A time travel card triggers a cliché time travel and Hisoka becomes Hisoka Dumbledore. When Hisoka Dumbledore meets Tom Riddle, a senior Death Eater? Order of the Phoenix? Do two people who think they know Hisoka really know him? When a "bad guy" goes through a long period of time and has friendship, family ties, and even love, and then loses them all, will he become kind? There is such a soft place in everyone's heart. The sharp blade of time has torn away the surface strength, revealing a little bit of softness and kindness. CP Hisoka*Voldemort's time span is between the two century wars. PS The Hisoka in this article is after Greed Island and before the battle with the captain, that is, Hisoka is based on the old version of the anime.
