(Some spoilers) This story takes place somewhere in episode 25 titled, "Chinmoku". In my opinion, the series should've ended shortly after L had died. Having his predecessors finally complete the job that L wasn't able to so doesn't sit right with because because I've always seen Death Note as almost having 2 main characters and displaying the story of Light vs L, evil vs good, genius vs genius. I'm not saying the rest of the episodes were bad, I enjoyed the thrill but I just didn't see the point of continuing. I felt that because the series starts with Light and L, its should end that way too. So this story is somewhat based on that, its not the best but it does have meaning and portrays a more meaningful ending. Happy reading!
