Masou Gakuen HxH

These shows are about, powering up the female MC's through erotic stuff and at the same time male MC's are powering up too.Every now and then there will be a difficult situation but MC's will get through it by using ecchi power. 

Both main characters start out as decent gentlemen, with honest and sincere intentions. Both of them end up involved in lots of ecchi which is required/essential for the plot. Both series are heavily focused on the nudity-fanservice, which can go pretty much all out. Both main characters actually are useful in fights/major events (in most ecchi harem trash series the OP just stands there whining whenever something big happens), lots of other things in common, but I will leave that for you to find out As for the differences, Shinmai’s MC true powers are shown pretty early own and pretty quick rises to the OP badass character we all known from shounen, whereas HxH’s is pretty much a wimp early on. His potential is occasionally shown and foreshadowed, but he is mostly displayed as a catalyst for the female cast. Another difference is of course the setting. Shinmai is set in a similar world as the present, with the addition of demons and fictional races, whereas HxH is more of a futuristic mecha. One might argue Shinmai has more plot and story development, but the sequal of HxH (if we ever get one) might make up for it  read more 

1. Harem 2. Does "innapropiate stuff" to make the girls stronger 3. Both Heroines have uh.. big.. baseballs. 4. Girls fighting monsters from another world 

-Similar protagonists, who aren't perverted but are forced into it -Both perform lewd acts to increase the power of the female characters -Both are about some sort of war against a different race 

The male main character has to do indecent stuff with the other girls in order to increase their fighting capabilities, thus both are very ecchi anime. 

*Both are so over the top with the ecchi *Both have an mc who makes the girls stronger by doing sexual things with them *I started watching Masou and was immediately reminded of how over the top the ecchi in Testament is, so if thats your thing I know youll love both *the mc in Masou is weaker most of the time compared to Shinmai but I liked them both and they're far from the worst thing you sometimes encounter in harems *somewhat different settings one has mechs and the other is mainly heroes/demons *I enjoyed them both about the same and if you liked one, I'm sure you'll like the other. They just feel so similar for some reason. Just don't expect an amazing plot and story line but we all know why we're here  read more 

If you liked watched one, you will like watching the other for the exact same reason: both are super hardcore ecchi that borderline hentai. MC partakes in sexual acts to get stronger. In summary, chances are, you watched one of these shows for its hardcore ecchi content. You will probably like the other show for the same reason. 

Both have a harem. Both are borderline hentai  

MC is the lone male student at an all girls academy that trains mech pilots who wear revealing armor. 

Very much the same. Both main characters are the a new male transfer student in a all girl school. Both teachers are their sister. Both anime contain beautiful girls flying around with a high tech suit and all of the girls love the main character and wil fight for him. 

Both shows are Harem and Mecha. Both are situated at an all Girls School. MC has the power only the girls of that universe are to have. MC is seen as a pervert at first but all the girls warm up to him later. President of school is MC's sister. MC does lewd things unknowingly.  

Similarities: -Both anime is very alike with each other (characters and setting). -Both has harem and hot/cute girls. -Both anime has a weak yet developing MC. -Both anime involves mecha suits for fighting and battles. -Both anime's setting takes place on school and somewhat futuristic due to its technology. Differences: -Infinite Stratos minimizes the ecchi level throughout the series while in Masou Gakuen HxH, it shows BARE BREASTS and often in a point wherein they really wanted to have S-. -Masou Gakuen HxH in terms of the characters' energy on their suits, they need to be stimulated for them to be more powerful or regain energy to fight back and more while in Infinite Stratos, suits are just worn also does have energy but has no need for stimulation of the MC to the girls. -(Anger Alert) Infinite Stratos' MC is super dense, wherein he has 99.98% no clue of what the girls are really trying to do and trying to catch his heart. -Infinite Stratos is an 'all-girls' school where the MC is transferred or forced to study while Masou Gakuen HxH is combined men and women at the same academy. -Infinite Stratos' MC is the only man who can wield/pilot his suit because it is said that girls only are the ones who can pilot an IS. -  read more 

Both shows are harem, ecchi, and mecha anime. The male protagonist never is seen as the strongest character in either series, and the male protagonist's sister is the authority figure of the show. They both battle against robots or other mecha. These two shows are essentially identical, with Masou Gakuen HxH having more ecchi scenes and a more fleshed out plot.  

Events take place in the High School Female figures similar And it depends on the nature automatic weapons, uniforms 

Both have the harem and romance genre present, but Masou Gakuen has a lot more ecchi Both have mecha and both involve the characters fighting alien invaders in said mecha  

The story is kinda similar even the characters. It has mecha battles which is OK, I guess. Both shows have one male and many female harem type and ecchi is heavy. 

Both shows share similar ideas, with the main character being able to 'power-up' the girls through explicit means. They both also share similar characters (with the girls) such as the assertive one and the slight tsundere  

Both have that same romance, comedy and ecchi where it involves girls with super powers that needs some boosting up from a guy who has to play with them.  

You “Level Up” by doing certain things with girls. 

Both series have the central premise of super powered individuals fueling their abilities by erotic bonding with female partners. The main difference is that Masou Gakuen HxH is a harem series in which the protagonist is the one who powers up his Heart x Hybrid teammates, while in Seikon no Qwaser the qwasers draw their power -from- girls, and most qwasers are paired off in groups of two (there is a lot shuffling of partners between characters and the protagonist has multiple love interests, but in the strictest sense Seikon no Qwaser isn't a harem anime). They also differ in the respect that Masou Gakuen HxH is mainly a futuristic science fiction series and Seikon no Qwaser is an urban fantasy, but both works blend science fiction and fantasy tropes in their worldbuilding. Both series have a heavy focus on fanservice and ecchi content, while also being built around a relatively complex plot with a great deal of fighting and action. There is also substantial amount of character develop for the casts throughout both series, and feature similar themes of overcoming abandonment and mistrust. Both shows have a variety of attractive female characters playing central roles in the story, though Seikon no Qwaser has a greater balance of male and female characters. In terms of fanservice, both shows heavily feature large breasts, Gainaxing, clothing damage, and romantic intimacy between the main characters. Masou Gakuen HxH mainly sticks to sexual foreplay, while Seikon no Qwaser's major theme is erotic lactation, though there is also instances of other stuff such as BDSM in both shows. In terms of non-ecchi action, Masou Gakuen HxH has more fighting and better animated action sequences (and fairly impressive animation in general), while Seikon no Qwaser delivers a more layered and dramatic storyline (especially in the manga) and evokes a bit more emotional depth from its characters. Anyone who like one series is likely to enjoy the other. read more 

Both shows are incredibly ecchi shows which borderline on hentai at times. In both cases, powering up is gained through sexual interaction between the pairs (although it's only limited to mostly boob groping to keep it non-hentai). They both also tie in fantasy elements to a real world setting  

Same thing but with mechas (mecha suits) instead of magic 

in my opinion, both anime have a relaxed story, we are always treated to by many fan services, i mean alot of fan servis. especially if you love ecchi and harem you should definitely watch it.
