Description
Shu no Bon is a yōkai from Japanese folklore, characterized by bright red skin, a large mouth stretching ear-to-ear filled with sharp teeth, and distinctive needle-like hair. A horn protrudes from his forehead, and he typically wears traditional Japanese clothing. His appearance draws from Aizu region folklore, where encountering him was thought to cause extreme fright or death. Shigeru Mizuki's work popularized the spelling "Shu no Bon," though variations like "Shu no Ban" exist. Folklore depicts him as a master of psychological terror, startling victims by revealing his true form.

Across *GeGeGe no Kitarō* adaptations, Shu no Bon consistently serves as a minion to Nurarihyon, addressing him with "-sama" and demonstrating high loyalty. His competence and threat level vary significantly:
- In the 1985 anime, he develops substantially when ordered to kidnap Yumeko. Confiding his insecurities and touched by her kindness, he betrays Nurarihyon to help her escape, later calling her an "angel." Despite this, he later assists Kitarō in curing a transformation curse on Nurarihyon, ultimately returning to antagonistic roles. His final arc concludes with a sacrifice, attacking Nurarihyon before both fall into Jigoku's lava.
- The 1996 anime portrays him with increased assertiveness, occasionally questioning or talking back to Nurarihyon.
- The 2007 anime emphasizes comic relief; he faces repeated dismissal threats for incompetence, like failing to capture Yanari spirits. After inadvertently aiding Kitarō by revealing Nurarihyon's plans, he is briefly fired but reinstated when his actions accidentally enable Yōkai Castle's revival.
- The 2018 adaptation elevates his combat prowess, depicting him as physically formidable. He demonstrates strength comparable to Neko-Musume, durability against Kitarō's attacks, hand-to-hand proficiency, and agility. He also uses modern weaponry, like a machine gun against human militias, yet retains his primary comic relief role.

His abilities include transformation into human form to shock victims, summoning other yōkai by tugging his lower lip, and powerful headbutts featured in manga and the 2007 anime. Enhanced physical attributes like strength, durability, and agility are most prominent in the 2018 series.

Folklore associates Shu no Bon with terrifying lone encounters on dark roads. Some legends describe collaborations with yōkai like Shitanaga-Babaa to capture humans. Media outside the main series, such as the play *Tenshu Monogatari*, depict him serving figures like Kame-hime of Inawashiro Castle. His brief appearance in the first live-action film occurs during a crowd scene at The Great Yōkai Trial.

Manga appearances include *Kitarō Kunitori Monogatari*, where he competes in a sumo tournament, using acrobatics against Kitarō before losing, highlighting his agility and combat focus in source material. His personality fluctuates between menacing and inept across media, heavily influenced by his loyalty dynamics with Nurarihyon and, in the 1985 series, moral conflict spurred by Yumeko.
