Confession manga features story by Nobuyuki Fukumoto and art by Kaiji Kawaguchi.

Two miles up in the unforgiving heights of Mt. Owari, hikers and friends Asai and Ishikura are hit by a blizzard and lose their way. Injured and sure of his imminent death, Ishikura confesses to killing a member of their university hiking club five years ago. However, Asai then stumbles upon shelter and carries them both to safety, only to realize that the confession has forever changed their relationship—and that the brutal elements may no longer be the most deadly threat around.
