Modern society has many holes, and SZS jumps right into that hole with details. Our MC, which is Itoshiki Nozumu, explores those holes with heavy, sometimes dark jokes. It is very common not to understand those jokes if you are not from Japan, as most of them are references to Japanese society, though they may also apply globally. For the most part, the plot is conveyed in episodic format. Yup, "for the most part". There's a teacher and a few students who explore the world with their own distinctive viewpoints. The Surreality of this manga is amazing. One more thing is that this manga is loaded withmany dialogues.
Moreover, there's a lot of references spread throughout the manga, which you don't want to miss.

Talking about the characters, they all have different traits and are interesting in their own way.
The author didn't hesitate a single bit to make fun of himself, his editor, and his assistant. He also mentioned a lot of things from his past work.
Lmao, he made jokes about his past deeds too.

Overall, this manga is awesomely hilarious, filled with dark jokes and satire and lots of "fun events.".

P.S.:
I'll just say one word: "The Ending."

That's it. Enjoy and have fun.
