Sesshomaru's Sword

Lore & Background

Sesshomaru's narrative arc begins with him serving as a major antagonist, driven by a desire for power and strength while displaying disdain toward humans and half-demons. His journey shifts through a series of trials that lead to his redemption, transforming him into an anti-hero. A pivotal element of this transformation involves the human girl Rin, whom he saved from bandits after she tended to his injuries under a tree. In the original Inuyasha series, Sesshomaru and Rin share a close bond, but their relationship is not explicitly romantic, and Rin is not confirmed as the mother of any children. The twin half-demon daughters Towa and Setsuna, as well as the details about Jaken protecting them, the Dream Butterfly erasing Setsuna's memories, and their hiding in the forest of the Sacred Tree of Ages, originate from the sequel series Yashahime, not from the original Inuyasha canon.

In Their Own Story

In the sequel Yashahime: Princess Half-Demon, Sesshomaru's legacy is realized through his twin daughters, Towa and Setsuna, born from Rin. Transported to the modern era at age four by the Sacred Tree of Ages, Towa was raised by Sōta Higurashi before reuniting with her sister ten years later. Setuna, whose memories were erased by the Dream Butterfly, trains as a demon slayer under Kohaku. The sisters embody a fusion of their father's immense demonic strength and human resilience. Towa channels energy through her weapon and the Silver Rainbow Pearl embedded in her left eye, while Setsuna bears the Gold Rainbow Pearl in her right eye. Sesshomaru hides them in the forest of the Sacred Tree of Ages after Rin gives birth, ensuring his lineage continues to navigate unique paths as warriors.

Reader's Guide

Sesshomaru serves as a critical narrative bridge connecting the original Inuyasha storyline with its sequel Yashahime, spanning from the Warring States period to modern Tokyo. His daughters' existence links the original cast to new generations facing threats in both ancient and modern settings. Towa fights using a combination of sword techniques and inherited demonic powers, evolving her combat style as she learns to harness her abilities. Setsuna initially wields Kanemitsu no Tomoe before obtaining the fate-severing Yukari no Tachikiri. Their struggles with uncontrolled demonic blood and suppressed memories highlight the enduring influence of Sesshomaru's pure demon lineage on their development as warriors in a world incorporating traditional Japanese folklore.

• In the original Inuyasha series, Sesshomaru's relationship with the human girl Rin is not explicitly romantic, and she is not confirmed as the mother of his daughters.
• Jaken was once a lord among similar demons before becoming loyal to Sesshomaru, but he is not tasked with protecting Sesshomaru's daughters in the original series.

Origins and Lineage

Sesshomaru is the older, more powerful half-brother of Inuyasha, born of a great demon bloodline with a full-demon mother, contrasting with Inuyasha's mixed human-demon heritage. Chronologically over 200 years old, his appearance matches that of a 19-year-old human per Rumiko Takahashi's official profiles. He is usually accompanied by minions Jaken and A-Un. Initially an antagonist seeking power and despising humans, he eventually undergoes trials leading to redemption as an anti-hero. This evolution sets the stage for his role in Yashahime, where he is revealed to be the father of twin half-demon daughters.

The Legacy of His Daughters

Sesshomaru fathers two half-demon daughters, Towa and Setsuna, with Rin after she tends to his injuries. Jaken protects them in the forest of the Sacred Tree of Ages following their birth. Towa is transported to the modern era at age four, raised by Sōta Higurashi, and reunites with her twin ten years later. She wields the Silver Rainbow Pearl embedded in her left eye. Setsuna bears the Gold Rainbow Pearl in her right eye and trains as a demon slayer under Kohaku after memories erased by the Dream Butterfly begin to return.

Influence on Demon Slayer Dynamics

Setsuna fights primarily with a naginata, first using Kanemitsu no Tomoe before obtaining Yukari no Tachikiri. Her uncontrolled demonic blood triggers berserk states, and she struggles with suppressed sleep patterns due to the Dream Butterfly's influence. Towa combines sword techniques with inherited powers, channeling energy through her weapon. Their existence validates Sesshomaru's transition from antagonist to father, introducing a unique form of power that blends his pure demon lineage with human resilience.

Narrative Bridge Between Eras

Sesshomaru bridges the Warring States period and modern Tokyo in Yashahime. His daughters are separated by time travel via the Sacred Tree of Ages, with Towa raised in the Heisei period. This temporal displacement reflects the series' themes of time-travel and flashbacks. Setsuna regains normal sleep patterns after the Dream Butterfly's influence wanes, allowing her to develop new combat abilities and romantic feelings for Hisui.
