Dawg I dont think u understand black representation has been put in litteraly almost everything, modern shows games name it. In the west there is 100% more black characters in your show then white at this point.
Do you think people are getting tired over nothing? There is a reason why the original comment was lamenting about this.
Also a quick google search gives you all the info you would need. The shinsengumi were a group full of asians, none were black or even darker skinned.
If they wanted to implement a black character they shouldve just done it with an originally back character, because I do get that this about humanity and that would indeed mean black people should be represented aswell. But the way it was done just seems very stupid.
They couldve put Frederick Douglass in there or something, but this is just stupid. He**, just put Lebron James in it.
