Who doesn't love a crossover between their favorite isekai. I like how they mixed opening songs of both anime towards the end and drew parallels between the characters. (like how Epislon & Shaltear are both jealous) It was funny how Ainz roleplayed as a chunni to fit in as shadow, while Shadow being Shadow just let the situation play out. Everyone reacted in the way we expected them to. Honestly, I was expecting something like this to happen at some point because they were way too similar. And are both by Kadokawa. Hopefully this means we can hope to see shadow in the Isekai Quartetseries. This Ple Ple Pleases me.
