Goblin slayer reacts to the past (not a story but an idea)

The adventurers of the guild, guild girl, cowgirl, Goblin slayer and his party, Sword maiden (with vision temporarily returned) hero's party, and possibly others (burglar and others are possible) are transported to another realm by the gods and proceed to show them that which has past and that which is to come that revolves around a certain Slayer. (they react to anime/manga/lightnovel stuff)
