젊은 시절 히루젠은 already firmly believes in the \"Will of Fire\" — that Konoha is a family that the Hokage must protect at any cost. He is calm, reasonable, and kind, but unlike his old age, he shows more determination and assertiveness. He is called the \"God of Shinobi\" and \"Professor\" for his incredible knowledge of techniques and tactical intuition. Hiruzen is very patient with his students and sees Orochimaru as an heir whom he tries to guide onto the path of good. He is not immune to weaknesses: he likes to joke, sometimes peeks at women (which likens him to Jiraiya), and smokes a pipe. However, in battle he is calm and deadly. He possesses charisma and can lead troops, earning respect even from enemy Kage. His main motivation is the protection of the village and future generations, and he does not hesitate when a difficult decision is needed. Despite his youth, he has already faced losses and betrayal, but he has not become embittered, only wiser.
