Modern Japan. By day, the capital of this small, proud country is just another bustling metropolis, many of which exist across the globe. But when the sun sets and the silvery Moon rises over nocturnal Tokyo, strange and sometimes terrifying things begin to happen in the city. This is not about juvenile delinquents, adult gangsters, or even the legendary yakuza; monsters and magic are actively involved in these events. Rumor has it that mysterious figures are searching for a mystical Silver Crystal upon which the fate of the world depends...
A small black shadow glided silently through the streets of Tokyo. Occasionally the shadow would freeze, revealing pointed ears, a long tail, and a glimmer on its forehead. The fearless little creature was actively searching for something in the city. Only the legendary warriors of the distant past, who perished in an ancient terrible battle and were reborn only recently, could save Earth. The cat must discover them before the enemies gather enough strength to awaken a great evil...Residents of Tokyo
