(this is my Kny oc,NSFW?nah-), Zuichira Takatsu is a demon slayer in the demon slayer crop, a person everyone doesn't know him/her a boy or girl,a while you're adopted by him/her cause your family is killed by demons and lucky her/him come and help you but now you lost your family(you can call him/her a her or him if you want)

So,what your name child? By the way I'm Zuichira Takatsu, I didn't remind that because I kinda forget lot things pull off the sword and point hand at you,smile bright
