Jitsu wa Watashi wa

Rosario to Vampire and Jitsu wa Watashi wa are series of romantic comedy where the protagonist discovers a vampire girl, becoming its first friend. Where in addition he is attracted to her despite her appearance and accept it, watch over her so that his friendship does not die, also discovering more people with different particularities in his own school. Different comic occurrences will pass through the space, where the friendship will be tested and filled with joy to that girl of whom she had never felt. 

Both male MC are attending the schools where there are monster appearing like humans. Both have female MC who are vampires. Both are harems. As I watched "Jitsu wa Watashi wa" I immediately thought of "Rosario + Vampires". So I felt that there was a strong similarity between the two.  

Supernatural harem surrounded by monster girls. Although the main character only pursues one girl, he is still chased by others. Like Rosario + Vampire, Jitsu wa Watashi wa both have a vampire girl as the main female lead that is the pursued by the normal and useless yet "charming" main character. 

Both SoL harem shows deal with an ordinary human dealing with monsters (vampires, aliens etc.). In both cases, the MC carries a secret that must not be revealed to the public  

male protagonist who is human but is getting to know several girls who are not human but it is the vampire girl who is the main one besides being the love interest on the part of the protagonist. 

anime with same themes: school, demons, secret identity - Iruma, human who is in school full of demons/devils and tries to graduate - Yukou, a vampire who is in school full of humans and tries to graduate  

Similar art and colour palette. Both stories are somewhat similar while in JitsuWa the MC has to protect the identities of others in IrumaKun he is the one that has to protect himself. Both supernatural school settings. Both lightheart comedies. The biggest difference amongs them is that Iruma matures as a person but as a warrior too since Iruma-Kun is even more shounenish than JitsuWa. Iruma-Kun is the closest thing we'll ever get to a decent adaptation of JitsuWa. 

Both have the same plot were it involves boy who is in the company of freaks, but JwWw has more subtle freakish characters are disguise as normal people while in MMnIN the freakish characters are profound. Also, the guy in one anime is very much a wimp compared to the guy in the other anime. On a harem level one is a true harem, while the other is a false harem.  

Similarities: -Both have monster girls -Both are a harem series to an extent -Both have an average main male character -Both main male characters have to choose one girl -Both start out with one love interest but eventually more girls show up -Both have fanservice -Both have an array of interesting characters -Both aired in the summer of 2015 -Both have catchy theme songs Differences: -In Monster Musume the setting mainly the main protagonist's house and in Jitsu wa Watashi wa the main setting is the highschool -Monster Musume has adult characters while in Jitsu wa Watashi wa the characters are mainly teens. -Monster Musume is more fanservice based -Monster Musume has more love intrests -In Jistu wa Watashi wa the characters are more shy/blushy -Monster Musume is a more sexy series while Jitsu wa Watashi wa is more cute -In Monster Musume everyone knows monster girls exist but in Jitsu wa Watashi wa is has to be kept secret -Monster Musume's girls are a lot more monster-esk  read more 

Jitsu wa Watashi wa and To LOVE-Ru both series: - They have a protagonist who wants to confess to the girl he likes, but certain facts prevent him from doing so. - The protagonist meets a girl who is really (in Jitsu wa Watashi wa is vampire and in To LOVE-Ru a alien), where he must hide that truth before the others, so that he does not return to the place where he belongs. He also discovers that there are more people like them, who hide their true nature. - We have the class president who hides her feelings until she says enough is enough. - We have the character who changes sex, who is a friend of the girl's childhood. Two series of romantic comedy, with touches of harem, where any madness can happen (constantly). read more 

airheaded main female MC's, but super kawaii and lovely? :D turn on your airconditioner at full power, cuz you will be melt by the cuteness of these 2 female MC's. if you have watched "To Love Ru", try "Jitsu wa watashi wa". and enjoy the fun :D 

Nogizaka Haruka no Himitsu and Jitsu wa Watashi wa begin demonstrating the undesirable traits of the male mc juxtaposing to the elegant, perfectionist traits of the female mc. The Male mcs of each respective series were both considered to be losers, but that all changed the day they discovered the female mcs darkest secret, Noziaka being an otaku and Shiragami being a vampire respectively. This tragic situation caused the Male and female mcs to befriend each other and eventually become a couple within both series. 

Both are pretty funny Rom-Coms with a similar style of comedy and cute girls in a high school setting, also in voth animes they have to keep a secret that is very importan for the plot. Both have really good OP songs and soundtrack. The main difference are that the girls in Jitsu wa Watashi wa are monster. 

Conflict of the show involves keeping the secret the females have. Similar cookie cutter characters, will they/will they not type of show. both shows are comedic heavy, similar tropes; makes for decent popcorn flick on a hard day of work 

I liked them for basically the same reason. They both like to poke fun at other more-average romcoms. I fell in love with the heroines, and the main characters are lovable all the same. I can REALLY get behind the romance in these shows, too. SnH and JwWw seem more alike the more I think about it * similar heroines, including the supernatural elements (all played for laughs) * the humor is also very similar, though Jitsuwa has less comical violence * they have shared plot points * meta-humor is very much present in both (though SetoHana is more of a full-blown parody, and Jitsuwa more-or-less rides the same fine line as shows like JoJo) NOTE: the ecchi levels in both series are about the same, in case you're wondering read more 

D-Frag has similar goofy and funny comedy. Both shows have very likable characters. Both shows have you rooting for one girl in particular. Both male characters aren't typical cookie cutter designs. Both animes have a cute, funny, and unique harems. 

Rom-com anime with vampiric main heroines trying to live a normal high school life but the MC accidentally found out about their secret. Hilarity ensues. 

Bizarre creatures and demi humans were gather into one.. as they collide The amount of refreshing a slice of life theme between each other is truly remarkable.. idea... In order to live one must hide their secrets unlike in this one... People mostly having a normal living..  

When you encountered unnatural events but ended up in other way. Anyway, they're both good.
