A Cliché Multiverse Story

First of all Merry Christmas y'all, you cute bastards.

And no, there is no chapter today. I'm a bit busy over here. Now to the grit of things, I am here with a question. I was thinking of Akame Ga Kill as the next world after finishing the current with Danmachi and DxD world. Since AGK alone will be a bit underwhelming, suggest me some good manga/novel/games for crossover. A crossover could be whacky and a lot of fun.

Just don't say pokemon.
