How many times have people told you "anime's for kids!" Well, I can list quite a few anime series that are Not meant for children.
- attack on Titans.
- Death note
- The promised neverland
the list could go on, but I won't drag this on for too long.
Anime can be romantic, suspenseful, action packed, etc. there are so many genres of anime. I'm a fan of different types of anime.
long story short it's like telling someone that cartoons are for kids or video games cause violence. Which none of those things do.
