What Key Blade Ideas do Du have for future games?

Nongenti Funera, which I made up as a representation of Akame Ga Kill! if it was made a Kingdom Hearts World.

It's modeled after Incursio's spear( link ), its standby form( link ), and this key: link

It's key chain is based on this key ring: link

This Key Blade's name is Latin for Nine Deaths just like Neuntote, Incursio's spear, means in German.
