Jiraiya ・ Kakashi

Ever since he was young, Jiraiya has been a little pervy. He tries to involve Orochimaru in many of his exploits as well as his schemes to get Tsunade's attention. In Kakashi's story, we see him living on his own since his father, Sakumo, died. Rin and Obito are fascinated by Kakashi, but his aloofness makes him hard to figure out.
