If you liked the Asobi ni Iku yo! anime, the Anime-Planet community thinks you'd like:
Yukinari is blessed with an clinical fear of women, commonly known as gynophobia. In addition to his mental ailment, he has the misfortune of being short and weak, making it easy for women to overwhelm him further. Even when his childhood friend, Kirie, approaches him, he immediately breaks out in hives. Thus, life is very lonely for Yukinari, until suddenly in the strangest way possible, he is transported into another world, and into the arms of the beautiful shoujo, Miharu! This time, for the first time ever, he doesn't react. Could this be the start of something special?
These two anime are very similar. Both have a female character some to earth from another planet and live in a boy's home. Both try not to really focus on too much plot and try to have a good time. While plot does exist, a lot of it is just silliness and fun.If you liked one, you should like the other.
When the infected approached Rei and Takashi's school, it led to a gruesome blood bath that left the majority of students and staff dead or turned into the zombie-like monsters that have spread throughout the world. Together with a handful of other survivors, Rei and Takashi set forth to find their families in a world that is rapidly detoriating. Governments have collapsed, the killer disease is out of control, and people everywhere are trying their best to simply live through each day...
Action, ecchi and the harem elements are similar. Despite the difference in the base genre(scifi vs horror), the plot and characters have more in common than the typicall highschool ecchi show in that school life actually plays a minimal role.
Overally HSOTD is better, mainly because the cookie cutter love polygon plot is in the background wehreas it takes center stage in Asobi ni Iku yo just as it does in most ecchi shows.
Both have similar stories beginning when an alien girl suddenly drops in on a normal High School boy. In To Love-Ru it was the alien princess Lala and in Asobi ni Iku yo! it ended up being the cat girl Elis. Both shows feature an eclectic cast of females all trying to make the lovable loser their own. Same ecchi comedy and both are easy watches since neither of them build up a complex plot of any kind.
Ataru is one of the most desperate womanizers alive, and a man whose life is about to become complicated. When aliens invade, he discovers he has been chosen at random to be mankind’s defender, and must play a game of tag with the beautiful alien princess Lum to decide the fate of the planet! After chasing her with all of his crafty techniques, Ataru finally wins, but his victory also means he must marry the princess herself! Now, with strange alien visitors and a jealous wife to handle, Ataru still manages to keep an eye on his ultimate goal: having his own harem!
If you like Asobi ni Iku yo! you'll like Urusei Yatsura because they're both about a space alien girl who is in love with an ordinary human. And the male leads of both of these shows have a female childhood friend who is in love with him.
