Description
Gyokuei is introduced as the devoted disciple of the monk Madenokoji Arikoto. His past is marked by profound tragedy; after losing his parents, he was left to starve on the streets until Arikoto found and saved him. This act of compassion fundamentally shaped his worldview, fostering a loyalty that transcends mere religious devotion. For Gyokuei, Arikoto is not simply a master but a savior he considers to be like a living incarnation of the Buddha, born into the world to rescue people like himself.

This deep-seated belief defines his entire personality and motivations. Gyokuei does not follow the Buddhist path out of a calling to the priesthood; rather, he became a monk solely to remain by Arikoto’s side. When Lady Kasuga of the Ōoku coerces Arikoto into giving up his vows to serve the female shogun, Iemitsu, Gyokuei is given the chance to return to Kyoto and a free life as a monk. He refuses without hesitation. He chooses to accompany Arikoto into the gilded cage of Edo Castle, believing his one true path in life is to follow and serve the man who saved him.

Within the oppressive and often hostile environment of the Ōoku, Gyokuei acts as Arikoto’s fierce protector and emotional anchor. Where Arikoto is gentle, restrained, and prone to accepting his fate with a quiet dignity that can border on passivity, Gyokuei is fiery, pragmatic, and ready to fight back against the brutal realities of palace life. He is described as having the spirit of a samurai rather than a monk, a distinction that becomes increasingly important as the story progresses. He is brave enough to speak frankly even to the shogun and remains perpetually suspicious of others when it comes to his master’s safety.

Gyokuei is forced to mature quickly in this unforgiving setting. When senior members of the Ōoku, jealous of Arikoto’s rising favor, are unable to hurt the master directly, they instead target and brutally assault Gyokuei, both physically and sexually. While Arikoto would counsel forbearance, Gyokuei processes his trauma into cold, calculated revenge. Demonstrating a cunning and ruthless intellect, he does not confront his attackers directly. Instead, he kills a beloved pet cat given to Arikoto by the shogun and frames the ringleader for the crime, resulting in the man being forced to commit seppuku. This act reveals a core aspect of his character: he is willing to become a schemer and a sneak, to abandon the moral purity of a monk, to protect Arikoto and avenge the wrongs done to them. He adapts to the brutal politics of the Ōoku with a speed that Arikoto cannot match, even becoming the most skilled swordsman in the inner chambers.

His relationship with the female shogun, Iemitsu, is complex and initially fraught with tension. He dislikes her, resenting the circumstances that have imprisoned his beloved master. However, he comes to understand that her feelings for Arikoto are genuine, and they share a common ground in their devotion to him. In a pivotal turn of the story, when Arikoto proves unable to father an heir, he is forced to make an agonizing request: that Gyokuei sleep with Iemitsu in his place. Despite his personal feelings, Gyokuei agrees, understanding the immense pain it must have cost Arikoto to ask. He then makes it his personal mission to succeed, not out of ambition, but simply to avoid letting his master down. In doing so, he fulfills a cryptic prophecy from his youth that he would one day father a ruler, as he goes on to have a daughter with Iemitsu who becomes the future shogun.

Throughout all the years of service, political maneuvering, and personal sacrifice, Gyokuei’s fundamental nature does not waver. He endures the decadence and corruption of the Ōoku not for the shogun or for power, but purely for Arikoto. After Iemitsu dies and Arikoto has fulfilled his final duties to her successor, Gyokuei is finally freed from his worldly obligations. In the end, true to the original path he chose only as a means to stay by his master’s side, Gyokuei returns to the life of a monk, taking the Buddhist name Keisho-in and leaving the world of politics and violence behind.
