Rin Nohara

Rin had chestnut-colored hair cut in a chin-length bob, brown eyes, and distinctive purple rectangular markings on her cheeks. She wore the standard Konoha shinobi outfit: a forehead protector, comfortable combat attire, and a backpack containing medical equipment.

Relationships with Obito and Kakashi
She treated Obito with warmth and support. She believed in him even when others doubted him, and she helped him believe in himself. Obito was in love with her, and she valued him highly as a friend and comrade.
Her feelings for Kakashi were more complex: she admired his abilities, but she saw how he closed himself off from the team. At the same time, she tried not to pressure him, but to gently nudge him to be more human.

Iryōninjutsu (medical techniques). Rin, already a chunin, had mastered advanced medical techniques and could provide medical assistance directly on the battlefield.
Practical. She didn't seek to be at the center of the fray, but she was useful: stabilizing the wounded, helping plan actions, and supporting the team.

A peacemaker and the team's pillar of strength, Rin often smoothed over the tensions between Kakashi (who was cold and mission-focused) and Obito (who was emotional and impulsive). She had a way of speaking so that both felt heard.
Kind and caring, she genuinely cared for her comrades and tried to help them not only with her actions but also with her words.
Strong-willed. When she was kidnapped by Iwagakure shinobi and interrogated under genjutsu, she didn't break or reveal any secrets—a testament to her strong will.
Responsible. As a medical officer, she took her duties seriously and never lost her nerve even in difficult situations.

Before the avalanche when Obito was hit by a rock (in Kakashi Gaiden), Rin Nohara was a chunin and medical ninja on Minato's team, along with Kakashi and Obito.
