UFO Princess Valkyrie

Kaishaku created anime; displays cameos of their animes: Kannazuki no Miko, UFO Princess Valkyrie, Magical Nyan Nyan Taruto, Steel Angel Kurumi. In the UFO Princess Valkyrie prospect, it displays a character who resembles Valkyrie. 

In both anime the badass female leads are transformed into cute lolis. In UFO Princess the female is an alien while in Tsugumomo a youkai. Both have loli ecchi (and sometimes also larger women) to enjoy and have some comedy. 

Angelic females taking interest in a very plane and boring character. The main difference of the two is that one is more childish while the other holds a mature tone. There is obvious plot differences but for the most part the concepts the same. A Man falls in love with a angel. 

I find these two very similar because they are both about cute girls from superior races who fall in love with earthlings and get through a lot of difficulties to be with them 

Silly fan-service anime about aliens coming to earth and falling in love with random humans. Valkyrie is a little more on the humor side like DearS is a little on the uh, ecci side.  

Both are very similar in many ways. The obvious being that the main girl who is an alien princess ends up coming from space and living with the main character. The only notable differences is that UFO is far less ecchi. Aside from that they are more or less the same with a similar harem feel to it, however on my opinion UFO is done better. 

Same story; difference is that one is serious is and the other is less serious. In both anime an alien princess comes to Earth and interacts with a male MC (and of couse fall in love) and several females around him (an imouto and osananajimi in both anime). Yoake Mae Yori is the serious one, UFO Princess is less serious (though it gets serious at the end). 

Little spoiled blond-haired girl, maid and young boy as main characters + unreqiued love. 

Both stories are about an alien girl come to earth and accidentally killed the Hero. Both Heroine are taller and older than the Hero. 

both the main characters are simiple guys surounded by hot alien chicks, one more so than the other. they both have alien royal families the pressuring the guys to get married. they are similar in other aspects other than the plot; they are both funny, ecchi, and also have some action seens - tenchi more so than valkyrie. 

A chibi/younger version of the female protagonist is bonded to the male lead and only in special circumstances changes back to their original forms. 

Both titles contain over the top comedy with ecchi-ness thrown into the mix. Neither are that well known, but should be checked out by those who love this style of genera.  

they are very similair sci-fi setting, catgirls, random humor, if you liked either of these, you should try this one.
