If you liked the Rizelmine anime, the Anime-Planet community thinks you'd like:
After his apartment burning to the ground and almost being killed by a falling metal object, Ohmura Takeshi is ready for the afterlife. Luckily, a beautiful angel appears to heal his wounds and inform him that if he stays with her, no harm will come to him. The catch? His long-lost deadbeat dad has passed along a curse: he will experience nothing but sadness in his life. Now, after changing to a human to maintain close contact, Elle will stop at nothing to make sure that a bit of happiness comes into Takeshi's life, but not before first learning how to be a human!
The main protagonist for Rizelmine is very similar to Happy World!, especially on their reaction + behaviour towards their new clingy companion. The plots are similar, and they even have similar elements (such as the slight fanservice). Happy World had great character design and lots of use of colour. Rizelmine was much more fulfilling to watch.
Sawamura Seiji is the most notorious delinquent at his high school -- always getting into fights and causing problems, leaving him single and unlucky with the ladies. After another long day of rejection, Seiji discovers that the love of his life might have finally appeared, but in the unlikeliest of places... his right hand?! Now, in addition to dealing with daily fights and the gossip of his classmates, Seiji must handle a new problem of embarassing proportions: Kasugano Midori, a pretty young girl in place of his hand, who happens to have fallen in love with him!
Both Rizelmine and Midori Days are about boys who are unlucky in love, but then suddenly a girl appears who is absolutely in love with him (and he wants nothing to do with her but he can't get rid of her).
i both animes the male lead at first hates the female lead but later on his attitude changes and at the end he breaks into tears.....
Rito Yuki is a bumbling boy who wants nothing more than to confess his love to the lovely Haruna, but a variety of obstacles always seems to stand in his way. One day, while relaxing in his bathtub Rito found his hands full - literally - with the breasts of a strange alien girl named Lala who suddenly appeared in his lap! She is the princess of Planet Deviluke, and she has run away from home to escape the prospect of an arranged marriage; and unfortunately for Rito, his accidental groping is the traditional engagement ritual of his otherworldly guest! Deviluke's emperor will destroy Earth if Rito backs down from his "proposal," but all he really wants to do is be with Saruyama! Naked antics, magical powers, misunderstandings, Lala's marriage-happy family and Rito's own shyness are many of the barriers he must face in his attempt to win the real love of his life – that is, if Lala doesn't win him over first!
Both main characters are forced to marry a girl that they don't even know and this causes troubles with the boys love and normal life, the funny and heart warming mood is present in both animes, you'll probably like one if you liked one,
Both anime are about a bubbly girl who forcibly declares herself to be the protagonist’s endearing wife. Unfortunately for this so-called “wife,” her “husband” already has eyes for someone else (too bad =/). Because of the latter, lots of comedic conflicts arise to annoy the male lead without rest. I assume you liked Rizelmine/To Love-Ru, and I will assume that you will like the other.
Shirase Akira is a genius hacker who has earned the nickname "Battle Programmer Shirase" (or BPS for short) for his incredible talent. From saving corporations to global security, BPS is always willing to help a hand -- for the right price. But for skills like his, money is not an option, so be sure to have specialized computer parts, sold-out tickets, or huggable life-sized cat girl posters to spare! With BPS in charge, no computer is safe! That is, if he can manage to stop being a complete slacker...
Both BPS and Rizelmine are absurd comedies that present themselves with a straight face and contain plenty of ecchi, for the more perverted audience members out there. Both series are shorter in length then your average TV anime, and both series rely on telling the same joke over and over to a hilarious effect. For example, in BPS there is a certain situation that happens almost exactly the same way every other episode driving the "plot" forward. In Rizelmine, there are situations and reoccurring jokes that get reused over and over and over until you lose count. While the plots and settings of each anime are different, the type of humor used in both is very similar. Therefore, if you enjoyed one of these shows you will definitely like the other.
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?
