One day, Bacha is attacked by a mysterious beast. When she reaches for the gun, it becomes physical. She shoots and the beast dies. But Bacha is seriously injured and dies too.

When Bacha opens her eyes, she sees several different people.

"Welcome ability users. We are here to collect the stars that created your ability. To obtain them we need you to undergo extreme situations, and activate your abilities. Some of you already know how to use your ability. We haven't taken them yet. However, if you do not cooperate with use, we will take them away."

Bacha understands that the gun to her head is an ability.

"Is everyone here? Strange, there should be twenty of you but there's only sixteen. That means there are four people that have a double ability."

Bacha is in awe. She is one of the four as she has her other ability turning sticks into knives.
