Nobori in Naruto

There is much uncertainty about Nobori's past as we still don't know anything about his clan, and his history. In the manga or its anime adaptation, he only made a few brief appearances.

He first debuted in Live or Die: Risk it All to Win it All!, episode 56 in the Chunin Exams Arc in the series. In the arc, he was introduced as a classmate of Konohamaru Sarutobi, the Third Hokage's grandchild, and a ninja academy student. When Hiruzen Sarutobi, the Third Hokage, asked who they would protect, Nobori agreed with Daichi and said he would protect his friends.

In the Academy Lead Mission, during a survival exercise, Nobori was a member of a temporary team, alongside his fellow academy students Matsuri and Daichi, under the leadership of Hinata Hyuga.

In the Konoha Plans Recapture Mission, Nobori and other academy students were thrown out of their classes under the threat of a live bomb located somewhere in the academy. Nobori, Daichi, Koji, and some other kids went to an area to throw kunai knives at a wooden block.

Soon after they started throwing their kunai, Naruto Uzumaki, Rock Lee, and Choji Akimichi came to the scene to stop them under the suspicion that the bomb was planted in the wooden block, which turned out to be true. Nobori hasn't shown up since these appearances, and his absence makes it impossible to ascertain whether he's dead or alive.

Nobori is currently assumed to be alive and well unless any information surfaces indicating otherwise.

Nobori never had the chance to interact much in the series and did not have any significant role in the series. He never had an opportunity to showcase his personality. However, based on his brief interaction, it can be deduced that Nobori deeply cares for the well-being of his friends and wants to protect them.

Nobori is a young boy with small black eyes and short, light brown spiky hair, and thin eyebrows. He wears an orange t-shirt underneath a brownish jacket which is held together with laces at the front, paired with a pair of blue pants and sandals. He also wears a black belt with a silver belt buckle.

Nobori is a former Hidden Leaf Ninja Academy student. However, he only made a very brief appearance in the series and was never shown employing any jutsu or skills. His arsenal of skills is unknown due to a lack of evidence.
