Now i don't know if this is counts as an anime, or more like animated video series with japanese style art.
But it is called the Onibi series, and i found it a while ago and it seems quite interesting. It is a series made by Masa
there are a lot of theories surrounding what the series is about. But there is some profanity and gore involved, i can't lie.
At your own risk i picked out some videos i liked personally.
Yea the videos are pretty fast pace, But when i listen in i find parts i like and i try to memorize them.
The series interests me, And i like Masa's art style. All so different
