Episode 25 (Hanyō no Yashahime)

Wielding the Tenseiga is the twenty-fifth episode of Hanyō no Yashahime, and the premiere of the second season titled "The Second Act." It aired online at the second of October, one year after the spinoff anime had premiered in Japan.

Synopsis

 * 1) Towa uses the Tenseiga to revive Setsuna.
 * 2) Tōtōsai arrives and reforges Setsuna's broken naginata, constructing the powerful Yukari no Tachikiri.
 * 3) Tōtōsai tells the half demon princesses to seek out Bokusenō, who may help them locate a demonic weapon for Towa to use.

Plot
With Tenseiga having been broken by a spiteful Zero, Towa begins to infuse the heavenly healing sword with her limited amounts of demonic energy in order to revive Setsuna. Tōtōsai and Jaken arrive at the scene, and Tōtōsai states that he needs three whole days to mend Tenseiga. Unfortunately, by that time, Setsuna's vital essence will have been already sent to the Underworld, thus rendering the repaired Tenseiga powerless and that they have no other option but to rely on Towa's own demonic strength and will. While the still-hesitating Towa struggles to utilize Tenseiga's heavenly abilities to try and save her twin's spiritual essence, Tōtōsai retrieves the hilt of Setsuna's broken naginata and begins to restore it to create the Blood Blade she inherited from being one of Sesshōmaru's half-demon daughters- the Yukari no Takichri! This greater infusion of a blend of pure demonic/mystical energy attracts a mass of demons both living and deceased. Moroha utilizes her somewhat stronger and more effective spiritual powers (a feat that is directly due to Moroha no longer keeping the red Rainbow Pearl inside her shell rouge) to eradicate/purify a few dozen demons' all at once with one single arrow alone, with backup from Kirara, but the two are largely outnumbered by their fellows.

As the horde of demons' turn their attention to a concerned Sesshōmaru and his unconscious twin daughters, the recently resurrected Setsuna awakes upon her name being said by her father, who fiercely holds her greatly advanced and upgraded naginata aloft, the Yukari no Tachikiri, and easily slays the demons with incredibly a short amount of seconds, which Moroha and Kirara had not been able to do away with, in one single stroke. Sesshōmaru then hands the broken Tenseiga to Tōtōsai for its three-day mending, and leaves with Jaken.

Before departing himself on his demon-bull companion Mō-Mō, Tōtōsai warns Setsuna to never let herself be murdered again as the Tenseiga can only return sentient beings, human or demon, to life only once. While Towa still remains unconscious from having drained herself of all her demonic energy to resurrect her twin sister, Tōtōsai instructs Setsuna on how look for a mystical Kyuyokon root from the two thousand and fourteen year-old demon-tree Bokusenō to receive a proper demonic weapon for Towa, in place of the Knockoff Kikujūmonji that she has been foolishly wielding since her return to the timeline of her birth.

Trivia

 * Clips from previous episodes were showcased at the beginning.
 * This is the first episode to have Reborn as the opening theme, and Transparent World as the ending theme.
 * Towa wields the Tenseiga for the first time. The way her innate dog-demon powers temporarily disappear had happened to Inuyasha when he was at Mount Hakurei due to its strong spiritual shield purging anything or anyone demonic.
 * No longer having the red Rainbow Pearl to limit their true strength and effectiveness against evil, Moroha's inherent spiritual powers are now free to further develop properly as well as increase in strength and effectiveness. (For instance, for a time, her sacred arrows could only display a very small amount of spiritual energy that could only wipe out and/or purify one target at a time. From this episode onward, it takes only one of Moroha's sacred arrows for a dozen or several more targets to be fully purified or eradicated all at once).
