They were first shown stealing food from the citizens of Okobore Town before they were confronted by Jack. Shutenmaru clashed with Jack until Kaido arrived in Kuri, prompting the thieves to retreat.
A few days later, one of Holdem's subordinates set Mt. Atama on fire, forcing the thieves to flee. Shutenmaru decided to go to Bakura Town to retaliate against Holdem. After arriving there, Shutenmaru witnessed Yasuie's execution along with Kin'emon and Inuarashi. Afterward, Shutenmaru learned that Kin'emon framed him for theft and got angry. Kin'emon apologized and asked for his help.
Shutenmaru later took Kin'emon and Inuarashi to the graves of those who tried to fight Kaido ten years ago. When Shutenmaru decided to join the Kozuki Family's alliance, his gang joined as well.
Translation and Dub Issues
The group is frequently called the "Atamayama Thieves", which is used by the official Viz translation. Atama-yama is the untranslated name of Mt. Atama, with yama meaning "mountain".
