Darker than Black: Kuro no Keiyakusha, Durarara!! Recommendations
Two of the darkest, supernatural AND mystery genera that I know of. They both use a lot of dark lighting for their night scenes, and a lot of light, when it comes to the day time.
similar calm and steady plot and feeling of mystery about them
The animation is very similar. Also the way the episodes can shift between the different characters, focusing on specific people for certain episodes. Celty also reminds me of Hei, the main character from Darker Than Black. Both not exactly human. Both seen as kinds of monsters. Both have good hearts deep down and discover this throughout the show. Both are total badasses haha.
If you love Durarara, then you'll totally love Darker Than Black.
They're both amazing animes ^^
Same type of dark space and people with special powers. It's also very exciting, with a mysterious plot and also to mention; on a screen in Durarara!! they show a picture of Darker than black Ryūsei no Gemini.
Both Anime's are extremely dark, both have powerful plots that are hard to recognize at first. Like "Durarara!!" "Daker than Black" has a very scattered plot at first and the later episodes tie it all together, making even things that seemed to be fillers tie directly into the plot.
They both have a dark tone with the supernatural setting.
Durarara! and Darker than Black both follow several main characters but focus mainly on one male. Both contain supernatural phenomenon and people such as Dullahons and Contractors. Both of the animes mentioned also focus on gangs or organizations and include a substantial amount of violence/fighting.
Darker than Black definitely had a very similar feel to Durarara!! They both have mythical character and gang aspects to them. They were also not completely serious, with moments of lighter comedic scenes. I feel like they both used a darker tone in the artwork that was also very similar.
The similarities start by comparing the setting of each anime. Darker than black revolves mainly around the contractors and their connection to the mafia, somehow I even would compare this to batman (even though I've never watched it through). In Durarara likewise there are the gangs and the struggle of each character against it.
Similar yakuza themes, as well as badass characters.
