Anime has taken over western pop culture in a way that wouldn’t have been believed some 30 years ago. While it was available, it was very limited to select channels.
Now, adults are tuning into mostly Japanese anime series like Attack on Titan, Shigurui, Cowboy Bebop, Berserk, Ghost in the Shell, Death Note, Hajime no Ippo, and most recently, Cyberpunk: Edgerunners.
The genre is only becoming more popular, which is spilling off into other lines of entertainment. There are plenty of anime casino games out there now, and in the right places, you can play free anime-themed games.
