Both series revolve around asocial male leads that are tricked/forced into joining a club. They also have a female lead that drives their male counterpart to perform club tasks and, surprisingly, do a good job while he is at it. They are also both high school comedies with hints of romance.

These two have the genre mystery in common, thrown in with a few 'awkward, possible romantic' situations. Basically, if you like mystery, watch Gosick and Hyouka.

Judged by how character setting is almost man-to-man similar, can't refuse that it will make the overall mood and tone similar too. That's how it's happening. The leading male and narrator, Kyon and Oreki Houtarou, are made from the same mold. Average, not standing out, and does not want to take initiative whatsoever in school activities. And guess what, they are getting pushed around by girl of course, The ultimate reason why any straight man go out of their comfort zone.

When looking at the artwork for Kokoro Connect and Hyouka, the artwork looks strikingly similar to each other, despite being animated by differing studios. Hyouka's artwork is a marvel to look at since it was animated by KyoAni, but Kokoro Connect's artwork is also very good. Kokoro Connect, synthesizes comedy and drama in a very appealing way. It does not rely on straight gags, and it doesn't try too hard for laughs. This is a positive, because it doesn't seem forced like in other anime. The drama is not over the top and does not seem forced at all. There are also slice of life elements  read more

Oreki may as well be Tomoya and vice versa. They have the same seiyuu and behave and think in largely the same manner. The main heroine in both shows is also there to serve as a foil and contrast for the protagonist and the style and tone of the two anime is very much similar. While Clannad is much more serious and dramatic than Hyouka is, there's something for fans of either show to enjoy here.

These series are not about spectacular murder cases, but rather about the mysteries of everyday life. They turn the ordinary into something special, relying on atmosphere and scenery to draw in the audience. The 'cases' (if you may call them so) are small in scale, but both series show the emotional impact that they make on the involved characters.

Hyouka and Sakurasou have very little to compare regarding their cast and their plot. Both are great in production quality and execution. However, their biggest similarity is that both tackle the thematic element of the "genius". Both series question how unfair it is for people to simply be more talented. Certain characters, like Satoshi from Hyouka and Sorata from Sakurasou, become frustrated with their talents compared to geniuses like Houtarou and Mashiro, who seem to accomplish things as if it were second nature to them. Both also show the flipside of the coin and talk about how even geniuses are nowhere near perfect. For example, Mashiro  read more

Under the same director and animation studio, we are presented with a bored, cynical, and generally unsociable male protagonist who is largely uninvolved with his high school life until his encounter with the eccentric and emphatic female protagonist whose request for help pulls them into an adventure they would never have experienced otherwise. Initially, both protagonists are reluctant to help, but continue to find themselves becoming more and more involved and even attached to the people he made friends with.

The aura of the to shows are similar. Even if the stories are quite different, but they both have the same slow tempo with a lot of explaining at it's center.

Hyouka is an adaptation of the Koten-Bu Novel series, beware that it doesn't have an actual conclusion. It's similarly slow-paced and character driven narrative nestles it into the same niche as Hana to Alice. Hyouka utilises mundane mysteries--which are great on their own--as a backdrop for its characters. Hyouka has similarly high-production values and the same sort of deadpan humour, with distinct and unique characters.

After a session of careful thought, you can see that what the lead male characters are doing is pretty similar. Presented like there are something supernatural going on, both shows are about myth busting in a world without the slightest existence of sci-fi elements. It's all about the idea of unconventional presentation of a very conventional, realistic setting. Denpa Onna anime, as far as it goes, has nothing defying the laws of physics.

The main characters are also kind of similar in that they don't like getting involved in certain things. Both of them are also done by the same studio so they have similar character designs and they both have a lot of romantic relationship building without any progress (if you're into that thing).

Hyouka shares with Nana Maru San Batsu the underlying theme of how individuals deal with information. Instead of taking a competitive spin on this, Hyouka takes the detective-genre route. It is still about everyday high schools who take apart questions that don't seem to be like a big deal and try to come up with satisfying answers. This time however, the questions aren't coming from quiz booklets but from the students themselves.

If you take a look at the premise and synopsis of both shown, they are nothing alike. However, if you start watching them, you'll find that the protagonists of both shows are, at heart, the same: Kirino and Houtarou are willing to open their true selves up, after getting a little push from someone close to them, or someone being curious. If you liked the steady development in characters, or just seeing two completely different personalities interacting with each other and learning about themselves, you'll probably enjoy Hyouka and OreImo.

Both shows have a similar structure and general tone. The stories are told from the perspective of a "straight-man" main character, who reluctantly gets himself involved in the shenanigans of a curiosity-stricken female lead. The supporting characters also show a number of similarities between shows, and both also offer the interesting narrative quirk of adding the main characters thoughts to spice up the dialogue. Though Haruhi is more upbeat than Hyouka, both make for a wonderfully interesting experience.

Although the concepts are completely different the main characters are very similar. That being; Ryner & Houtarou want to spend most of their time doing a limited amount of things and being lazy. They are also both forced off their backsides by each of their own main heroines to do something useful with something that they don't tend to use too often. For Houtarou his detective ability that he never really used because he is lazy like that and for Ryner his eyes that pretty over powered.

D-frag and Hyouka both have a central focus on an obscure school club that goes through adventures and bonding time. The MC in both shows are dragged around by the female lead. Finally, both shows do not really have a central story to them, just a group of friends going about their everyday life. However, in Hyouka, they have a more serious/mysterious atmosphere, while in D-frag, the things they go through are mostly for comedic value/entertainment.
