Synopsis
My classmate Natsuna asked me to give a sympathy to a girl named Sumika Hanayashiki.

However, when I entered the room, the city of Tokyo spread out there. Sumika's hobby is pilgrimage to sacred places such as anime and manga. She has been withdrawn for a long time, and she felt like visiting the sanctuary by making full use of Internet Street View and AR technology.

Sumika, who has the ambition to fill her sacred pilgrimage site someday, never comes out of her room and kotatsu. In search of her sanctuary, the pilgrims decide to take off.
