If you want to read about Yugioh teaming up with Detective Conan and the Sailor scouts to battle Piccolo, then this might be the manga for you. If you want some nice soft core fan service, this is definitely the manga for you.
If you want consistent characterization, a relatable protagonist, story continuity, justice, a story free of political bullshit, a good ending, or just quality in general, this is definitely not the manga for you. If you want well thought out gambles / death games, analysis, psychology, or even just warrior’s spirit, this is not the manga for you.
Don’t let the first few chapters fool you, this one goes to shit fast and is looking for a 5-6/10 from me.
