Yu Yu Hakusho 120-End
Man...
Going through YYH after rereading HxH is kinda sad. Gods. So many elements in common, so much stuff that was just lifted or mildly adapted. That same worsening of quality as time goes by....
Then you hit the final arc in the demon world, dude calmly introduces the characters, sets up their personalities and backstories (pretty well done bit for a shonen title, tbf), and, as soon as Togashi starts once again going crazy with all the tournament rules and all the crap he loves so much, something happens and he just gives up on the whole thing. Deja vu hits hard.
Can't help but wonder what finally caused him to give up on the book. Inclined to believe that he didn't wanna pump out tournament arc after tournament arc, but... he then went and did HxH right after, so...
