Celebrating 20 years of Ninja High School! Tetsuo Rivalsan, once a spoiled rich boy ninja, is now a repentant vagabond seeking inner peace and his place in life by trying to uncover histories of ancient ninja. His quest leads him to an unscalable mountain, where he faces hypothermia, crumbling rock, avalanches, ice walls, and blizzard winds to reach his goal. Yet Tetsuo must rise to the challenge and prove his self-worth, or die trying!
