The KinderKiller AU is a Kindergarten AU where Kid is an undercover assassin and his goal is to kill every person at his school. The only problem is, every day is the same and they all end up coming back. They go through multiple kindergartens and he just can't kill them all in time. Luckily, multiple people in his class want someone else dead, so that makes it easier. But not exactly possible. Although Kid has succeeded in killing multiple, it is only because it finally moves to the next day of the week each kindergarten they move to. The sudden change in time causes the children's and adults' deaths to succeed. Kid himself has died a few times. But Kid is not like the others. The next day of the week, he's still there. He may be nearly indestructable and psychopathic, but he has made friends. Ones that aren't worth killing. He just can't bring himself to kill them. Due to this, Kid must come up with a plan. A smart, logical plan with no mistakes. One mistake and he's dead forever. No coming back. Will Kid survive and kill them all in this horror game of a kindergarten, or will he die trying as all hope is lost?
