The Hishimanji Guren Gang is a group of Tokyo street hoodlums who wear jackets adorned with a manji symbol on the back and sides and hakama adorned with flames on the sleeves. Led by Hachisuka and armed with a wooden cannon, the Hishimanji Guren pose a formidable threat in the community, acting as a sort of reserve army for criminals. After a pair of drunken ex-kenjutsu students picked a fight with some of the gang's members, Hachisuka led his remaining men in pursuit of the offenders, who ran and hid inside the Kamiya Dōjō. Unfortunately for the Hishimanji Guren gang, they are confronted by Himura Kenshin, who defeats their wooden cannon and quickly convinces them to disperse.
The Hishimanji Guren gang appears in Act 4 of the manga, but their exploits are removed from the anime, likely due to the manji's similarity to the swastika. In a filler episode, the Hishimanji Guren gang teams up with Raiko to try and put Megumi out of business.
- Kenshin splitting the cannonball fired towards him by the gang, occurs in both the manga act and the filler episode of the anime.
