They revolve and male protagonist thrown into weird situations because of a female character (alien and human). Both invovle the marriage ofe this character to the princess of an alien planet with a scary father figure. Once I started these their hard to put down.
They have the same overall theme to an extent. Both revolve around a romance, action, comedy between a princess of a galactic conquerer and an average ordinary guy.
A year after their spaceship crash-landed on Earth, the alien species known as 'DearS' have been accepted into the Japanese citizenry. They are adored by many fan groups and trusted by most humans - with the exception of Takeya Ikuhara. Kind-hearted but resistant to change and skeptical of the DearS' seemingly-friendly behavior, Takeya tries to have as little to do with them as possible. But after he saves a girl from an incoming truck, and she turns out to be a DearS, Takeya ends up being far more involved with them than he could have ever imagined.
These two series are so similar its eerie. Alien becomes bonded to boy, boy is annoyed by it and begins to fall in love. They also both have cut-off anime made from them, and a similar art style. If you finished one and want more of the same, read the other.

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?
Two very good ecchi manga, with two very similar plots. Supernatural girl falls in guy's lap, bringing unwanted responsibilities and powers. Harem follows. While Omamori Himari has a deeper plot and ToLoveRu is more ecchi, both are great series that are worth a look.
Fifteen-year-old Tsukune Aono is average in every way; he has no hobbies, less-than-stellar grades and he's even flunked his high school entrance exam. His parents have managed to enroll him in a school, but it's no ordinary school! Tsukune will be attending the Youkai Academy, a place where monsters learn how to co-exist with humans! As the werewolves, vampires, witches and other monsters are required to retain their human forms, Tsukune - the lone human - is able to avoid their bloodthirsty gazes. However, he quickly attracts the attention of a number of devilish beauties including the vampire Moka, a busty succubus and even a young witch! It seems Tsukune's average life isn't so average anymore!
1001 Nights is also an anime which explores the aesthetic possibilities of animation making it almost central to the work. 1001 Nights contrasts with Angel's Egg as being more a free flight of whimsy and fantasy. It is sensual and expressive inhabiting an entirely different emotional realm to Angel's Egg, and testament to Amano's versatility. That said it is animation for animation's sake a rich and vivid exploration of movement and colour with very little in the way of a message or plot - and in that sense is very markedly different to Angel's Egg. It is however an exuberant work, and I highly reccomend it.
To Love-Ru and Rosario to Vampire are about weird relationships one revolving around an alien and the other a vampire. The human male characters fnd themselves attracted to this out-of-this-world character.
