When the trio skip class to attend a local festival, an earthquake occurs and the man-made golems in the area become berserk and attack citizens.

After returning to university, Atsuma, Toya and Makoto find that things are in chaos, and that the mysterious "sealed ward" had been opened.

She captures Toya as ice falls on Makoto; as a result, Atsuma fights her by using his right arm that turns into something out of the ordinary that could harm a Devil Golem.

Escaping with local resident Karin and her bodyguard Raigar, Atsuma discovers that the two are part of a resistance movement that opposes King Caliban's plans to revive the Emperor of Fire, another Devil Golem hidden right under the city.

He reveals that he was very interested in Atsuma's right arm and started the golem riot to awaken its power, all for the Queen's revival and the restoration of Magic, the greatest technology in existence.

After the Lord of Earth's Magicore is drained of Ether, the group meets up with Sage, Raigar's teacher, who initially declines their offer to help them.

Raigar learns from the Sage that Atsuma's parents left him as a child at the base of her tower, so sick that she used the cells of an unknown Devil Golem named Infinity, to save him.

Atsuma, Karin, Raigar and Yuki defeat the Queen of Ice and save Toya; the mysterious man the group encounters several times reveals himself as Makoto soon afterwards.

However, Atsuma has a vision and the disembodied entity then reveals itself as Infinity, who was ordered to reconstruct all matter in the world to the time of the Era of Magic.

The protagonist of the game is Atsuma (アツマ), a student who is able to draw ether and enchantment power from others through his right arm to fight golems.
