Why HxH is tailored for mature audiences

Hey guys upon recalling some scenes and going through my hxh manga I started to realize and understand a lot of things throughout the story that I didnt really click with or understand as much beforehand, this led me to the idea for this video! I got a mixed ish consensus when I asked around in regards to my friends opinions on the maturity rating they believe fits with hxh so im excited to see what you guys think. Let me know in the comments!
