What is orochimaru's life background?

Orochimaru's parents died when he was a child. After graduating from Ninja School at the age of six, he joined Jiraiya and Gang Shou as a member of Sarutobi Hiruzen's class.

He was rated as a "genius boy by Huo Ying's third generation, and it took decades to appear a genius", so he was highly valued by his master, which also made Jiraiya jealous of him and thought that "orochimaru is the only one in the teacher's heart". Therefore, when he was young, his relationship with Jiraiya was always in a state of mutual support and competition.

Seeing his parents and companions die one by one, orochimaru, who is kind in nature, felt the fragility and shortness of life, and orochimaru himself loved research, so he began to study the young Immortal Technique and the art of coming back to life.
