Killer 7 Europe

In an alternate version of the Earth's history, a treaty was signed in the early 21st century, during which all countries willingly destroyed their nuclear arsenals, ending international conflicts. The presumed era of world peace, however, is marred by continuous attacks carried out by a new terrorist group called 'Heaven Smile', which consists of human mutants under the influence of a lethal virus, and targets the United Nations and the International Ethics Committee (IEC). Meanwhile, the relationship between the United States and Japan deteriorate, as the latter becomes controlled by a party that proposes to sever connections to the USA.
