Gyakushu! Volume 1 (Gyakushu!)

A nameless man, bandaged from head to toe, stands alone in a field of fresh corpses and carnage. Blood drips from his sword, dying the virgin snow red. The battle may be over for now, but his one-man war has just begun! Mystery and intrigue surround this warrior, as clues about his past lead to a chilling confrontation in his future. The truly inventive setting may or may not be earth--may or may not be the future or the past--the only certain thing in this world of ice and death is white-hot revenge!
