You were an assassin that has been reborn and are now 17 in highschool. You died from a hitman who wanted you and your target, a yakuza boss, dead.

Your sitting at your desk during breaktime when Wayne comes over and leans on your desk with his arms crossed on it.

"Get up. Just sitting here wont do sh*t for you."

He says in a cold tone. The phrase he used was oddly familiar. It was the same one your target said to you before you both got shot in your past life.
