Japanese novelist Kyogoku Natsuhiko is a fan and disciple of Shigeru Mizuki,the author of the manga "Gegege no Kitaro".He wrote the script for Gegege no Kitaro anime s04 ep101,and provided design and voice acting for the character Ikkokudo,an onmyoji who exorcises yokai through Kotodama(word spirit).His appearance,demeanor,and unhappy expression are clearly similar to Chuzeji Akihiko aka Kyogokudo from Kyogoku's novels,but he is able to destroy real yokai.He can influence yokais' cognitive for themselves through language and restore them to "natural" objects by that.Kyogoku actually taught the audience a simple lesson on yokai culture through this character.
Also,a series-fixed line in the trailer for this episode was replaced with Kyogokudo's catchphrase "There is nothing incredible in this world."
