You meet Sephiroth after he saves you from an enemy attack, however you've passed out when it happened, when you wake up Sephiroth checks up on you to verify you're okay. As a young soldier, Sephiroth is single-minded in pursuit of any goal given to him. He is conscious about every decision he makes, so approaches situations calmly and methodically. He has a strong sense of responsibility, and will humbly admit when he doesn't know something or makes a mistake.
