Seikoku no Dragonar

Pretty much the same except a role reversal. A problem student with no talent ends up summoning a human familiar, known in Seikoku no Dragonar as a "Parr" which is unique to everyone else. The boy character in both shows is named "dog" by their master/parr.  

-Both main protagonist are problem child -Both story start with no parr or familiar with and ends up summoning their partner to be in a human form -Both have a master-slave relationship Note: Except for the role of the main characters are interchange. 

These shows are exactly the same. If you loved one, you will probably love the other. Technically there is a bit of a role reversal, but as far as how the characters interact, the roles are the same. The female lead if fundamentally weak with tremendous latent power, the male lead is her "sword", or in her words, her "dog". I am almost convinced that at some instances they handed the voice actors the script from Zero no Tsukaima, something I didn't mind because I am a huge fan. It is classic action, fantasy, harem, with a tsundere female lead. 

Same type of main character, same type of main female character. They both have the master-servant relation. And in both animes there are crepes..  

Both of them involve a very strong Main Male Lead, Everyone wants the D, and both involve a "master and summon" type relationship that gets built to be something more. Very Good show in my opinion 

Each main character has problems in school and also have problems summoning their familiar/parr. But when they finally do they turn out to be human and Each character has problems with their parr/familiar 

Both Zero no Tsukaima and Seikoku no Dragonar have a little to do with social structure and were you belong in a socitey. They also have malfunctioning relationships with there summoned one and explore different personalities of Charters and how to deal with them. Zero no Tskaima and Seikoku no Dragonar are also similar to allow us to escape from the laws behind our own world and explore a new world that wouldn't make sense to our world 

Pretty much the same sort of magical setting, with the master and slave elements.  

Both are action ecchi comedies involving magic. Both characters meets violent tsundere pettanko girl as well as other girls. Sikoku no Dragonar is about dragons, Seirei Tsukai no Blade Dance is about spirits. Both take place at school. 

a boy forms a contract with a naked loli girl that is actually a very special dragon(seikoku no dragonar)/spirit(Seirei Tsukai no Blade Dance) while going to a high school for people like him (but then less over powered because protagonist and all). both animes are filled with the needed fanservice to give it the ecchi tag and the art is very similiar and so is the feeling you get while watching it. 

Both shows share similarities with the cast's personalities, as well as feature a supernatural girl who serves as the MC's aide (and who has an obvious crush on him) 

Similarities: -Both anime are really alike in terms of the "Reverse Master Pact". -Both MCs are overpowered. -Both anime resembles each characters in both stories. -Both anime settings takes place on a Medieval Times. -Both anime have the same figure of a pink-haired girls as their "Master". -Both anime is in the genre of School. -Both anime have the MC's master as a Tsundere type. Differences: -Sereitsukai no Blade Dance features sword fighting as the point of their climax while on the other hand, Seikoku no Dragonar features dragons. At the same time, Blade Dance do not have dragons. -Blade Dance features an "all-girls" school wherein the Main Character enters it as being the only boy in that school while in Seikoku no Dragonar, it is free to all genders. -Blade Dance''s MC is overpowered ever since he was a child while in Seikoku no Dragonar, the MC becomes very strong after meeting his "Pal". -Blade Dance's nudity level contains no bare breasts, only jiggling and bouncing melons while in Seikoku no Dragonar: Bouncing Melons + Bare Breasts.  read more 

These 2 series are really similar and the only difference is that Machine-Doll is more darker and the their world's are different in my opinion 

Seikoku no Dragonar and Machine-Doll wa Kizutsukanai have many similar tropes and they deal with controlling the dragons and puppet dolls respectively. Both of these series have similar settings with Ecchi, Harem, School Life, Fantasy elements. The school where the MCs in these shows attend have battles and competition to take part in and show off their skills. The characters are similar too in the sense that how they react towards the main male character. Eco is exactly like Yaya and Silvia looks and acts similar to Charlotte. The male MCs in both of these shows have some sort of past shrouded in mystery. 

Dragonar Academy is almost identical to The Familiar of Zero but it shares many similarities with Unbreakable Machine-Doll as well, like the European setting, the protagonist's "challenge-everyone" attitude, and the presence of similar supporting characters. So far in the first episode of Dragonar Academy there has been a mysterious lady who in the past has had something to do with his partner, and a stuck-up, tsundere noble character who's taken an immediate rivalry with the protagonist.  

Both are about a boy who is infamous at his academy. Both partners are girls compared to dragons or other monsters. Both have a blonde girl that acts bitchy at first but later acts all nice. 

Tiny, tsundere, dragon girl anyone? 

Both anime based on dragons. Both protagonist have humanformdragon. In time their relationsships develop as a lover. Both of them funny to watch. At first look maybe you can say that it will become a ecchi anime but you never find any. So generally its worth a try.  

Both shows feature the standard male MC getting involved with a dragon female MC, who has a very eccentric personality and is very in love with the protagonist  

Both involve Battle Harems battling sinister demonic plots and conspiracies. Both series use comedy and slice of life effectively to tell their story.
