Kekkaishi

If you liked Bleach, you would like this Kekkaishi because there just ain't no way around it: if you enjoyed watching Yoshimori running around killing off demons, you're going to love watching Ichigo do the same. Bleach is just a little more mature version of Kekkaishi.

Both Bleach and Kekkaishi are about superpowers, and both have a progressive plot with viable bad guys. Also, both series have a main male character with a self-burden of protecting his friends, specifically close female friends. Ichigo has Inoue and Rukia (Bleach), whilst Yoshimori has Tokine, his close childhood friend. Both series are also manga-based.

Both Bleach and Kekkaishi run with the same idea of being a Shonen series. They are both about fighting demon like entities which later band together in an organization against the protagonists. There are lots of different characters with back-stories to learn about in each series. The main characters both want to protect someone they care about, especially a female friend.

If you like Kekkaishi and you are looking for a similar anime, then most probably you are going to love Bleach. Bleach is an anime about a young boy, fighting wierd creatures. Just like Yoshimori, Ichigo, the main character of Bleach, is what we can call a "baka" who, however, has monsterous strength and a lot of determinatio! Ichigo feels the nedd to protect those important to him, as Yoshimori in Kekkaishi does. Well, Bleach is a great choice, thus I say you try it!

there both about high school kids fighting demons.

the main characters both start out with an overdoses power and hidden potential but without the ability to use there power effectively and there main drive is to protect the people around them.

If you like action-packed shounen filled with characters who possess supernatural powers, then Bleach and Kekkaishi are anime for you.  Also, Ichigo of Bleach and Yoshimori of Kekkaishi are very similar in personality. 

Bleach and Kekkaishi center around a grumpy, spirit-world-sensitive high school student with special fighting abilities, tasked to secretly protect those around him w/ the help of some unlikely friends. In both series, spirits and spirit-world drama and mysteries propel the plot, while the uniquely high-powered hero (Ichigo, Yoshimori) hones his skills and learns to better defeat his opponents and protect his friends and family. Though Bleach is much longer, more complicated and violent than Kekkaishi, which keeps its world a little smaller and focuses more on the relationships between the leads, they have similar sensibilities. 

Well for starters both Kekkaishi and Shounen Onmyouji are about teenage boys who spend their nights vanquishing evil spirits who look like monsters. While Yoshimori is followed by a ghost wolf named Madarao, Abe no Massahiro is followed by Mokkun. The similarities don't end there either; both come from families with a sworn duty to protect something. While they may differ in character personalities, the only real thing that separates them is time. Therefore, anyone who enjoys Kekkaishi is surely going to like Shounen Onmyoji.

Fighting demons, exorcising monsters, both anime have this and more. Young boys with a demon partner fighting invisible demons is the premise in both. If you like action and good old fashioned japanese demon fighting, both of these anime are right for you.

Both animes are about young shamannic power users who \\\\defend a certain place with their power. Furthermore, if you liked the era and placement of the action, both animes are suitable for you to watch.

Both fall into the category of a shonen anime, and both deal with battling as the main subject for each episode. Also InuYasha, and Kekkaishi each share trace ammounts of Romantic feelings between the male and female protagonists. However Kekkaishi's romantic side is much more like a light crush. If you like one, you will be sure to like the other.
