Alette 0: Red Moon of April is a science fiction visual novel for the PC and PlayStation Vita about Kohime, a Japanese girl who, after losing everything, set off on a one-month journey riding her Metal Knight.
Eighteen years have passed, but the shadow of the Great War is still upon the world. The war was between China and the United States of America. A series of sanctions imposed by the United States ignited this war, eventually including a total ban on trade between China-backed countries. A feature of the Great War was the use of war robots, pilot-operated biped machines, known as Metal Knights. Because of the use of them, the war lasted nine months. When China won the war, the world changed. Now the world is divided into nations which are composed of the United Europe, New Russian Republic, Japan Federation, Atlantic Community, and Great China. What brings the military balance between the nations are the Metal Knights. That is the reason each of the Big Five has Metal Knights. With the end of the war, the nations ceased the production and use of Metal Knights. This agreement is known as the Shanghai Pact. After the pact was sealed there was peace.
Everything changed when Great China broke the pact and attacked the frontiers of the Japan Federation, to regain all territories lost to Japan. The year is 2037, it’s been a month since Great China began its Japanese campaign, a war between Great China and the Japan Federation.
Your name is Kohime Togashi, daughter of Hideo Togashi and Akane Togashi. You were born in Japan before it became the Japan Federation. But you grew up on the border of the United Europe with Great China, formerly known as the Middle East. The battles between the United States and China happened there, eighteen years ago.
