If you liked the Nabari no Ou anime, the Anime-Planet community thinks you'd like:
Ban Midou and Ginji Amano are the Get Backers. With a 99 percent success rate in returning lost or stolen property to its original owners, they will do anything for the right price. Midou and Ginji often get hired for seemingly ordinary jobs that turn out to be more difficult than they appear; and whether it’s finding a doll for a girl, retrieving a stolen rare violin or getting mixed up with the mob, they have many adventures with plenty of petty squabbles along the way!
Although the two shows are based on very different stories, they both have the same fun filled mix of excitement,comedy and action.
There are a lot of similarities in the bishounen and bishoujou characters, enough to make any fan girl/boy's heart skip a beat. The characters are all lovable, and easy to relate to. The fight scenes are well drawn, and impressive in both shows. Neither Nabari, nor Get Backers feels the need to have super charged up attacks, or an overpowered boss of the week.
The story in both is engrossing and interesting, and I think if you enjoy one, the other is sure to follow.
Brandon Heat and Harry MacDowel were best friends who lived by the law of the street, until one day they picked a fight with the wrong people and their life of freedom was suddenly taken away. With no one to turn to and nowhere to run, the choice to join Millenion, the city's most powerful syndicate, seemed like an offer they couldn't refuse. Now, amidst heartache, tragedy, and utmost betrayal, Brandon must take up the gun and help Harry climb the ranks of Millenion to succeed, in order to protect the people he loves, even if it means killing countless others in the process.
If the deep friendship Miharu forms with you-know-who (don't want to spoil) warms your heart, you may want to check out Gungrave, an anime driven by the character development of friends Brandon and Harry. The other similarities are very thin: yes, both have action, and yes, both are about some sort of underworld - one shinobi, and one mafia. But the piece that made me want to recommend Gungrave was just the friendship.
Different characters, very different stories, even different target demographics, but a similar heartwarming connection. If character development and interaction makes an anime good for you, then I simply must recommend Gungrave (though be warned that Gungrave is TV-MA, compared to Nabari no Ou's TV-14).
Middle school student Tsuna has always gone through life in last place; but when he learns that he is getting a tutor to help him raise his game, he had no idea that his benefactor would turn out to be... an infant and a mafia hitman?! As if things can’t get much stranger, Tsuna then discovers that the powerful Vongola family has chosen him to be its next successor – a position that has control over all mafia families. Joined by friends Tsuna unwillingly starts out on his path to becoming a mafia boss – if he can survive the training!
Sumimura Yoshimori is a Kekkaishi – an inheritor of the power to battle demons, using barriers called kekkai. His family is charged with protecting the grounds of Karasumori high school, a building which magnifies the power of demons who enter it. Helping him are his spirit-wolf companion Madarao, and next door-neighbor Yukimura Tokine, the daughter of a rival clan. Years ago, Tokine was injured protecting Yoshimori, and now he is determined to become strong enough to keep her from being hurt again. Of course, he'd rather bake his exquisite cakes than have to fight demons at all, but fate has something else in store! As a shadowy demon organization moves to steal Karasumori's power, can Yoshimori overcome legions of demons, a centuries-old family rivalry, and a grandfather who just can't understand his love for baking?
They are both similiar in many ways, having characters similiar to each other in Nabari's case yoite and Gen

this causes them to become very estrangled teenagers and both end up having extremely low self esteem.
The main characters also both have a power in them that is unique to them and is very powerful.
Yoite and Gen: they both end up finding something that they were truly looking for
