This story about Shu Ouma who accidently acquired an ability that was called the power of kings. It is basically a power that can pull out tools or weapons from human that was called voids. Some of the power was healing, sword, shield and etc. When he pulls out the voids, the person will be unconscious and if the voids were destroyed, the human also will died because it is basically the human soul that taken in the form of tool or weapon. Shu was just unfortunate boy that caught in the fight between government with rebel that known as undertaker. He try to save a girl and while doing so, the girl choose Shu to obtain the power of kings. He reluctanly joined with the undertaker and fight with the government.
The anime story is quite good but the second arc for me is not that entertaining. Shu got a sister before but his sister die due to virus that known as apocalypse virus which is turn human to crystal. It happened when Shu was a kid and many people died during that time. It is known as lost chrismas and Shu lost his memory about that incident and his sister. The first arc is enjoyable and Shu start from being a wuss and coward changes during his fight with the government to a fine hero.
But unfortunately, after the first arc the story take a turn with a town was close down by the government together with Shu and his school friends. His friends at school already know that Shu have power of kings and choose him as a leader. Shu try to become good leader but everything change to bad when one of Shu friend sacrifice her life for Shu and died. Shu was shocked, sad, and traumatized that turned Shu to a cruel leader.
That is why I kinda hate second arc. Basically the hero, Shu become a jerk. Almost all his friend before when he fight together with them were trying to throw off Shu from his leader position. It really pissed me off when one of his friend sold her body to obtain something from some unknown jerk. The ending is also kinda sad because Shu lost his girl, Inori and also one of his hand. But don't get me wrong, it is still a really good anime that is worth to watch.
At the final, Shu finally grow back to become a dependable leader with his final fight with his best friend and his sister. Its happened that his dead sister is respawn from his girlfriend Inori. It is really have dark story but who knows, you guys may like it.
