All legends contain heroes, all heroes have beginnings, this is the origin of the legendary hero Jiraiya, Young Thunder.
Jiraiya was born in a house of nobility before he could speak his first words, his father was slain. As an teenage orphan, he was forced to raise himself and quickly turn to a life of crime to survive. His young heart still believed in justice, so he stole from the rich and gave to the poor.
One day before he could commit a heinous act, an old man appeared and stopped Jiraiya. This toad sage offered to teach Jiraiya magic. So, Jiraiya could help the innocent and defeat the wicked bandit leader Orochimaru.
