announcement in advance. They recently put up a teaser website for the game with the mysterious image above. The kanji characters in the image mention a girl and an old school building.
No details regarding the game have been announced, but we’ll keep an eye out for more information.
