Plot and Summary of this verse

Power of this verse
Yu Yu Hakusho in terms of power used to be well above the HST, but not anymore, the verse is above One Piece, but below Naruto and Bleach (due the Narutoverse got crazy powers up and better destructive capacity feats than YYH showed, and Bleachverse because they got crazy hax techniques). There was a time when YYH characters were often used in battles against DBZ characters, due to the idea that both had similar fighting styles, but unfortunately YYHverse doesn't pack the power to really contend to DBZ even at the Saiyan Saga. Mostly End of DT (Dark Tournament) characters are mid tier One Piece level and end of series characters such as Yusuke are able to possibly continent bust and lower tier characters such as Sensui are able to possibly country bust, which leaves this series with multiple Alpha Level Mutants but nothing more powerful than that I'm afraid.
