Anime is one of the most diverse art forms in entertainment. There are series with wonderful highs, brutal lows, and everything in between. Some series have a little bit of both, starting with light-hearted fun before quickly venturing into vicious territory. There aren’t many more twisted moments in anime than those with a quick, dark turn. These turns are usually entirely without warning, stunning audiences with brutal events that nobody could have seen coming.
