Shishinki

Shishinki was once one of Inuyasha and Sesshomaru's father opponents.He was a powerful Daiyōkai. His powerful Meido Zangetsuha was taken by their father and turned against the demon, ripping half of his head off. Shishinki hides the missing portion of his head behind a mask, masking the severe damage inflicted by the great dog demon. Wielding his staff, Shishinki is able to open numerous portals which suck their victims straight to hell itself. It appears that Shishinki's Meido Zangetsuha is too small to allow him to escape from hell as Sesshomaru was able to send himself into and out of hell with an incomplete but large Meido Zangetsuha.

Personality
Shishinki is a very cocky opponent who first encounters Sesshomaru when his eyeless assistant lures the demon into a trap. Shishinki takes great pleasure in teasing Sesshomaru about his inability to master the Meido Zangetsuha technique that Sesshomaru's father stole from him, and he recounts the story of how Tenseiga was created from Tessaiga, much to the disgust of Sesshomaru.

Shishinki's cockiness, leads him to underestimate Sesshomaru and Inuyasha, who work together to defeat the masked demon. Ultimately he is cast into hell by his own technique, used against him by Sesshomaru.

Name Meaning
Shishinki's name is written with the kanji for "death", "god" and "oni" which is a type of Japanese demon. "Death God" is a fitting name for someone who can send his opponents directly to hell.
