The male protagonists of " Fantasy Noble Son " and " Detective Yakumo " had different settings, but they all had one thing in common, and that was that they both had special abilities. There were also some characters in anime that were similar to these male leads. For example, Kimki Ken in " Tokyo Ghoul ", Tanjiro in " Ghost Blade ", and Allen in " Attack of the Giant " all had similar special abilities or background stories. In addition, there were many other works that had similar male protagonist settings, such as Kirito in the Sword God Realm, and the reincarnator Shirai Kuroko in About My Reincarnation as a Slime.
