The main reason i recommend watching it is the artwork and lovable characters. Have you ever wondered what would happen if you turned beautiful anime fan art into a animation? Well the K series is the answer. K return of kings just shows off with its stunning lighting and beautiful supernatural chaos without a harem or douchebag main character to go along.
The characters are also loveable with Shiro being the funniest, kindest and friendliest MC I can think off of the top of my head. Neko and Kurou are also great characters along with Fushimi and Mikoto. All of them could make you cry or laugh at the drop of a hat.
I extremely recommend this anime even if it has room to improve you will have a great time watching it. I may be an optimistic reviewer but I guarantee you will enjoy this anime and the other ones in the series.
(You should definetely watch the previous series to catch up on the story, both are equally beautiful and you should e fine tell check them out.)
