Azrle, a being born from the fusion
The battle between Jupiter and Azrle looked quite intense at one glance, but in reality, the deity was losing against the mortal.
Whatever attacks Jupiter was using, Azrle was blocking them with the shield, where the Jewel of Earth was embedded. Azrle's attacks, on the other hand, were wounding the former.
Pluto's essence was making sure not to let Jupiter's wounds or his energy recover while Neptune's essence was rendering his body's defenses, useless.
Azzy's durable body, inexhaustible stamina, and powerful sage core made it easier for Azrle to launch sealing techniques from Leah's memories that the latter usually couldn't, due to her feminine mortal physique.
The battle went on for an hour, and Jupiter looked anything but fine, filled with injuries and wounds from top to bottom while Azrle looked very imposing.
