The aftermath of a mysterious environmental catastrophe has left the land in complete desolation! While mankind has been able to rebuild the city, the catastrophe has caused some humans to undergo genetic mutations granting them special powers and abilities. These genetically enhanced humans are known as Alters. Kazuma has spent his entire life in the wastelands relying on his special powers to survive, but when a secret organization called ‘Holy’ threatens to take away his freedom, he will be left with a choice to join or die. His fight to seek the truth behind the ‘Holy’ will rage and consume humanity and Alter alike!

A Native Alter named Kazuma uses a plane to attack kidnappers and finish a job. Now the police organizations named Hold and Holy are after him, thinking he's a dangerous criminal just because he's a Native Alter. But, Kazuma proves that he's not bad when he takes on a renegade group leader, Biff, and saves the Native Alters. Kazuma just seems to have a grudge against Holy.

The organization of Holy is explained more clearly as is how Ryuho and Mimori first met. Both Ryuho and Mimori gain a bigger interest in the Native Alter, Kazuma.

After being captured by Holy, Kazuma is imprisoned and offered two choices; join HOLY or be imprisoned. When a sympathetic Mimori sets Kazuma free, he must find a way to escape the confines of HOLY Headquarters.

After hearing about Kazuma's escape from Holy, a new client, Ayase Terada, hires Kazuma and Kimishima to rescue her sick brother and the villagers from a Hold camp.

After returning from a mission, Kazuma and Kimishima find Kanami lying on the floor sick. Without the proper medical knowledge, Kazuma and Kimishima are forced to find a doctor of Holy.

With much resentment toward Hold and Holy, some Native Alters, including Kazuma and Kimishima, plan an attack on a Holy cargo van. Knowing this, Holy plats a trap.

Trapped underground, Kazuma and Tachibana call a temporary truce in order to find a way out. When they do a find a way out, a giant monster appears. Kazuma instantly resorts to attacking it, which Tachibana disapproves of.

After being told that he must re-enter Holy to rescue the others, Kazuma charges right though the front door. Unfortunately, a Holy member, Unkei uses his alter, the Mad Sprict, to control Kazuma and the events that surround him.

Wanting to stop Holy once and for all, Kazuma ventures into the Alter forest in hopes of gaining more power.

Kazuma and Kimishima come to a town of inners that love Holy due to a man named Emergy Maxfell. Not falling for his trap, Kazuma and Kimishima beat Emergy up and force him to show his true colors. Unfortunately, Emergy's alter only appears when he's in a pinch, and due to Kazuma beating him up, that's exactly what he's in.
