Rin Yagami, a civilian orphan who traveled to Konoha 60 years ago, awakened the "Limited Tsukuyomi World" golden finger on his 10th birthday. This mysterious space that can be entered regularly has a time flow rate of 1:7, becoming his ultimate trump card to reverse his destiny and achieve steady cultivation.
With the deduction and hard training in the Tsukuyomi world, he emerged as a commoner. In the Third Ninja World War, he warned in advance on the Kannabi Bridge battlefield and saved Obito Uchiha's life. His reputation as a master tactician resounded throughout the ninja world. After the war, he joined the ANBU and went into hibernation. As he spent time with Kurenai Yuhi, the two gradually fell in love and became partners.
He used the Tsukuyomi world to deduce future crises such as the Nine-Tails Rebellion and Payne's Invasion, and made plans in advance. He and Kurenai worked together to protect the civilians of Konoha, resist the Kyuubi, and establish an early warning mechanism. During the Shippuden period, he became the key strategist of the Ninja Alliance, assisting in sealing Kaguya with illusions and tactics.
In the end, the war ended, he refused the high position, returned to a peaceful life with Kurenai, compiled the essence of the "civilian tactics" of guarding Konoha throughout his life into a book, and passed it on to future generations, completing a perfect life from an unknown orphan to a guardian legend.
