Dokugakuji

This loyal youkai serves as the bodyguard to Prince Kougaiji, the son of the Ox-Demon Gyumaoh, whom the Sanzou Ikkou seek to stop reviving. He is the older half-brother of Sha Gojyo and was previously known as Sha Jien, a figure deeply connected to Sha Gojyo's tragic past. Dokugakuji became Kougaiji's protector after joining him, driven by a profound commitment. He wields a summoned sword in battle, often engaging with Gojyo when their groups clash.
