SMT Nocturne X RWBY
After defeating the Great Will and restoring his world back to it's previous state of being before the Conception, Naoki Kashima had made peace with the fact that YHVH would forever him down for his defiance.
In fact, he'd made such peace with this fact that when he wakes up in the world of Remnant after a night of training(couldn't afford to get rusty with God himself trying to off you), he automatically asumes it's YHMV's doing.
Of course, that doesn't stop him from stubling his way into a war he'd no idea was being waged until he was right in the thick of it.
The God brothers sense a powerful force arive on Remnant, and decide to come back to the world they'd created in order to destroy it.
After all, those who meddle in the affairs of Gods deserve to suffer for their transgressions, no matter how slight the offense.
