both are a bit crazy except namiuchigiwa no muromi-san is about mermaids and teekyuu goes at lightening speed 

Both have cute monster girls who look similar and have similar personalities. They also are both funny! 

Similar artstyle....too similar in my opinion...and characteristics of each girl, for example : HackaDoll No.1 = Muromi-san........... HackaDoll No.2 = Levia-san........HackaDoll No.3 = Yeti girl..... Both shows have awesome OP songs [ damn, I just love them... and you will also ] Both relies heavily on comedy genre.... fast paced action/gags...which leaves you a feeling that you want more and more.... pretty much there is no storyline, but there is one thing that HackaDoll anime doesn't have like Namiuchigawa no Muuromi-san.... that's male MC.... but I think that he is not needed in HackaDoll because it's enough already of these 3 HackaDoll's.... In shorter... it's basically the same show, so if you like'd one, you WILL like another by 100%.. read more

> SIMILARITIES: Everyday life comedies about "I got a new buddy who is not a human" - Both stories are about a human spending time and building a friendship with a creature from another area of his/her world (mythological creature or gods). - This creature have a half human, half animal body. - This creature is a weirdo among its fellows (the funny weirdo not the creepy one) because of a strong (but yet something annoying for the human which it so funny for us watcher) personality. - The stories take place in the human world but we get to discover the "other" world and the other weirdo friends of this endearing creature. We also discover that despite their origins, they have the same problem (annoying but great friends, perverts, heartbreak and parent issues, etc.) and even lifestyle (especially in Muromi-san for the latter) > DIFFERENCES - Muromi-san is only about trying to make you laugh like hell (you can guess it just from the opening) as in Nekogami sometime they try to make you cry (don't worry, only one or two drops no more) - Muromi-san's story is really focus on present and the creature: the story start when they met and we don't get to know the past or current life of the human so we only know him through Muromi, but we get to know some stuff about the past life of Muromi-san. - The humour is more composed in Negokami: no boobs bashing for example... (yes it's a must-seen scene in Muromi-san) read more
