Who created Demon Slayer ? I do not know and I do not care , I am in 6th grade learning to be a publisher. but I do want to , but anyway lets talk about the anime it is a great anime but lets talk about the charaters first up is rengoku he is the fire harshira but lets be real you guys he literally got beaten by an uppermoon demon so he is not really special , next lets talk about tengen first hes really cool and he has three amazing wives so basically hes cool; But please make sure not to make zenitsu jealous. That brings me to the next one zenitsu and he is a scardy cat but is very when it comes to protecting nezuko but yeah he uses alot of his forms so out of the kamado squad he is the second strongest ... After him is nezuko and she is extremely strong for a demon she should literally be the next uppermoon demon but yeah she defeated an actually uppermoon 6 demon and regenarated but then she almost ended eating a womans arm but thankfully tanjiro saved the woman by blocking her mouth with a sword. Next is tanjiro and everyone has said that he is the next demon king but still is strong, some people that hes strong even without his form . Last but not least is mitsuri she is extremley my bestie but button up your shirt. And thats it.
