Ep. 22: Zero steals Setsuna's seal causing a demonic rampage that Towa and Kin'u must stop

Flashbacks reveal Zero witnessing the destruction of the Grim Comet at Sesshoumaru's mother's palace five centuries ago. In the present, Zero steals the seal from Miroku that contains Setsuna's demon blood, causing her to lose control and transform into a monstrous butterfly. Sesshoumaru and Toutousai sense her intensified demonic power, noting her inability to suppress the blood. Towa and Moroha fail to restrain her until Miroku's eldest twin daughter, Kin'u, arrives with Hisui. Following their instructions, Towa holds Setsuna down while Kin'u restores the seal, allowing Setsuna to recover. However, because the seal did not fully contain her blood, Setsuna vows revenge against Zero. Meanwhile, at Haneda Airport in the modern era, Towa's homeroom teacher observes the Grim Comet approaching again and encounters Souta and his young daughter Mei while they wait for Moe.
