Alright, after reading i have noticed this manga has few references to some manga such as Death Note which is the most notable.
I noticed a Kaiji reference where students were playing a card game with the Emperor and Slave, those who have read the skyscraper arc or watched the anime know what it is xD

And from the forums i saw that some people noticed the oddest of references such as facial of Nero and Suzumiya Haruhi, what i want to know is if anyone noticed any other hidden easter egg 🙂

There are a reference when Kurosawa really want the voice changing device which is used by an "idiotic detective", said him. 🤣
You know, "the Barbarian" Detective. 😛

Oh, and these :

I couldn't help but see a similarity xD

Compare Kurosawa here:

to

Nougami Neuro:

They're basically the same @_@

Ha, ha... Yeah, there's at least one shout-out per chapter.

The one that sticks out for me is this one When I first read OMK, I saw that page and knew it was a reference, I just didn't know to what. Then a couple years later, I randomly decided to watch Code Geass and went "THAT'S IIIIIT!!!!" when I saw the end credits.

And because it seems appropriate, here's a picture of Lelouch Suzumiya

Are there any other manga with similarities with Onani Master Kurosawa that you could suggest?
Somehow, I like it when the final pairing is hard to be predicted.
