Plot
Sōya Kuroi lives with a large cat-like creature called Sensei and a happy maid named Ginko. One day, strange floating beasts appear in the sky above Japan, and conventional weapons are useless against them, until seven men and women transform into powerful weapons and destroy them. Sōya finds himself pressed into battle, fighting not against the beasts, but against the seven heroes instead, as he becomes an unwitting pawn in an interstellar war that has come to Earth.

Characters

 * Sōya Kuroi (黒井 宗矢)
 * A high school-aged boy with amnesia who can barely remember what happened further than one year ago. He eventually regains some of his memories and realizes the members of Grand Paladin are using similar powers to the ones that led to the destruction of his home planet, Sirius, from which he is the only survivor. A running gag is that he is kept from eating meat, either intentionally by Ginko or accidentally by others.
