Post Anime series that te think would not be as good without a certain Anime character in the series (give your reason please)?

Tokyo ghoul I think Tokyo ghoul is very good plot Its because of the major influence and story of ken kaneki his adventure on becoming a ghoul and adapting through it while getting caught in a war between CCG and Aogiri albero without Kaneki I think The Tokyo ghoul series will become less interesting and mostly likely just a war between Aogiri albero and CCG with no plot direction I think Kaneki has huge impact on the plot of the series
of being good and interesting
