Jiraibuster (ジライバスター Jiraibasutā?): Jiraiya's raygun introduced in Episode 13, it appears to be a weapon handed down to the Yamaji family. It uses three different types of ammunition: a medical cartridge that shoots anesthetic rounds, a signal cartridge that shoots signal rounds, and a material destroying cartridge that can destroy rocks. The Jiraibuster is mainly used as a defensive weapon, since it is not capable of firing lethal shots.
