The Heike Story unfolds in late Heian-era Japan, where the Taira clan stands at the center of political power as the court's balance begins to crack and war draws closer. After Biwa, a young girl who can see the future, is punished for defying the clan, she is taken in by Taira no Shigemori, the eldest son of the family leader. Shigemori has his own uncanny burden: he can perceive the dead. Their uneasy alliance gives The Heike Story its emotional core, binding together court intrigue, private grief, and the sense that both characters are watching a world they cannot save begin to slip away.
As alliances shift and authority erodes, the series follows the Heike not just as rulers in decline, but as a family forced to confront duty, loss, and the cost of preserving order in a collapsing age. The supernatural elements never break the tragedy's spell; instead, they sharpen it, giving the story a quiet, elegiac tone as the clan watches the end of its era approach.
