As the God's will

A high school student Shun Takahata spends much of his time playing violent video games.

One morning at school, he whines that his life is completely boring but then he suddenly finds himself forced to participate in a game of DARUMA.When the DARUMA DOLL  turns toward the blackboard, it exposes a button on its back that the students can attempt to press to end the game, but if the doll spins back around and sees anyone moving then those students heads will explode.

After DARUMA game where Shun was the only one who survived, Shun finds his childhood friend Ichika Akimoto and make there way to the GYM. There they play a MANEKI NEKO, where students dressed as mice attempt to throw a ball into a hoop attached to the collar of a giant cat doll, while trying not to be eaten or crushed. The game was won with the aid of Takeru Amaya. The three of them are then put out of consciousness by the sleeping gas released by the giant cat doll.

They wake up to find themselves with other students in a room inside a giant cube hovering Tokyo, facing the next test: students all over Japan and elsewhere in the world face similar tests, and the handful of survivor are being brought inside other cubes.

The next game is KOKESHI, where the students have to be blindfolded and guess which of four floating Kokeshi wooden dolls is behind them within 10 seconds after the end of a short song. If they fail to do so, they will be hit with a red laser and the dolls will use telekenesis to destroy their bodies. If the Kokeshi lose, they will explode and one of them releases an answer key which opens the doors and frees the students to the next level. Shun meets and saves Shoko Takase by winning the game

after winning the game Shun reunite with Ichika and Yukio Sanada, whom they save from being killed by a fifth Kokeshi by holding their hands.

The four join Eiji Oku and Kotaro Maeda to the next level, where they have to use their keys to unlock a giant smiling head. Amaya brings in three more keys and kills a prisoner that he brought into the room. The seven survivors use their keys, and the giant head rolls away to dig a tunnel into the next room. Meanwhile, each player is displayed on television screens for the others to see. The next game is Shirokuma, a white polar bear that appears to them inside a frozen room. The students have to all answer the white bear's questions honestly, otherwise they will be forced to single out the one that they suspect to be lying to be killed. Shoko and Yukio get killed, and Shun soon realizes that the bear is the true liar and that it's real color is black, therefore winning the game and surviving with the other four students.

The final game, presented by a MATRYOSHKA DOLL is a game of kick the can that must be completed before sundown. The remaining five each pick a stick, and who gets the red one plays the "Devil". Whoever gets the face shown or seen by the Devil, is caught and thrown into a cell. Kicking the can in the middle will make it explode, killing nearby players. Takeru got the red stick and soon two students are caught while Shun finds an armor to conceal his face. Shun falls into the sea while chaining Takeru to the armor: as Takeru fights to pull the armor up to avoid being pulled down, Shun climbs back up, having freed himself from the armor. Both race towards the can, and Shun succeeds in kicking the can first, thereby winning the game. The Matryoshka doll reveals that in fact the explosion is a lie and that none of them will be killed by losing the game. They have an popsicle party, where they learn their fates on the wooden stick, and that the intention of the last game were simply for entertainment. Shun and Takeru live while Ichika, Eiji, and Kotaro are killed by a Matryoshka doll with lasers that disintegrated them.

In the end SHUN and TAKERU became the "God's children".
