For years, life has been full of war and destruction, many lives have been lost and happiness has been taken away because of it. Gesteria is slowly starting to destroy all of humanity. However, there is still a chance for humanity to continue living with the existence of "cursed children" or "children who have powers beyond reason" different from other children, cursed children have bright red eyes, and that's where their power functions. Cursed children are an opportunity to stop the pain of humanity, it's just that some humans cannot accept cursed children because they think that the cursed child is dangerous.

some cursed children sometimes cannot control their strength and anger, making them go blind and kill humanity, since then, some humans do not believe in cursed children and think they should all be killed.

There are also some people who use cursed children as partners to fight Gesteria. By combining the two, the chances of winning will be greater.
