The Japanese have a proverb which states that "Hair is the heart of a woman". Under the cover of twilight a young man climbs up to meet his lover using her hair as a rope, but when her father forbids that they see each other again, what would happen if their "heart" were severed?
In feudal Japan, the townsfolk are under attack by fantastical creatures that appear out of nowhere, summoned by henchmen of the evil Kokusengen. Coming to their aid is an ancient clan of calligraphers whose drawings come to life, whether in the form of a giant sword, a wall to protect them, or monsters to do their bidding. Shiro, Shimaki and Ena must draw and battle their way to victory before their adversaries' creations put them in the grave.
