Rin Nohara

Childhood and the Academy: Rin was Obito's friend from an early age, supporting him and helping him enter the Academy. She was one of the first to truly believe in him.
Team Minato: Along with Kakashi and Obito, they participated in missions during the Third Shinobi World War under the leadership of Minato Namikaze.
Kidnapping and interrogation: Shinobi from Iwagakure kidnapped Rin to extract information about Konoha. Kakkō placed her under genjutsu, but Rin remained firm and didn't reveal anything.
Rescue: Kakashi and Obito came for her. During the battle, Obito awakened his Sharingan, but was crushed under rocks after an enemy collapsed. Obito's request: Before he was completely buried, Obito asked Rin to give his remaining Sharingan to Kakashi—as a sign of recognition of his strength and as a gift for achieving the rank of jonin.
Operation on the move: Rin wasted no time performing Kakashi's eye transplant right there in the field. Afterward, she and Kakashi were forced to retreat as enemy reinforcements arrived and the collapse continued.
Mission to the Kannabi Bridge: Minato's team was tasked with destroying the bridge to slow the enemy's advance. It was during this mission that the kidnapping, rescue, and collapse occurred.

Medical Ninjutsu: Rin was a talented medical ninja, treating her comrades' wounds right on the battlefield.
Sharingan Transplantation: In an extreme situation, she was able to transplant Obito's left Sharingan into Kakashi's eye socket without any special tools, demonstrating her high level of skill.
Elements: mastered the elements of Water, Fire and Yin.
Taijutsu: Demonstrated hand-to-hand combat skills (for example, during the genin exam).
Willpower: did not break under genjutsu during interrogation, did not give information to enemies.

Peacemaker: Often smoothed over conflicts between Kakashi and Obito, while remaining objective.
Caring: she always treated her comrades, supported Obito morally, and believed in his dream of becoming Hokage.
Devoted: the life of the village and the safety of her loved ones were above all else for her.
Strong-willed: even under a strong genjutsu, she did not reveal Konoha's military secrets.
Intelligent: mastered complex medical techniques early and was noted for her insight in stressful situations.
Feelings: She was in love with Kakashi, but she truly cared about Obito and tried not to hurt his feelings, even though he was in love with her. Her favorite word was "friendship," her favorite food was strawberries, she didn't like tsukudani (small fish and shellfish simmered in soy sauce with sugar), and her hobby was collecting shells.

Hair: Brown, cut in a bob to chin length. As a child, my hair was longer, almost to my shoulders.
Eyes: brown.
Distinguishing features: Purple rectangular markings on both sides of the cheeks.
Cloth:
At the Academy: a light shirt with a purple ribbon on the chest, a burgundy vest.
As a genin/chuunin: a tight-fitting black V-neck shirt, a light purple apron skirt with a belt and slits on the sides, black shorts, maroon thigh-high socks, shinobi sandals, and a Konoha forehead protector. She also carried a small first aid kit and a backpack with equipment.
Accessories: small red bracelet on the left wrist.
