In case you haven't seen the ridiculously popular anime or read the Wikipedia page, The Melancholy of Haruhi Suzumiya
is about an impulsive high school girl who also
happens to unwittingly possess the ability to control reality. Her friends in the "SOS Brigade" after-school club, who all have supernatural or extraterrestrial connections except for irritated Everyman Kyon, attempt to keep her from getting bored (and thus remaking the universe) while also hiding the true existence of aliens, psychics, and time travelers from Haruhi.
to explain all that for the concept of the new DS Haruhi
game from Sega to make any sense. It's a board game in which the SOS Brigade rushes to solve unexplainable incidents and destroy evidence of otherworldly activity before Haruhi shows up. At least, that's as much as we can figure out. Not that it matters -- sales of this game will occur based entirely on the strength of whatever preorder bonus Sega and Haruhi
publisher Kodansha decide to throw in.
