Volume 1

 * A decade prior to the beginning of the story, Vent and Aile lose their mother to a Maverick raid on an amusement park and becomes orphaned. They are taken in by Girouette, the owner of Giro Express, a delivery service.
 * Giro is contacted by an unknown person to deliver a package containing Biometal Model X to a rendezvous point in a forest.
 * Vent, Aile, and Giro are ambushed by Mavericks after meeting up. The siblings escape the area while Giro covers their retreat. Here, they meet with Prairie, the leader of the Guardians, but their meeting is cut short when a Maverick attacks the group.
 * Model X lends its strength to Vent and Aile, allowing them to "Megamerge" and transform into Mega Man Model X. With the help of Model X, the Maverick is destroyed. After finding Giro, in the form of Mega Man Model Z, they board an airship deemed the Guardian's headquarters.
 * Later, a Maverick attack is spotted at the Slither Inc. main office. The trio meet the president of Slither Inc., Serpent, and his Reploid guardians, Prometheus and Pandora.
 * Serpent reveals his knowledge of the Biometal and says that he's also a Mega Man, possessing Model W. He expresses his intent to find the Model W Core, and leaves, but not before possessing a weakened Giro with the power of Model W. A fight ensues, mortally wounding Giro.
 * Giro hands Model Z over to Vent and Aile during his dying moments and transforms into a Cyber Elf. By "double mega-merging" with both Model X and Model Z, they use the form Model ZX to escape.
 * Now the Guardians, including Vent and Aile, must recover eight Biometal fragments and stop Serpent.
 * After finding four of eight Biometal pieces, the Guardian HQ comes under attack from Mavericks, led by Prometheus, with Vent and Aile aiding in the defenses. They succeeds in defeating Promethus before recovering the rest of the pieces.
 * Upon retrieving all eight Biometal pieces and their passwords, Vent and Aile is able to enter a secret location and find Model W. However, Vent and Aile is stalled by Pandora and the Biometal is moved elsewhere.
 * Later, Vent and Aile receive a signal from Model W, located at the Slither Inc. Head Office. Vent and Aile set off to destroy Model W.
 * After battling through Slither Inc., Vent and Aile face off against Serpent, who feeds the Model W core with several innocent Cyber Elves, and then fuses with it.
 * Vent and Aile suddenly reverts to human due to the realization that the hatred of the Mavericks that they have kept inside their heart is the last thing needed to unleash Model W's full power, thus resulting in their temporary defeat. However, after gaining courage from the Biometals, they merge into Mega Man ZX and challenges Serpent to a final battle. During the battle, the tower collapses, destroying Model W and killing Serpent.
 * Vent and Aile reunite with Prairie and the Guardians, and vow to continue to work for peace and justice.
