*About Koshika

Celebrating his 55th year in the comic business, Leiji Matsumoto sends a message of world peace through his latest masterpiece, "Silver Celestial: Out of Galaxy Koshika." Consisting of 8 full-color chapters, this work represents a culmination of the master's work.


In the year 2099, Earth is threatened by an evil from beyond the far reaches of space.
Standing between Earth and the impending disaster is the lovely Yoh Haguro and a young man named, Hajime Umino.
Once in an age long past, Earth was a double planet system with a "twin sister" -- a beautiful planet whose surface was covered with flowers. They are convinced they will find something there that could resolve Earth's dilemma. It is a journey to a world that exists in the year 11,365 million B.C., an era that touches on the farthest point on the Toki no Wa* where the past and future clash. There lies a reality suspended by time and gravity… A world of mystery that will unravel as the secrets of a silver cat-shaped pendant with strange powers and an enigmatic beauty by the name of Yoh Haguro are revealed. * The Ring of Time
