What ideas do u have for Non-Standard Game Overs: link

One idea I've had is in a world based on Akame Ga Kill!.
It wouldn't happen if anyone you're escorting in this world dies, instead they would die for good(That's how death works in Akame Ga Kill!).
Rather it would happen in a task u would have towards the end on Sora's route where u must keep at least 50,000 rebel soldiers and 10 Teigu users(including Akame) alive door the time Sora and co. reach Esdeath.
If u fail any of the above criteria for the task, it's game over.
