One should always understand other people’s customs before making commitments. Unfortunately, Rito had no idea the planet Develuke even existed when their Princess Lala teleported naked into his bathtub, let alone that touching a girl’s breasts is how they propose marriage! Given that he was in the tub when she appeared, Rito’s now engaged to a beautiful girl with a pointed tail. What's worse: the girl that Rito really loves is still completely unaware of his feelings.
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.
Sadness be gone! Though depressed people are scattered across the world, there are those from a parallel world that are here to help. Known as Juuden-chan, these busty ladies use their special powers to charge up the mentally dejected and earn a living in the process. Aresta and Plug are two Juuden-chan who, while performing their duties, discover a boy named Sento. However, he’s different than most humans: unlike the rest of mankind, Sento can actually see them. Now, in addition to their duties helping the depressed, Plug and Aresta must juggle watching their favorite hentai, getting into trouble, and being hit by Sento’s bat which causes them to urinate and become aroused. Perversions abound for these two rubber suit-wearing, otherworldly beauties!
Asobi ni Iku Yo! and Fight Ippatsu! Juuden-chan!! are two very fanservice-y series that involve extra terrestrial beings. Or at least life forms that do not originate from Earth. I do think you'll like one anime if you enjoyed the other because there are some similar issues that arise in both anime. Both series touch upon science fiction elements whereas Asobi ni Iku Yo! features some cool gun-action and Juuden-chan is a lot more silly. You also have these girls in skin-tight "space" suits while at work. The main guy somehow gets involved in outer-Earth missions and that's when more powerful forces take interest in him. I think Juuden-chan takes a more "ecchi" role with its urophilia while Asobi ni Iku Yo! takes almost every opportunity for nude shots. Take your pick.
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.
One day, while testing out his new video camera on a bridge in town, Kaito Kirishima sees a bright blue light in the sky and is inexplicably knocked over the side, awakening the next morning in bed with no memory of the event. But upon heading to school, the boy notices a new face that’s familiar to him somehow - her name is Ichika Takatsuki, and she’s new in town. Kaito’s friends, noticing his interest in the girl, all resolve to make a movie this summer and cast her as the lead, to which she immediately approves. Now, the group embarks on what will be a truly memorable summer that no one will forget, as Kaito and Ichika slowly, and clumsily, begin to fall in love.
Both series have an alien that came to Earth from another planet. They both fall in love with the main character, and both have difficulties along the way. Both these series have love, drama, and a series of problems the characters must overcome, and both are very enjoyable to watch. Ano Natsu de Matteru has more of a romantic feel to it, while Asobini Iku yo! has more of an ecchi feel to it. Both however have a similar feel and if you liked one, you would most likely like the other.
On a day that seemed ordinary, a spaceship crash landed in Tokyo bay, filled to the brim with beautiful aliens that would come to be known as DearS. Since that day, though all of Japan seems to have gone DearS-crazy, one high school boy named Takeya it still not impressed by the phenomenon. But things change for Takeya when he finds a lone DearS girl on the side of the road, who forces herself into his apartment, and his life! Now, he must brave a plethora of complications, misunderstandings, and embarassments, when all he wants to do is be left alone!
Cat Planet Cuties and DearS are basically the same anime. Wether we're taking about their abilities, romantic advances, realistic-esque view, or even the basic setup of characters, it's all ridiculously similar. If you liked one I'm sure you'll like the other.
