My name is Qianshou Jin, and I'm an utterly ordinary test subject.
All I've ever wanted is to stay alive and, while I'm at it, get a decent meal.
But they keep forcing me to become the Demon King.
Danzo thought I was a fish on the chopping board.
So I had no choice but to sacrifice the Sharingan arm he was so proud of.
In return, the System rewarded me with [Perfect Wood Release: Sage Art: Wood Release: True Several Thousand Hands].
Hiruzen Sarutobi: "Has the First Hokage manifested? No, this evil aura..."
Orochimaru thought I was the perfect material for achieving immortality.
So I had no choice but to sacrifice his army of Impure World Reincarnation shinobi.
In return, the System rewarded me with [Soul Laws: Divine Authority].
Orochimaru (kneeling fervently): "You are the ultimate culmination of science and truth! Please, let me follow you!"
Obito Uchiha thought I was a mere ant in his plans.
So I had no choice but to snatch his Nine-Tails and Demonic Statue of the Outer Path and sacrifice them.
In return, the System rewarded me with [Creation Rinnegan: Kamui Version].
Obito (his faith crumbling): "Why... Why do you understand the Infinite Tsukuyomi better than I do?!"
I'm really just an honest guy who wants to stay alive! (shrugs)
Why do they call me "the end of the Shinobi World" and "a walking apocalypse"?
Honestly, they have no manners at all.
