He's not normal. He's a product of science; an engineered soul within an engineered body. He is not a creation of God; he is only a product of man's insatiable greed for power. And he is created for one purpose: to kill without mercy.
He was created to not feel the burning pain of wounds or the dull aches of bruises nor the heavy emotions of a human. He was made to withstand a nuclear explosion.
Yes, he is the perfect killing machine. The perfect assassin indeed.
That's what he's told.

Now, disguised as a student, he entered the school to carry his objective. He knew he'd complete the mission flawlessly but what he didn't expect were the new things that came with letting his subject come close to him.
