Ch. 1Contract
After thirty-six days trapped in the Spacetime Tower, Utsusemi rescued the dying Itama Senju from a battlefield and formed a sharing contract with him. The contract healed Itama and granted Utsusemi new abilities, giving her the strength to enter the Warring States world.
- Utsusemi watched five shinobi attack the young Itama Senju and rushed to save him before he died.
- She carried Itama to the bronze mirror in the Spacetime Tower, which marked him with Ōtsutsuki crests and formed a contract between them.
- The contract caused time outside the tower to race forward ten years and gave Utsusemi access to Itama's memories and bloodline powers.
- Utsusemi used Yin-Yang Release to heal Itama's wounds, while their contract granted her Flower Release and the Sage Body.
- Utsusemi gained the ability to understand the Warring States languages and decided she was now strong enough to leave the tower.
