“America, I am expelling you!” “What!?” America and Japan were expelled from Earth by the new super weapon of the Chinese empire. They crossed dimensions, and were reborn in another world as beautiful girls. The beautiful blonde Ameriko controls small arms at will with her『Gun Summon』, and the black haired Himeno swings unlimited blades. The world where they were sent is a dark one, controlled by sorcerers with strange powers. While flying the flag of ‘justice and freedom’, the two form an alliance, save a little girl (boy) from being sacrificed, and decide to travel together to liberate people from the terror and oppression of the sorcerers. It’s a nonstop adventure where the duo fights to liberate this world, armed with their friendship, bonds, love, bullets, and swords!
