If you liked the To Love-Ru anime, the Anime-Planet community thinks you'd like:
Ever since Tomoki was a boy, he’s dreamed that the girl he loves vanishes into the sky. However, while he’s convinced it’s just a dream, his classmate Sugata is convinced that it’s related to an alleged ‘new continent’ that’s floating around the planet. According to Sugata’s calculations it’s set to pass above their town at midnight, and sends Tomoki to check it out. Little did Tomoki know that at that moment, a scantily-clad angel would fall from the sky! Calling herself a pet-class Angeloid named Ikaros, she promises to fulfill Tomoki’s every wish. Now, Tomoki is able to manipulate panties and do equally as perverted things with ease; but what is Ikaros really here for, and are her motives as pure as they seem?
To Love Ru and Sora no Otoshimono are quite similar in that both stories revolve around an sexy and extraordinary girl that came from the heavens (outer space in the case of To Love Ru) becoming hopelessly devoted to a schoolboy on Earth. Both have wonderfully echi comedy revolving around this situation, and the various high tech devices created by the visitor.
Although Lala (to love ru) and Ikarus (sora) couldn't have more different personalities, if you enjoyed one series, you'll enjoy the other!
Big boobs, sudden girlfriends, perverted situations; both To Love-Ru and Sora no Otoshimono Forte have these properties in spades. These fine ecchi festivals, feature out of this world characters with superhuman abilities, impending threats and unknown dangers, as well as fist upon fist of yummy boobie groping. Who needs a coherent narrative when you have fishing for breasts or clothing that explodes? If you liked one of these you will probably want to check out the other.
While visiting the legendary Tattoon tribe, high school delinquent Hideo's mother traded her son's hand in marriage for the ability to continue her research -- unbenounced to Hideo, of course! To him, women are self centered, indulgent, and the source of all troubles, which makes meeting the eager to please Nima all the more unappealing. Now, with Nima and class president Fujimatsu both after his love, and new enemies arising from the woodwork, will Hideo live long enough to fight another day?
Tattoon Master is far older than To Love-Ru, but both have a similar premise: a girl is thrust into the life of an unsuspecting man who wants nothing more than to NOT be with her! Comedy and hijinks ensue. To Love-Ru is far more ecchi, but fans of one may enjoy the other.
Ren and Mihato Uesugi have moved to Chiharu in order to find work and a place to live, but it has proven difficult to find employment. Through a series of events the duo finds itself in the prestigious Kuonji house - and subsequently accepts live-in maid positions! Famous Shinra, inventive Miyu and youngest Yume are tough customers to wait on, but with the help of the ex-militant head-butler Colonel, head maid Benisu and other wait staff, Ren and Mihato might just learn what it takes to be the best maid or butler you can be. Their jobs are not easy, though, with everything from inappropriate sibling love to household games to handle!
I'm simply recommending these two because they are both light hearted animes with a story you can more or less care about. They are both harems with there typical anime gags and relatively similar humor. Note: They do have excessive amounts of deviant behavior. If you are into that and want some quick laughs either will do.
Kazuto Tokino lives his tranquil life attending high school by day and running the family bath house by night; but his peace is all set to change. One fateful day, the Beautiful Princess Valkyrie crashes her spaceship into Kazuto’s public bath, killing the high-schooler outright! In order to revive him, Valkyrie gives the teen half of her soul, with the unfortunate side-effect of reverting the princess back to a child in both body and mind. Now the young Valkyrie is moving in to the bathhouse and, with her brash sister Hydra and over-protective catgirl maid Sanada following close behind, it seems Kazuto’s peaceful life is long behind him…
Like ecchi? Like busty aliens? Well then both of these shows are for you! While Valkyrie in UFO Ultramaiden Valkyrie spends most of her time in child form, there are still plenty of other 'bouncy' aliens to satiate any ecchi pallette. Both series also share a similar style of comedy, so if you liked one then you may enjoy the other.
