Azure Striker Gunvolt 2

Gunvolt is given a new outfit by Quinn and Xiao, and the trio outline four members of the Seven to investigate and take out. The first, Gibril, is a young punk girl whose septima, "Metallon", allows her to create bladed weapons through metal, especially via hemoglobin in blood. The second, Milas, is an environmentalist who uses his "Ichor" septima to control and freely move through water to deliver deadly attacks. The third, Teseo, is an internet troll and black hat hacker who constantly harasses Gunvolt and Joule, and can use his "Hack the Planet" septima to digitize and destroy reality. The fourth, Tenjian, uses his "Permafrost" septima to attack with deadly ice blades and sub-zero temperatures. En route to Tenjian, Gunvolt runs into Copen and is forced into battle with him, but Copen breaks and retreats.

After killing the first four members of the Seven, Gunvolt is sent to a highway in the city by Xiao, where he runs into Copen again, as well as a fifth member of the Seven: Ghauri, a street dancer and slam poet who uses his "Prism Cataclysm" septima to create deadly crystallized weaponry. Copen retreats again, leaving Gunvolt to deal with Ghauri. Gunvolt makes short work of Ghauri and returns to his apartment, where Xiao reveals that he's located Eden's fortress, the Garden, in a remote nation called Tashkent. The two head off to take out Eden once and for all, while Quinn stays to watch over the base. In the fortress, Gunvolt finds and eliminates the remaining Seven members. Deep within the fortress, he encounters Zonda, who battles him in her illusory forms, but when Zonda shatters, Gunvolt deduces he was fighting an illusion. Continuing on, he finds Zonda in her young girl form, who has Mytyl captive and unconscious. Zonda explains that Joule and Mytyl are two halves of a whole; Joule was the adept part of Mytyl removed in an operation that left her mute and sickly, and cloned into her own body by Sumeragi. Using Mytyl as a proxy, Zonda rips Joule completely from Gunvolt's septima and uses her to power their own septima to unspeakable levels and transform into a deadly demonic form. Undeterred, Gunvolt manages to fight and kill Zonda for good, but at a cost: Mytyl has died thanks to Zonda, and Gunvolt curses himself for allowing an innocent girl to die. Copen arrives on the scene, and seeing Mytyl dead, swears to Gunvolt that he will kill every adept on the planet, starting with him. The two face each other in a Mexican standoff.

Checking in with Mytyl, Copen's robotic partner, a sentient weapon pod he named Lola, suddenly projects a humanoid female form, much to Copen and Mytyl's shock. Copen deduces that the shards he was collecting from adepts is the cause, but is puzzled by its occurrence only around Mytyl.

Copen and Nori outline four members of the Seven to investigate and take out. The first, Desna, is an amateur astrologer who attacks with living hair brought about by her "Splitting Ends" septima. The second, Asroc, is a former pastry chef who can control machinery with his "Puppetmaster" septima. The third, Ghauri, is a street dancer and slam poet who uses his "Prism Cataclysm" septima to create deadly crystallized weaponry. The fourth, Tenjian, uses his "Permafrost" septima to attack with deadly ice blades and sub-zero temperatures. En route to Tenjian, Copen runs into Gunvolt and is goads him into battle, but Gunvolt breaks and retreats.

After killing the four members of the Seven, Mytyl is kidnapped by Eden. Copen is forced to chase down two of the members, Gibril and Teseo. He corners both of them in the sewers, where Teseo tells Copen that Mytyl was sent to their fortress, the Garden. Gibril sends Teseo off and confronts Copen, but Copen manages to kill her. He returns to base to determine the location of the Garden with Nori, and locates it in the remote nation of Tashkent. Traveling to the Garden, Copen destroys the remaining members of the Seven, and encounters Zonda once again in their bigender form; however, when Zonda shatters after battle, Copen realizes he was fighting an illusion. Continuing deeper into the fortress, Copen encounters Zonda once more in their little girl form, who has Mytyl captive and unconscious. Zonda explains that Mytyl is an adept, and that her adept half was removed and cloned as Joule; the trauma of the operation left Mytyl mute and sickly. Copen is shaken beyond belief at the notion that his sister is an adept, and Zonda uses Mytyl as a proxy to rip the power of the Muse away from Lola, transforming into a horrible demonic form. Copen manages to kill Zonda after a ferocious battle, but at a cost: Mytyl dies from the severe strain. Copen has a breakdown and swears bloody vengeance to all adepts, innocent or not. Gunvolt arrives on the scene, and the two are locked in a Mexican standoff.

When both paths are completed, the final act of the game sees Gunvolt and Copen locked in a standoff as before, but Copen instigates that every adept must die, no matter what. Gunvolt tries to sway him out of killing adepts, and the two engage in combat with one another until one of them is killed. At that moment, Mytyl revives, demanding that the two stay away from one another, and surrounded by the power of Lola and Lumen, she revives the fallen warrior, whose power is amplified to its utmost limits, and the two battle each other to absolute exhaustion. However, they decide not to kill one another, thanks to the words of a revived Mytyl, now reunited with the essence of Joule and having regained her voice once again, but losing her memories of the two.

In Gunvolt's ending, he and Quinn are out together, when he has a chance encounter with Mytyl, who stops, puzzled, and asks him if he's an angel, echoing Joule's first words to him. Gunvolt kindly tells her he's not, deciding it's for the best that she never remember him again.

In Copen's ending, Copen decides that he can no longer be around his sister again, and asks Nori to tell his sister that he died in combat. Nori asks him what he will do, and Copen tells her that he needs to search for answers, but he cannot face his sister, now knowing that she's an adept.

In a post-credits scene, Mytyl is shown to be happy at last, although she occasionally has dreams about Gunvolt, revealing that Joule's memories still live on in her. She hopes to thank Gunvolt personally one day for everything he's done for her.
