Ch. 1Unlimited Blade Works, Hokage Version
Shunren, an orphaned Uchiha who could not learn Ninjutsu, sought another way to gain strength before the coming Third Shinobi World War. He discovered he could shape Yin Release into weapons, but his attempt to create a powerful sword quickly failed.
- Shunren failed at the Transformation Technique after three years of training and decided to pursue alternatives to Ninjutsu.
- Shunren reviewed the Uchiha scroll on Yin Release and worried that the Third Shinobi World War would begin in less than a year.
- Shunren shaped spiritual energy into a kunai and found that it cracked after repeated strikes against a real one.
- Shunren tried to form a black-and-white sword inspired by his former world, but it shattered after one second.
