Mikan called Rito by his name because of her repressed attraction.Sometimes in their childhood Mikan confessed to Rito or telling other people about her crush and get a reply that she cannot marry her brother. Hence Mikan calling him in a First Name Basis to make some distance between them, this behavior continues to her puberty even though she know it's hopeless now (she think).
Golden Darkness is Eve from Black Cat.Not long after the events of Black Cat, the Deviluke Empire invades the Earth-like planet the series takes place on and takes over without much trouble. In the chaos of the invasion, Eve is separated from Train and Sven and somehow stricken with Laser-Guided Amnesia that erases all memory of the previous year or two of her life. With her only remaining memories being her time in service to Torneo, Eve begins making a living doing the only thing she knows how to do - hunting down and erasing targets for cash. Her extraterrestrial contacts take her off-world, where she becomes the infamous Human Alien assassin we all know and love.
Lala is literally sent from Hell to ruin Rito's life.
Rito is somehow related to Keitaro.How else do you explain the fact that he isn't dead yet? Not to mention all the Accidental Pervert moments and accidental groping.
Mikan's maturity will not survive early pubertyTheir father is 24/7 on his manga, and Mom is pretty much the same in the world of fashion. Not the worst anime parents by any standard (Paging Mr. and Mrs. Hayate, Beyblade's Judy Tate, Mayu's Mom from Elfen Lied among countless others) but still not the most engaged. Rito was once a together athlete whose only lack was not confessing to Haruna, and he seemed on the verge of that. Then, he gave soccer up to care for a sister who can plainly care for herself—or can she? See, Rito, even in his denseness, knows that the Yuuki clan loses its sense of responsibility and many social skills once adulthood begins to kick in, and he wanted to be there for her as she fell. Evidence : At story's start, while always caring for him, Mikan is head and shoulders above her brother in almost all things, even knowing how he should handle girls better than he, and snickering constantly at his expense. Now she is a raging pile of bro-plex, teased by her friends just as he was, and noting that he really does rather well versus the insanity of life with Lala. Soon, any traces of the uber-fiend Ruthie Camden will vanish from her, and Lala will have her porting starkers into the boys' changing area, with her hair and eyes exploding while she stutters.
Yami is a lesbian.She constantly attacks all the guys who do "ecchi" things, but when the girls start groping her, she just starts blushing. It's practically the only emotion she shows. Not to mention that she's constantly hanging around with Mikan, who, as we know, is incredibly sexed up for a girl of her age. Not the mention that the pairing would be incredibly cute.
It's not because of her brother that Mikan doesn't date.
If/when To Love-Ru somehow resumes...
The spinoff will feature Yami as a main character.Yabuki obviously has a fairly strong attachment to Yami/Eve's character, seeing how he's used her in two separate manga so far (three if you count her cameo appearance in Mayoi Neko Overrun) yet he didn't really do a whole lot with her in TLR. But notice how she's featured prominently on the promotional art for the new series, and it's apparently named "To Love Ru: Darkness". Assuming the source is correct, this would be a good way to alter the series' primary love triangle and get rid of Haruna by replacing her with Yami.
Rito and Mikan are Not Blood Siblings.Momo has no problem considering Mikan as a target of the "Harem Plan". Maybe she knows something the audience don't.
we will see some kind of MIB organizationA perfect Expy of Chronos and an interesting plot. Also, that can help to explain how the aliens do to integrate to society.
Momo and Nana are half-sisters of LalaIt was stated that polygamy is legal in deviluke. the king love women. It was never stated that they had the same mother. any question?
Momo will be Rito's first wife.Even though she is fine with any position, she is a bit greedy. Also, of all girls she is spending the most time with Rito, proving herself to be quite reliable.
Yami has the same drawback as YuriaThe first man she has intercourse with becomes her master, forever. That's why she is violently opposed to perceived male sexual advances, but only mildly protests much more deliberate harassment by women.
Lala didn't understand that Ren was a diffrent person from Run when she was a kid and she thought that Run had proposed to her.It would explain both why it took so long for her to remember Ren and why she kept treating him like a girl as a kid as well as her comment the she would wed him if he became a man. look at her. You'll probably want to hug her more than be scared of her, and besides, it seems to be the end goal of Momo to put any remotely attractive female who Rito interacts with into the harem. I wouldn't mind it actually.
Nemesis does not have an actual physical existence.She's some sort of computer virus or similar entity who is possessing Mea, employing her shapeshifting abilities in ways that Mea herself can't consciously use. Until the most recent manga chapter, the two of them hadn't yet appeared together without anyone else present; even that appearance, featuring bystanders watching the two of them with bewildered expressions, could simply have been people watching Mea have a conversation with someone they couldn't see or hear.
Rito is gayYou'd think that after having his face literally planted in more vaginas in a day than a porn star does in a week he would at least start showing showing some happiness about his "predicament", and yet his reaction is still consistently childsh terror at the age of 17.....
Rito is an unconscious practitioner of some kind of Confusion FuThere must be a reason why highly skilled assassins seem to be unable to dodge his accidents and one could be because they are used to predict their enemies' movements and Rito's don't have any recognizable pattern in them. That or Yami grown to like them after a while. One or the other.
Rito is (also) a master of Obfuscating StupidityHe does enjoy the ability to faceplant into female genitalia, but he realizes that if it gets out that he's doing it on purpose, it would be very very bad for him. Yui, Nana, Mikan, Yami, and Saki would all try to kill (or severely injure) him, and if Lala and Haruna found out, their opinions of him would drop considerably. Yeah, there are a couple of girls who wouldn't mind (Mea, Run, and Momo), but he certainly wouldn't trust any of them to keep the secret. So he keeps acting like he's doing it on accident, because he knows that as long as he does so, he'll keep getting his daily dose of boobage with minimal risk.
