Dakara Boku wa, H ga Dekinai.

In both: -Main normal guy which loves erotic things and has the special powers. -Main girl is from underworld demon. -Similar art. -No censorship on the chest and pants. 

A perverted male protagonist with a female protagonist with supernatural abilities, also surrounded by female characters with abilities as well. Fight scenes. Fanservice... rest is history :) 

Main female characters both have red hair. Both use fire with their main weapon and both make an alternative dimension when fighting against the enemy. Also, both main female character tell the main male character that he will not live for very long. 

The lead males are very similar. They are shameless perverts, very honest, and can be very manly when the situation calls for it. The lead females are also similar with respect to their insecurities. They also have a similar nobility background. There is also the fact that the leads in both anime are bound by contracts. 

Similarities: Both have the same school, magic, supernatural and ecchi genres. Both muchachos (male lead) have childhood friends who literally takes care of them. Both have the same situation where the a mysterious magical girl approaches the muchacho (male lead). Both have the same members of the muchacho's harem whom would at first be the enemy before warming up to the muchacho. Dissimilarities: The chiquita (female lead) in one anime is a tsundere while the other chiquita (female lead) from another anime is a tease. The chiquita (female lead) in one anime treats the muchacho (male lead) like shit, while the other chiquita from another anime treats the muchacho (male lead) as her master. The childhood friend in one anime is sweet, caring and has big bouncing melons, while the childhood friend from another anime is also caring towards the muchacho but always displays jealously and has pancakes. The chiquita (female lead) in one anime relies on the muchacho for an extra boost of power when fighting or using her magic, while in the other anime the chiquita (female lead) may not rely on his master when she's protecting him, but she does depend on him to keep herself in check.  read more 

Blue pill can be expensive sometimes, just grab a blue comedy anime as a stimulant. Will only cost you some brain cells, effects aren't 100% assured. 

Incredibly similar in how both are ecchi/fan service supernatural anime's with demon characters having begun to live in the human world due to certain [though different] circumstances. There's also a female tsundere MC with red hair in both. Differences mostly just being that Shinmai Maou no Testament is more harem based & the male MC's from either series having very different personalities.  

Shocking that these two weren't already recommended There exceedingly similar shows, i.e boy who happens to have special power meets girl in need, they're done in different ways however. In both stories echhi is a prominent factor (a plot device in dakara!) and both have action, however, dakara has more comedy, while freezing lacks in that department. However, the yang to the comedic yin, is freezing is wildly more gruesome with its violence, while as dakara's fights (while very common) often do not go to the extremes to which freezing went. 

Both focuses on the underworld and the supernatural. The girls main characters have red hair. Both of the boys main characters are perverts and has as its strength perversion. Both animes are somewhat eróricos. Both are cool XD 

I feel the same vibe both are with a main girl being a fighter from another world and both main boys being surrounded by many girls 

Both deal with demons and magic as well as demon contracts. Both also have their fair share of fanservice and harem genre. if you like one you will most likely enjoy the other. 

in both series the main is what you would consider as a pervert. in both series the main character appears useless , and is therefore often protected by the girls around him creating a harem setting. The fantasy and supernatural genre is very prominent in both these series , if you like on you'll probably enjoy the other  

Both anime have Comedy Ecchi Harem Both anime MC becomes more powerfull when they are perverted.  

Both are harem, but Dakara Boku, H ga Dekinai doesnt have chapters for every girl, it goes with one story 

It has a similar style in the sence that the main male character is supplying the female protagonist with some sort of life force or energy. Also the romantic relation between the two characters changes from initial hate to final love like relation in both series. 

Both mc are perverts but really like mg, both mg are not normal, although Akikan is more on comedy but u will like the other if u like one. 

I couldn't think of a better recommendation. These shows are ecchi, with similar joke styles, art styles etc. Furthermore the main female character is a demon, and the main male characters are surrounded by pretty girls. 

After watching the first 2 episodes I can say that this anime is somewhat really closely related to "So I can't play H" Especially how the two male and female protagonists relationship ended up. In "So I can't play H" the female protagonist (Lisara) lives together with the male protagonist (Ryousuke) and in "Chivalry of a failed knight" this also happens but instead the Stella and Ikki, the two protagonists, become roommates. Also the relationship between the male and female protagonists in both animes seemed really rushed and both contain heaps of fanservice that gets over the top to the extent that it makes me uncomfortable watching it. Maybe I'm just not a fanservice guy. Another similiarity is that the female protagonists are both red haired and they have fire as their magic power. They both also hold a fire weapon. One similiarity that I don't quite understand is that both female protagonists seemed pissed off and always act tough and walk away when the male protagonist interact with another girl, wether they're their sister or old friend. Also, both the ED's visuals are very, very similiar. read more 

Both anime are harem turned genres. The main protagonist is a regular high school boy who gets involved in something by accident. The "harem girls" are for the most part not ordinary and possess supernatural powers which are boosted thanks to main protagonist's "bodily fluids." (If you watch Dakara Boku wa, you will understand ;) ) Feel free to enjoy watching these two series. 

Both include magic and weapons, Both are action themed, Both include romance, Both have the real world and the fantasy/magic world, Dakara Boku wa H has ecchi while Mahou Sensou does not  

In both Haiyore! Nyaruko-san and Dakara Boku wa, H ga Dekinai, we have a main guy, who's living a peacfully life, untill aliens, demons and other monsters pops out everywhere. In Haiyore, we have get a harem with 3 alien girls (one is half girl half boy... depending on how you look at it), where 2 of them is fighting to be his love. In Dakra we get another harem with a main who is one hell of a perv, and somehow get quite a few lovers from that. Note that Haiyore is not an ecchi, it lacks fan-service, and have no plot. But it's one hell of a comedy :) read more 

The two male leads are perverted but surprisingly they also have a kind side to them, a side that the girls close to them begin to take notice of. 

In both: -Main girl is not just a normal girl. -No censorship on the chest and pants. -Similar art. -Main boy was just bored High School scholar.  

Both of these anime series consists of a single guy who after strange circumstances gets mixed in with the world of the supernatural and has his life changed like never before. Both series features the main male protagonist meeting other characters and forming bonds with them. Both series contains action, drama, comedy, ecchi, and romance. 

Both got this somewhere perverted main male character Both have got a harem Both got stubborn girls in them, that don't like them 

Both anime uses females characters with bracelets that grant them power. They are both extremely ecchi with lots of fan-service with the male protagonist at the center of attention like most harem. 

• Both anime are action with some ecchi scenes. • Both anime have supernatural powers. 

Instead of the usual bland and generic male protagonists we get super horny ones with a harem of super powered girls. 

Well it's like he's bound by Contract... and Lisara and Haqua kinda alike in some ways and they're both carrying scythe... and the protagonist both some kinda good and fanatic on their own fantasies... Also Keima and Ryouske have the same seiyuu
