AppearanceShihoudou has short blue (sometimes black) hair and brown eyes. She wears an oversized wicker hat, a blue-and-white striped cloak, mini shorts, and white bandages around her chest resembling a bandeau top. Most of her midriff is bared by her outfit, showing a flower tattoo on her left hip. She wields the Kusanagi no Tsurugi.
PersonalityShe appears to be a ditzy, vulgar, nonsensical person at first glance, but she is also surprisingly passionate and emotional. Evidence of her softer side appears in flashbacks; for instance, she allowed Muramasa to flee the Mibu with the demon child Kyo, knowing what would happen when the King found out (the resulting punishment injured her so severely that she was unable to move for three months). Shihoudou also remembers all of the failed experiments and shamans that have died for the Mibu Reconstruction Project and has created a graveyard for them in the labyrinth under Onmyoden. She made grave markers for them, buried the ones who still had bodies, and covered the area with mushroom-like cloud "flowers". She respects and secretly loves Sendai Aka no Ou. Because of her feelings for the king, she was unable to kill him when he started to walk an evil path. She has been hiding in the labyrinth ever since out of guilt and heartbreak.
StoryShihoudou is the eldest member of the Taishirou who appears in the manga. The Aka no Ou completely relied on her when she led the Taishirou, and he made her promise to kill him if he ever became corrupted. Unable to carry out that order because of her own feelings for the King, she retreated to the dungeon where the failures of the Mibu Reconstruction Plan are thrown. By the time Kyo and Sasuke encounter her, she has lived alone in the labyrinth for years. When Sasuke does not take her seriously and starts to attack, Kyo stops him and reveals that Shihoudou is one of only three people he admits he cannot handle in a fight. Shortly afterward, Shihoudou attacks Kyo and says he will have to prove his strength against her if he is going to have any chance against the current Taishirou or the King. Although Kyo does appear to defeat her with Byakko, he then drags her to her feet and demands to know why she threw the fight. Shihoudou says she's just getting old, but when Kyo provokes her about the Former Crimson King, she retaliates and hits him so hard that he smashes right through a stone wall, revealing the graveyard she has created for the Mibu Reconstruction Plan's experiments.
Later, she uses her own Red Eyes and manages to pierce her blade straight through the Sendai Aka no Ou's body, and in doing so discovers that he cannot be killed so simply. The Sendai Aka no Ou then proceeds to attack her in "thanks" for trying so hard to honor their promise. At the final death of the Sendai Aka no Ou, he falls to the the bottom-most pit of the tower. He lands in Shihoudou's graveyard for the Mibu's victims, and cries blood once last time before perishing in a shower of rubble and cloud-mushrooms. Shihoudou feels his death and hesitates for a moment. In the epilogue, Shihoudou is shown lying contentedly in a field of new cloud-mushrooms, near a newly erected grave bearing the hat of the Sendai Aka no Ou.
