"The elevator to Firmament has become a river Styx. One by one, condemned souls return from the netherworld..." - Flavor Text
Babel (アメノサカホコ Heaven's Inverted Spear) is a mission in Azure Striker Gunvolt, codenamed "Stratosphere". Having successfully hijacked the space elevator, Gunvolt must ride all the way to Sumeragi's space station Firmament.
Moniqa: The orbital elevator "Babel"... Looks like you made it in one piece. Zeno: We got full control now. Hope you're ready for some elevator action. All that's left is for you to go bring Joule back home. Hop to it, man! Moniqa: This may be all under control, but you're still in a Sumeragi facility... Anything could happen... Keep your guard up, OK? Gunvolt: Got it. I'll be careful.
The stage starts off with Gunvolt riding Babel up to Firmament. As he does so, he is ambushed by Stratos, Jota, and Viper in that order. Once he makes it to Firmament, Elise then attacks him, this time accompanied by her crazed third alter, who was responsible for reviving the aforementioned members of the Sumeragi Seven. After the two main alters are defeated, the crazed one revives them as well, and attempts to do so a second time before being shot by a Power Grab bullet, killing her. Copen then reveals he was the one who shot her, and demands a rematch with Gunvolt. Even after using the powers of every member of the Sumeragi Seven, he is still defeated in the end, but Gunvolt spares him and rushes to save Joule, ending the level.
Boss: Copen "The Adept Slayer" #2
At the end of the stage, Copen is fought once again. This fight is similar to the one in Sinner's Row, except now Copen will use the abilities gained from every member of the Sumeragi Seven, including his most powerful skill, Doppler Desire. This attack can only be avoided by using Air Hops, defeating Copen before he dashes forward, or by destroying at least three of the copies Copen creates. Other than that, the strategies that worked on Copen in Sinner's Row work just as well here.
