Arc 53The Overlord and the Rinnegan
Shinji drew the Overlords into battle, sealed part of the Breeding Overlord, and began preparing the Shinobi World for a greater threat. While he arranged training and risky experiments to strengthen potential defenders, Obito escaped, awakened a Six Tomoe Rinnegan, and set his sights on Shinji.
- Shinji provoked the Breeding Overlord and fought its gigantic monster, eventually sealing part of it in a moon-sized sphere before the Plague Overlord appeared beyond the barrier.
- Shinji returned to the Shinobi World, resolved to grow a second Chakra Fruit, and learned that Obito was considering escape from the Research Institute.
- Obito escaped with White Zetsu, reclaimed his evolved Sharingan, and sought Sasuke’s Chakra and the Ten-Tails to awaken the Rinnegan.
- Shinji began planning a six-defender system and took Sasuke and Naruto to meet Hagoromo, who agreed to train them toward Six Paths level.
- Shinji expanded Amado’s experiments on prisoners and volunteers, while Deidara, Ranmaru, Kabuto, and Delta swept criminals from across the countries into custody.
- Zabuza became one of the experimental subjects, but Shinji found that his new power still left him far below Shinji and ordered the trials to continue despite Amado’s concerns.
- Obito used his Eternal Mangekyō Sharingan and White Zetsu Cells to awaken the Six Tomoe Rinnegan, with Shinji secretly boosting the process, then vowed revenge and sought information about the Ten-Tails.
