After the world is ravaged by a pandemic the government starts culling people who show signs of infection; and even some that don't. Understandably, this doesn't sit well with everyone. Due to the death toll, Funeral Parlor is created to oppose the corrupt government. Everyone isn't keen on violence, though. Take Shu Ouma, for example; Shu is consumed by fear, runs at the first sign of danger, and he hates himself for it. Uncharacteristically, Shu saves a beautiful girl named Inori Yuzuriha. Inori injects godlike powers into Shu and he is now faced with a choice to fight with Funeral Parlor or to flee. Of course, no matter what he chooses to do everyone will be watching him closely.

Guilty Crown and K share similarities in the action and main protagonists. Both anime have characters who use superpowers to battle. Both anime also have a serious tone in story. Shu and Yashiro (from K) are forced into situations they cannot control. For example, Shu is injected with a genetic weapon, and Yashiro is framed for murder. Control wasn't something either character had under those circumstances. Guilty Crown provides a great viewing experience from director Tetsurou Araki.

Ikebukuro is a downtown district in Tokyo where gangs gather and undesirable things tend to happen. Mikado Ryugamine makes contact with an old friend and decides to move to the district, where he witnesses all sorts of things on his first day.

The urban legend's name is Celty Sturluson (a Dullahan), and she is searching for her head. Most of the people Mikado meets are into some shady business. Of course, where there is shady business, Celty usually isn't too far behind.

Durarara!! is an intriguing mystery-action anime with a serious tone like K and features gangs in conflict with each other. Yashiro and Mikado both hide secrets too. Yashiro never tells people he's really Weismann until later in the series. By comparison, Mikado never tells anyone he has a dark side until later. Both characters also seem to gloss over the seriousness of their situation. Durarara!! also features multiple producers such as Square Enix and voice talents like Johnny Yong Bosch (Dub). Durarara!! is adapted from the light novel written by Ryohgo Narita, so if you're into mystery-action you'll want to watch it.

K and Bungou Stray Dogs are both mystery-action anime, and both of them have beautiful animation. There is, however, one major thing that K and Bungou Stray Dogs have in common.

Yashiro, for example, is wanted for murder; and Kamui is sought after because he is destined to fight for Earth's destiny. There are, however, similarities between the main protagonists. Both Yashiro and Kamui are faction leaders who wield incredible power. If you liked K, then X is a must see! X TV is directed by Yoshiaki Kawajiri (Ninja Scroll).

But one similarity stands out above the rest. Stalkers are people that no one wants, but some people have to deal with them.
