—Menōmaru File:Featured.png File:Padlock-silver.svg.png Menōmaru (瑪瑙丸, "Agate") was a moth yōkai from the Asian continent who invaded Japan with his father Hyōga 200 years ago. They were opposed by the Inu no Taishō and, consequently, Menōmaru and Hyōga's power were both sealed to the ancient Tree of Ages. When the Shikon no Tama was shattered, one of the shards revived Menōmaru and he embarked on a quest to obtain his father's power. After discovering that one of the Great Dog Demon's swords, the Tenseiga, did not possess the destructive aura required to remove the seal on Hyōga, Menōmaru and his servants planned to steal the other sword, the Tessaiga, which did have the power.
