Both manga feature a servant\familiar\item turning it's owner into it's own servant. One manga is very crude and the other is rather on the ecchi side. If you don't feel discouraged and you liked on of those two, then you might want to check the other one too.
P.S. Neither of those manga is really good...
All Shinta wants is to find a girlfriend, and constantly falls in 'love at first sight' with his classmates. Unfortunately for the boy, none seem to reciprocate his intense feelings, and thus, he does the only thing he can think of – he visits a local shrine to hopefully have his wish granted. Much to his surprise, Shinta encounters a god at the shrine who decides to grant his wish, and the next morning, Shinta wakes up next to the lovely goddess Isana. But all wishes come at a price – it's that time of year when gods throughout the world battle it out for territory, and each deity like Isana must use a human as their champion. Now, Shinta must fight countless enemies for his newfound girlfriend, even though she doesn't seem to want to give him the time of day!
I can't really point out the similarities between those two (other than the male lead fighting using a very unique weapon), but something reminded me of GAN☆KON when I was reading Tsugumomo. Anyway, it's just a hunch, but you might like one of those two if you liked the other one.
P.S. Tsugumomo can be very crude at times.
It's mostly a gut feel, but those two manga remind me of one another. I know that female leads in both series seem similar, though the one in Kami Sen. is nowhere near as extreme as the one in Tsugumomo in her actions. What else is there? That I'm not sure, but you can check it out yourself. Just keep in mind that the content of Tsugumomo is crossing a few lines (the further you get the more extreme it gets).
Yuuto Amakawa has had a tough life. Seven years ago, both of his parents were tragically killed in a car accident, leaving him without a single living relative. His friend Rinko Kuzaki has taken care of him every since. Yuuto's sixteenth birthday has arrived, but instead of a birthday gift of a normal life he meets Himari, a catgirl samurai who swears to protect him. Within weeks Yuuto's life is thrown into chaos as his family's dark past comes to light. With demons appearing around him, Rinko and Himari fighting for his attention and a sinister plot beginning to surface, can Yuuto live the normal, safe life he wants so badly?
In both Omamori Himari and Tsugumomo the male lead is approached by a female youkai on his 16 birthday and is made into an exorcist. In short the story is very similar. The characters in Tsugumomo are much better written than those in Omamori Himari and thus more likable, but the manga itself is extremely crude. On the other hand Omamori Himari has s******* of fanservice. Either way if you liked one of those two, it's possible that you could like the other one too.
